Overprescription of narcotic pain medication is a major culprit in the present opioid epidemic plaguing the United States. The current literature on lower extremity opioid usage has limitations and would benefit from additional study. The purpose of our study was to prospectively assess opioid consumption patterns following outpatient orthopedic foot and ankle procedures.

Our study found that patients who underwent orthopedic foot and ankle procedures were overprescribed narcotic medication by nearly twice the amount that was actually consumed. Although we identified 4 independent factors associated with opioid consumption, the large residual standard error suggests that there remains a substantial degree of unexplained variance of opioid consumption observed in the patient population. Physicians face a challenging task of setting appropriate protocols when balancing pain relief and generalizable guidelines.

In an effort to minimize narcotic analgesia and its potential side effects, anti-inflammatory agents offer great potential provided they do not interfere with bone healing. The safety of ketorolac administration after foot and ankle surgery has not been well defined in the current literature. The purpose of this study was to report clinical healing and radiographic outcomes for patients treated with a perioperative ketorolac regimen after open reduction and internal fixation (ORIF) of ankle fractures.

Our study found perioperative ketorolac use was associated with a high rate of fracture union by 12 weeks. This is the first study to examine the effect of ketorolac on radiographic time to union of ankle fractures. Additional studies are necessary to determine whether ketorolac helps reduce opioid consumption and improve pain following ORIF of ankle fractures.

Reconstruction of the stage II adult-acquired flatfoot deformity (AAFD) often requires the use of multiple osteotomies and soft tissue procedures that may not heal well in older patients. The purpose of our study was to determine whether patients older than 65 years with stage II AAFD had inferior clinical outcomes or an increased number of subsequent surgical procedures after flatfoot reconstruction when compared with younger patients.

Our study found that patients older than 65 years with stage II AAFD have improvements in patient-reported outcomes and rates of revision surgery after surgical reconstruction that were not significantly different than those of younger patients.

Residual forefoot supination after correcting the hindfoot in stage IIb adult-acquired flatfoot deformity can be addressed with a dorsal opening wedge medial cuneiform (Cotton) osteotomy. The amount of correction is generally judged clinically, and there currently are no preoperative guides that can predict the size of graft needed. The aim of this study was to evaluate the correlation between patient and operative factors and the correction achieved with the Cotton osteotomy.

Correction of longitudinal arch collapse, as measured by the CAA, was primarily influenced by the size of the graft used for the Cotton osteotomy in a linear fashion. The preoperative CAA may help surgeons titrate the proper amount of graft placed intraoperatively.

A recent publication reported preoperative Patient-Reported Outcomes Measurement Instrumentation System (PROMIS) scores to be highly predictive in identifying patients who would and would not benefit from foot and ankle surgery. Their applicability to other patient populations is unknown. The aim of this study was to assess the validation and generalizability of previously published preoperative PROMIS physical function (PF) and pain interference (PI) threshold t scores as predictors of postoperative clinically meaningful improvement in foot and ankle patients from a geographically unique patient population.
  
PROMIS PF threshold scores from published data were successful in classifying patients from a different patient and geographic population who would improve with surgery. If functional improvement is the goal, these thresholds could be used to help identify patients who will benefit from surgery and, most important, those who will not, adding value to foot and ankle health care.

Many patient factors have been associated with higher or lower expectations of orthopaedic surgery. In foot and ankle surgery, the diverse diagnoses seen may also influence expectations. The aim of this study was to investigate the relationship between diagnosis and patients’ preoperative expectations of elective foot and ankle surgery.
 
Diagnosis of ankle instability or osteochondral lesion, female sex, non-Caucasian race, and lower Foot & Ankle Outcome Score daily activities subscale score were all associated with higher expectations. These findings may help inform and guide surgeons as they counsel patients preoperatively.

The historic treatment of Charcot foot arthropathy has been immobilization during the active phase of the disease process, followed by accommodative bracing of the acquired deformity. Evidence derived from modern patient-reported outcomes investigations has convinced many surgeons to attempt operative correction of the acquired deformity with a goal of improving quality of life.

Over the past decade, total ankle arthroplasty (TAA) has become a mainstay in the treatment of end-stage ankle arthritis. Currently in its fourth generation, the Scandinavian Total Ankle Replacement (STAR) is the only 3-piece mobile bearing ankle prosthesis available in the United States. Our current study reports implant survivorship at 15 years and patient outcomes for a subset of these survivors available for study.

We present our results with an INBONE I (Wright Medical, Memphis, TN) prosthesis that have a minimum of 4 to 10 years of follow-up and include a preoperative deformity analysis on outcomes.

Patients who underwent INBONE I fixed-bearing total ankle arthroplasty demonstrated significant improvement in outcomes at a mean of 5.9 years. Catastrophic talar component collapse did occur (2.7% of cases), but relatively rarely. The patients with preoperative coronal plane tibiotalar deformity had similar pain relief, function, and need for revision of implant components. Despite the presumed shortcomings of the INBONE I’s design, this implant showed promising results, with or without deformity, at midterm follow-up with survivorship of 90.6%.

Grading systems are used to assess severity of any condition and as an aid in guiding treatment. This study examined the relationship of baseline motion, pain, and observed intraoperative cartilage loss with hallux rigidus grade.

Irrespective of the grade, positive outcomes were demonstrated for both fusion and synthetic cartilage implant. Clinical symptoms and signs should be used to guide treatment, rather than a grade consisting of radiographic, symptoms, and range of motion factors.

Foot and ankle surgeons are increasingly relying on patient-reported outcome measures (PROMs) such as the Ankle Osteoarthritis Scale (AOS) to evaluate treatment options. The objectives of this retrospective cohort study were 2-fold: (1) to examine the AOS instrument using psychometric analysis and (2) to revise the questions on the AOS to improve the effect of questions on the score and remove redundancies.

The AAS is shorter and has improved psychometric properties as compared to the AOS. Further investigation is required to better characterize the clinical utility of this proposed new patient-reported outcome score.

The Ankle Arthritis Score (AAS) is a new patient-reported outcome derived from the Ankle Osteoarthritis Scale (AOS). This study analyzed longitudinally collected data from a cohort of patients in the Canadian Orthopaedic Foot and Ankle Society (COFAS) Ankle Arthritis Study in order to evaluate whether the postoperative AAS is associated with need for revision surgery.

TAR patients who reported higher levels of postoperative functional impairment, as indicated by a higher AAS, were more likely to require metal-component revision surgery. After adjustment for other patient factors, the risk of revision surgery increased with length of follow-up after TAR. This study provides further evidence for the utility of the AAS in the clinical setting.

Total joint surgeons have successfully performed hip, knee, and shoulder arthroplasty procedures in the outpatient setting without compromising safety, satisfaction, or results. The purpose of this study was to evaluate outpatient total ankle arthroplasty (TAA) as compared with overnight or extended inpatient stay, with regard to 90-day medical and operative complications, reoperations, readmissions or emergency room visits, and pain control.

Eighty-one patients underwent TAA who met inclusion criteria, and 8 had a complication (10%). A significant difference in complication rate was seen among groups (P = .01) but not rate of readmission or reoperation. Of 16 patients, 5 (31%) who were admitted for 2 or more nights following surgery had a complication, as opposed to 3 of 65 (5%) who were outpatient or admitted overnight (P = .01). There were no differences in frequency of postoperative phone calls, narcotic refills, or visual analog scale pain scores at the first postoperative visit. There were no adverse medical events.

Investigations using the Medical Outcomes Study Short Form 36 Healthy Survey (SF-36) and the American Orthopaedic Foot & Ankle Society Diabetic Foot Questionnaire (AOFAS-DFQ) have demonstrated a poor quality of life in patients with Charcot foot arthropathy. The Short Musculoskeletal Function Assessment (SMFA) questionnaire has been widely used in patients with a broad range of musculoskeletal disorders.

Charcot foot severely impaired the quality of life in patients beyond the impact of morbid obesity. This impairment equally impacted all of the functional and emotional domains measured with the SMFA as compared with population norms. This investigation provides a benchmark for measuring the impact of operative correction of the deformity. In addition, the SMFA appears to be a valid tool for measuring impairment in this complex patient population.

Traumatic hallux valgus is an increasingly common injury in the athletic population and represents a unique variant of turf toe. Failure to appropriately recognize and treat these injuries can lead to continued pain, decreased performance, progressive deformities, and ultimately degeneration of the hallux metatarsophalangeal joint. Limited literature currently exists to assist in the diagnosis, management, and operative treatment.

Overall, good operative results were obtained, with 74% of patients returning to their preinjury level of play at an average recovery time of 3.4 months. The impact of this injury cannot be overstated, as one-quarter of players were unable to return to play.

Few authors have investigated patients’ expectations from foot and ankle surgery. In this study, we aimed to examine relationships between patients’ preoperative expectations and their demographic and clinical characteristics. We hypothesized that patients with more disability and those with anxiety or depressive symptoms would have greater expectations.

The results of this study may help inform surgeons’ preoperative discussions with their patients regarding realistic expectations from surgery. Generally, patients with worse function and more disability had higher expectations from surgery. Addressing these patients’ expectations preoperatively may help improve their ultimate satisfaction with surgery.

The purpose of this study was to perform a histological comparative analysis of tibiotalar joint samples taken from areas of osteolysis adjacent to total ankle arthroplasties vs control synovial specimens to determine the reaction to and presence of polyethylene (PE) particles.

This study is the largest ankle arthroplasty histological analysis to show that areas of osteolysis consist of abundant polyethylene wear particles, present both intracellularly and extracellularly. Furthermore, these areas were associated with a CD163⁺ macrophage infiltrate and frequently a foreign body reaction with giant cells engulfing PE particles. It is likely that implant wear particles play a significant role in osteolysis based on the histopathology.

Lesser metatarsophalangeal (MTP) joint instability is a common cause of forefoot pain. Advances in operative technique and instrumentation have made it possible to anatomically treat plantar plate tears through a dorsal approach. Our goal was to evaluate the subjective, functional, and radiographic outcomes of plantar plate repair (PPR) from a dorsal approach.

We found that the plantar plate could be repaired through a dorsal approach with reliable outcomes. PPR was a viable option to anatomically restore the ligamentous support in the unstable lesser MTP joint.

Functional recovery following total ankle arthroplasty (TAA) is assessed with patient-reportedmetrics, but physical performance tests may allow for a more accurate assessment of patientfunction. We quantified correlations between patient-reported measures and physicalperformance tests in patients after TAA to determine the usefulness of physical performancetests in post-TAA assessment.

The lack of strong correlations between the 2 sets of metrics indicates that they provide different information about a patient’s recovery following TAA. Therefore, it is important to include both sets of metrics in post-TAA assessments to better understand operative success and functional recovery.

This study examined the effect of botulinum toxin upon plantar fasciitis through a randomized, controlled, and blinded trial.

Between 2012 and 2015, 50 patients presented with plantar fasciitis. Twenty-five patients each randomly received an IncobotulinumtoxinA (IBTA) or saline injection of their affected foot. Pre- and postinjection function and pain were graded with the Foot and Ankle Ability Measures (FAAM) and visual analog scale (VAS), respectively. All 50 study patients who randomly received either placebo or IBTA presented at 6 and 12 months after injection.

Compared with placebo saline injection, using IBTA to treat plantar fasciitis resulted in significantly better improvement in foot function and pain. IBTA also lessened the need for operative treatment of plantar fasciitis.

Patients’ perception of outcomes is not always defined by the absence of limitations/symptoms (resolution), but can also be characterized by behavioral adaptation and cognitive coping arising in cases with residual deficits. Patient-reported outcome measures (PROs) are designed to measure levels of function or symptoms, largely missing whether patients are coping with ongoing limitations. This study aimed to broaden the conventional definition of a “satisfactory” outcome following ankle reconstruction by comparing patient-reported outcomes of patients with and without residual symptoms and limitations.

Most patients reported positive outcomes, but few (15%) experienced resolution of all symptoms and limitations. Current PROs focus on achieving low levels of symptoms and limitations, but miss an important achievement when patients are brought to a level of residual deficits with which they can cope. Patients’ perceptions of satisfactory outcomes were not predicated on the resolution of all limitations; thus, the conventional definition of “satisfactory” outcomes should be expanded accordingly.

Repeated surgery can be a measure of failure of the primary surgery. Future reoperations might be avoided if the cause is recognized and procedures or devices modified accordingly. Reoperations result in costs to both patient and the health care system. This paper proposes a new classification system for reoperations in end-stage ankle arthritis, and analyzes reoperation rates for ankle joint replacement and arthrodesis surgeries from a multicenter database.

The new coding system presented here was reliable and may provide a more standardized, clinically useful framework for assessing reoperation rates and resource utilization than prior complication- and diagnosis-based classification systems, such as modifications of the Clavien Dindo System. Analyzing reoperations at the primary site may enable a better understanding of reasons for failure, and may therefore improve the outcomes of surgery in the future.

No reported study has compared clinical and radiologic outcomes between an all-inside arthroscopic modified Broström operation (MBO) and an open MBO. The purpose of this study was to compare clinical and radiologic outcomes of all-inside arthroscopic and open MBOs.

THe study found that there was no difference in the clinical or radiologic outcome between the all-inside arthroscopic MBO and open MBO for the treatment of lateral ankle instability at up to 1 year after surgery. An all-inside arthroscopic MBO should be considered carefully in patients who have lateral ankle instability.

The use of patient-reported outcomes continues to expand beyond the scope of clinical research to involve standard of care assessments across orthopedic practices. It is currently unclear how to interpret and apply this information in the daily care of patients in a foot and ankle clinic. We prospectively examined the relationship between preoperative patient-reported outcomes (PROMIS Physical Function, Pain Interference and Depression scores), determined minimal clinical important differences for these values, and assessed if these preoperative values were predictors of improvement after operative intervention.

Patient-reported outcomes (PROMIS) scores obtained preoperatively predicted improvement in foot and ankle surgery. Threshold levels in physical function, pain interference, and depression can be shared with patients as they decide whether surgery is a good option and helps place a numerical value on patient expectations. Physical function scores below 29.7 were likely to improve with surgery, whereas those patients with scores above 42 were unlikely to make gains in function. Patients with pain scores less than 55 were similarly unlikely to improve, whereas those with scores above 67 had clinically significant pain reduction postoperatively. Reported prognostic cutoff values help to provide guidance to both the surgeon and the patient and can aid in shared decision making for treatment.

Irreparable peroneus brevis tendon tears are uncommon, and there is scant evidence on which to base operative treatment. Options include tendon transfer, segmental resection with tenodesis to the peroneus longus tendon, and allograft reconstruction. However, the relative effectiveness of the latter 2 procedures in restoring peroneus brevis function has not been established.

Allograft reconstruction of a peroneus brevis tendon tear in this model substantially restored distal tension when the peroneal tendons and their antagonists were loaded to 50% and 100% of physiologic load. Tenodesis to the peroneus longus tendon did not effectively restore peroneus brevis tension under the tested conditions.

It is unclear whether proximal interphalangeal joint (PIPJ) resection or fusion leads to superior clinical outcome in patients undergoing hammertoe surgery. The purpose of this study was to prospectively evaluate a series of patients undergoing this surgery.

Our randomized controlled study did not show any clinical outcome difference between PIPJ fusion and PIPJ resection. Both procedures resulted in good to excellent outcome in pain and activity scores.

Although a variety of great toe implants have been tried in an attempt to maintain toe motion, the majority have failed with loosening, malalignment/dislocation, implant fragmentation and bone loss. In these cases, salvage to arthrodesis is more complicated and results in shortening of the ray or requires structural bone graft to reestablish length. This prospective study compared the efficacy and safety of this small (8/10 mm) hydrogel implant to the gold standard of a great toe arthrodesis for advanced-stage hallux rigidus.

A prospective, randomized (2:1), controlled, noninferiority clinical trial was performed to compare the safety and efficacy of a small synthetic cartilage bone implant to first MTP arthrodesis in patients with advanced-stage hallux rigidus. This study showed equivalent pain relief and functional outcomes. The synthetic implant was an excellent alternative to arthrodesis in patients who wished to maintain first MTP motion. The percentage of secondary surgical procedures was similar between groups. Less than 10% of the implant group required revision to arthrodesis at 2 years.

It has been previously demonstrated that radiographic severity of arthritis predicts outcome following knee replacement. In certain circumstances, patients may undergo arthroplasty without severe radiographic disease. An example may be the patient with significant chondral damage unsuccessfully treated with arthroscopy. This patient may proceed to joint replacement when their radiographs would not normally merit such intervention. We investigated whether these findings were also applicable to total ankle replacements (TARs).

Although this study does not explain all of the dissatisfaction in TAR, radiologic severity is an important factor that surgeons must consider when planning how best to treat their patients. There may be a different pathophysiology in this patient group that is not well served by arthroplasty.

Obesity is a known risk factor for the development of adult acquired flatfoot deformity (AAFD), but obesity’s effects on outcomes following AAFD reconstruction are unknown. The study hypothesized that obesity would negatively impact outcomes following joint-preserving stage II AAFD reconstruction.

This study found that although obese patients had significantly worse symptoms, overall health, and NRS pain scores preoperatively, the short-term clinical and radiographic outcomes of stage II AAFD reconstruction were similar for normal-weight, overweight, and obese patients. This suggests that joint-preserving reconstruction remains a viable alternative to fusion of the triple joint complex for the treatment of overweight and obese stage II AAFD patients.

Systems for classifying complications have been proposed for many surgical subspecialties. The goal of this systematic review was to analyze the number and frequency of different terms used to identify complications in total ankle arthroplasty. We hypothesized that this terminology would be highly variable, supporting a need for a standardized system of reporting.  The review showed that the reporting of complications and adverse outcomes for total ankle arthroplasty was highly variable. This lack of consistency impedes the accurate reporting and interpretation of data required for the development of cohesive, evidence-based treatment guidelines for end-stage ankle arthritis. Standardized reporting tools are urgently needed. This study presents a prototype worksheet for the standardized assessment and reporting of adverse events.

The prevalence of obesity in the United States is staggering. Currently, the effect of obesity on third-generation total ankle replacement (TAR) is unknown.  This study concluded that total ankle arthroplasty in obese patients was a relatively safe procedure. Although obese patients after TAR had lower functional outcome scores compared to their nonobese counterpart, they did experience significant functional and pain improvements at most recent follow-up.

This study was designed to compare the findings of noninvasive arterial testing in patients with and without diabetic foot pathology.

Combining the ABI (ankle brachial index) with TBI (toe brachial index) improved the ability to diagnose PAD (peripheral artery disease) in diabetic patients because the ABI has high specificity (low false positives) and the TBI has high sensitivity (low false negatives). The TBI was more reliable in patients with noncompressible arteries, medial artery calcinosis and/or neuropathy. Due to the relative incompressibility of calcified distal arteries in patients with DM, the ABI may be within normal limits in patients with PAD. This false negative result may lead surgeons to assume that normal perfusion is present.

Posttraumatic osteoarthritis (PTOA) can occur after intra-articular fracture despite anatomic fracture reduction. It has been hypothesized that an early inflammatory response after intra-articular injury could lead to irreversible cartilage damage that progresses to PTOA. Therefore, in addition to meticulous fracture reduction, it would be ideal to prevent this initial inflammatory response but little is known about the composition of the synovial environment after intra-articular fracture. The purpose of this work was to characterize the inflammatory cytokine and matrix metalloproteinase (MMP) composition in the synovial fluid (SF) of patients with acute intra-articular ankle fractures.

These data indicate that after intra-articular ankle fracture the SF exhibits a largely pro-inflammatory and extra-cellular matrix degrading environment similar to that described in idiopathic osteoarthritis. IL-6, IL-8, MMP-1, MMP-2, MMP-3, MMP-9, and MMP-10 were significantly elevated and may play a role in the development of PTOA.

Ligamentous injuries to the distal tibiofibular syndesmosis are predictive of long-term ankle dysfunction. Mild and moderate syndesmotic injuries are difficult to stratify, and the impact of syndesmosis injury on the magnitude and distribution of forces within the ankle joint during athletic activities is unknown. Considerable changes in ankle joint kinematics and contact mechanics may explain why moderate syndesmosis injuries take longer to heal and are more likely to develop long-term dysfunction and, potentially, ankle arthritis.
