FAI January 2017 Podcast: Treatment of Plantar Fasciitis with Botulinum Toxin: A Randomized, Controlled Study

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.

FAI December 2016 Podcast: Symptom Resolution and Patient-Perceived Recovery Following Ankle Arthroplasty and Arthrodesis

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.

FAI November 2016 Podcast: A Coding System for Reoperations Following Total Ankle Replacement and Ankle Arthrodesis

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.

FAI October 2016 Podcast: Comparison of All-Inside Arthroscopic and Open Techniques for the Modified Broström Procedure for Ankle Instability

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.

FAI September 2016 Podcast: Preoperative PROMIS Scores Predict Postoperative Success in Foot and Ankle Patients

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.

FAI August 2016 Podcast: Effectiveness of Allograft Reconstruction vs Tenodesis for Irreparable Peroneus Brevis Tears: A Cadaveric Model

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.

FAI July 2016 Podcast: Long-term Follow-up of a Randomized Controlled Trial Comparing Scarf to Chevron Osteotomy in Hallux Valgus Correction

Hallux valgus is one of the most common foot deformities. This long-term follow-up study compared the results of 2 widely used operative treatments for hallux valgus: the scarf and chevron osteotomy.

Both techniques showed similar results after 2 years of follow-up. At 14 years of follow-up, neither technique was superior in preventing recurrence.

FAI June 2016 Podcast: Lesser Toe PIP Joint Resection Versus PIP Joint Fusion: A Randomized Clinical Trial

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.

FAI May 2016 Podcast: Prospective, Randomized, Multi-centered Clinical Trial Assessing Safety and Efficacy of a Synthetic Cartilage Implant Versus First Metatarsophalangeal Arthrodesis in Advanced Hallux Rigidus

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.

FAI April 2016 Podcast: Radiographic Severity of Arthritis Affects Functional Outcome in Total Ankle Replacement (TAR)

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.

FAI March 2016 Podcast: Effect of Obesity on Clinical and Radiographic Outcomes Following Reconstruction of Stage II Adult Acquired Flatfoot Deformity

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.

FAI February 2016 Podcast: Inconsistency in the Reporting of Adverse Events in Total Ankle Arthroplasty: A Systematic Review of the Literature

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.

FAI January 2016 Podcast: Effect of Obesity on Total Ankle Arthroplasty Outcomes

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.

FAI December 2015 Podcast: Non-Invasive Arterial Testing in Patients with Diabetes: a Guide for Foot and Ankle Surgeons

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.

FAI November 2015 Podcast: Inflammatory Cytokines and Matrix Metalloproteinases in the Synovial Fluid after Intra-Articular Ankle Fracture

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.
