Early Functional Outcomes and Complications of Tibial and/or Peroneal Sesamoidectomy Utilizing a Burr Through a Medial Approach.

BACKGROUND: Sesamoid pathology can lead to significant pain and disability both with activities of daily living and high-impact athletic movements. Sesamoidectomy is a widely used procedure for patients who fail conservative treatment measures. Traditional dorsal or plantar approaches for sesamoidectomy have shown to successfully alleviate pain, but complications were reported. A proposed alternative medial approach using a burr may provide many advantages compared with traditional approaches. This study presents patient outcomes and complications for this technique. METHODS: This was a retrospective chart review of patients undergoing sesamoidectomy (tibial, peroneal, or both) using a burr through a medial approach to the sesamoid metatarsal articulation. Data collected included patient demographics, radiographic analysis, and outcomes: Veterans Rand 12 Item Health Survey (VR-12), Foot and Ankle Ability Measure (FAAM), visual analog scale (VAS), patient satisfaction, and complications. RESULTS: Twenty-seven patients (29 feet) were included. The mean age was 38.4 years followed up for a mean of 30.9 months. VR-12 physical component improved from 35.98 ± 7.86 to 51.34 ± 8.01 (P < .001), FAAM ADL and sport improved from 58.33 ± 16.61 to 83.27 ± 18.28 (P < .001) and 26.37 ± 20.31 to 63.75 ± 29.74 (P < .001), respectively. Patient satisfaction with the treatment was 80.59% ± 27.06%. The overall complication rate was 11 (37.9%) whereas the overall reoperation rate was 4 (13.7%) of 29 feet. Complications included 1 arthrofibrosis, 1 flexor hallucis longus subacute rupture, and 1 asymptomatic hallux valgus. There were no sesamoid excision revisions. CONCLUSION: Sesamoidectomy using a medial approach with a burr provided significantly improved short-term functional outcomes, 80% patient satisfaction rate, with a relatively acceptable complications rate including 20% persistent pain. The medial approach is familiar to orthopaedic foot and ankle surgeons, provides adequate exposure, and eliminates the possibility of a painful plantar scar while avoiding disruption of the plantar plate, flexor hallucis brevis tendon, and ligamentous structures attached to the sesamoids. Larger studies with long-term follow-up from other centers are needed.

Isolated Talonavicular Arthrodesis as Treatment for Flexible Progressive Collapsing Foot Deformity: A Case Series.

Background: For the younger, more active patient with flexible symptomatic progressive collapsing foot deformity (PCFD), joint-sparing procedures may be preferred to preserve functional motion. Isolated talonavicular (TN) arthrodesis has been described for treatment of rigid and flexible PCFD for patients that are older and less active whose deformity is still correctable through the TN joint. The purpose of this study was to evaluate radiographic and clinical outcomes in patients with PCFD treated with isolated triplanar correction with a TN joint arthrodesis. Methods: Forty-nine patients (53 feet) with flexible PCFD underwent isolated TN arthrodesis. Weightbearing radiographs were performed pre- and postoperatively, and measurements included lateral talar-first metatarsal angle, calcaneal pitch, TN coverage angle, and the anteroposterior (AP) talar-first metatarsal angle. The Foot and Ankle Ability Measure (FAAM) and Veterans-Rand 12-Item Health Survey (VR-12) scores were also collected. Results: Thirty-five females and 14 males were evaluated with a mean age of 63 years, at an average follow-up of 41.3 months. Significant improvements were found radiographically. Lateral radiographs demonstrated improvements in lateral talar-first metatarsal angle from 25.2 degrees preoperatively to 9.5 degrees postoperatively (P < .001) and calcaneal pitch from 14.9 degrees preoperatively to 17.5 degrees postoperatively (P < .001). AP radiographs showed the TN coverage angle improving from 35.0 degrees to 4.9 degrees postoperatively (P < .001) and AP talar-first metatarsal angle improving from 17.3 degrees to 5.9 degrees postoperatively (P < .001). Clinical outcomes were improved in the FAAM pain score (48.6 to 39.2, P = .130), FAAM ADL score (53.8 to 69.2, P = .002), FAAM Sport score (29.5 to 40.7, P = .099), and the overall FAAM score (47.7 to 63.1, P = .006). Patient satisfaction with medical care was 85.2/100 postoperatively. Conclusion: Isolated TN arthrodesis is a viable surgical option for older, lower-demand patients with flexible PCFD. This study demonstrated significant improvements in radiographic alignment and FAAM scores. Comparative studies with other surgical procedures should be performed to determine which is the best technique for older, lower-demand patients with flexible PCFD. Level of Evidence: Level III, retrospective cohort study.

Outcomes of Surgically Treated Purely Ligamentous Stage II Lisfranc Injuries.

BACKGROUND: Low-energy stage II Lisfranc injuries are rare, and treatment can be operative or nonoperative based on a surgeon's assessment of midfoot stability. No previously published patient-reported outcome measures (PROMs) data for Lisfranc injuries isolates purely ligamentous stage II injuries. The purpose of this study was to analyze PROMs for patients who underwent operative management of stage II Lisfranc injuries. METHODS: Thirty-nine patients (39 feet) with confirmed Nunley-Vertullo stage II Lisfranc injuries between May 2012 and February 2022 were identified through a retrospective chart review. PROMs that were analyzed were the visual analog scale (VAS) pain scale, Veterans RAND 12-Item Health Survey (VR-12), Foot and Ankle Ability Measure (FAAM), and patient satisfaction. RESULTS: Thirty-two open reduction internal fixations (ORIFs) and 7 fusions were performed. The mean latest follow-up was 44.6 (range, 12-92) months. There were 2 complications (5%, 2/39) that required a revision procedure. Twenty-six patients (67%, 26/39) underwent secondary surgery to remove retained hardware. The mean time to hardware removal was 3.97 (range, 2.70-7.47) months. The overall mean patient satisfaction score with overall medical care including clinical visits and interactions with medical staff personnel was 93.6/100. All PROMs (VAS, VR-12, FAAM) demonstrated statistically significant improvement (P < .05) from preoperative (injury) values to latest follow-up postinjury values. CONCLUSION: Patients who were treated surgically with stage II purely ligamentous Lisfranc injuries via the methods used were found to mostly undergo hardware removal and have high levels of overall satisfaction with their process of medical care. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Male Gender and Competitive Athlete Status Are Associated With Better Outcomes Following Hip Arthroscopy In Patients With Global Acetabular Retroversion.

Purpose: To evaluate outcomes of hip arthroscopy in patients with global acetabular retroversion and to identify correlations between sex, radiographic measurements, athlete status, and return to play with patient-reported outcomes (PROs). Methods: Retrospective study of patients with global acetabular retroversion who underwent arthroscopic femoroacetabular impingement (FAI) surgery was performed. Global acetabular retroversion was defined by 3 criteria: the crossover sign, ischial spine sign, and posterior wall sign on an anteroposterior (AP) pelvic radiograph. Radiographs were used to measure lateral center edge angle, alpha angle, and anterior and posterior wall indices. Femoral version was measured with 3-dimensional computed tomography. Demographics included age, gender, athlete status, return to play, and reoperation. PROs included modified Harris Hip Score, Hip Outcome Score (HOS), Hip Disability and Osteoarthritis Outcome Score, visual analog scale (VAS), and Veterans RAND-12. Spearman correlation determined correlation with perioperative PROs. Generalized estimating equation determined independent predictors. Significance was set at P = .05. Results: From 2013 to 2019, 149 patients (65.0% female) with 160 hips with FAI and global acetabular retroversion underwent hip arthroscopy. Follow-up averaged 29.6 months. All PROs demonstrated significant improvement with the exception of the Veterans RAND-12 Mental. Female patients scored significantly lower on most postoperative PROs and had greater VAS scores (P = .0002-0.0402). A greater proportion of male subjects met the minimum clinically important difference for the modified Harris Hip Score (88.00% vs 78.79%) Low femoral version correlated with greater HOS ADL, HOS Sport, and Hip Disability and Osteoarthritis Outcome Score Sport scores (P = .0077-0.0177). Athletes reported lower preoperative VAS scores, and higher perioperative scores in multiple PROs (P = .0004-0.0486). Nine hips (5.63%) underwent reoperation. Conclusions: Patients with global acetabular retroversion and FAI undergoing hip arthroscopy report good outcomes at short-term follow-up. Male subjects and athletes had superior outcomes compared to female subjects and nonathletes. Radiographic measurements did not correlate with outcomes with exception of low femoral version. Athletes reported lower preoperative pain scores and greater postoperative PROs than nonathletes. Level of Evidence: Level IV, therapeutic case series.

Takedown of Ankle Fusions and Conversion to Total Ankle Replacements.

BACKGROUND: With ankle replacements gaining credibility, there is a small subset of patients who might benefit from a conversion of an ankle fusion to a replacement. The objective of this study is to present clinical and radiographic results of patients who had their ankle fusion converted to total ankle arthroplasty (TAA). METHODS: Patients presented to the senior author with ongoing ankle pain following fusion or increasing pain after a period of relative comfort after an ankle fusion. Outcomes were evaluated preoperatively and postoperatively with the Veterans Rand Health Survey (VR-12), Ankle Osteoarthritis Scale (AOS), and visual analog scale (VAS) pain scale. A patient satisfaction survey was also distributed. RESULTS: All ankle fusion conversions between April 2010 and December 2019 were included. Fifty-one patients (30 females) with the mean age of 62.6 (range, 37-83) years were followed. Mean follow-up was 4.2±2.3 (range, 2-11.5) years. Two patients were lost to follow-up (1 is deceased). Pre- and postoperative mean patient-reported outcome scores were all significantly different between groups except VR-12 mental subscale scores. VR-12 physical scores improved from 28.7±8.9 preoperatively to 38.9±9.9 (P < .001) postoperatively; VR-12 mental score was stable. AOS pain and disability subscales similarly improved: 55.9±24.4 to 27.9±25.4 (P < .001) and 61.7±21.1 to 31.1±25.7 (P < .001), respectively. VAS pain improved from a mean of 64.5±27.3 to 29.4±27.7 (P < .001). There was no tibiotalar dorsiflexion or plantarflexion with the ankle fusion. Initial postoperative visit revealed that average dorsiflexion was 10.9±5.93 degrees and average plantarflexion was 14.1±5.22 degrees. At the latest follow-up, dorsiflexion improved significantly to 15.5±6.33 degrees (P < .001), with no significant improvement in plantarflexion (P = .980). CONCLUSION: In this single-surgeon longitudinal study of 51 patients with a painful, malaligned, or nonhealed ankle fusion treated with an ankle replacement, we found highly satisfactory functional outcomes at an average of 4.2 years. Continued long-term follow-up will reveal whether the longevity of these replacements is comparable to primary replacements.

Arthroscopic Debridement Versus Refixation of the Acetabular Labrum Associated With Femoroacetabular Impingement: Updated Mean 7-Year Follow-up.

BACKGROUND: Short- and midterm follow-up studies suggest that arthroscopic labral refixation/preservation leads to superior outcomes compared with labral excision/debridement. PURPOSE: To update the previous early (16 months) and midterm (mean, 42 months) follow-up of this cohort, which reported better patient-reported outcome measures and lower failure rates in the repair/refixation group. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The authors identified patients who underwent labral debridement/focal labral excision during a period before the development of labral repair techniques. A consecutive group of patients within the labral debridement group thought to be repairable with the authors' current arthroscopic techniques were compared with a group of consecutive patients who underwent labral repair/refixation. In 46 hips, the labrum was focally excised/debrided consistent with pincer- or combined pincer- and cam-type impingement; in 54 hips, the labrum was repaired/refixed. Subjective outcomes were measured with the modified Harris Hip Score (mHHS), 12-Item Short Form Health Survey (SF-12), and visual analog scale (VAS) for pain preoperatively and postoperatively. RESULTS: The mean age was 34.0 years in the debridement group and 28.3 years in the repair/refixation group, with a mean follow-up of 7.3 years (range, 2-13.6 years). At the mean follow-up of 7.3 years, subjective outcomes were significantly improved (P < .01) for both groups compared with preoperative scores. The mHHS (P = .008), SF-12 score (P = .012), and VAS pain score (P = .002) were all significantly better for the repair/refixation group compared with the debridement group. Although most recent outcomes for both groups fell slightly at the mean follow-up of 7.3 years in comparison with the 16-month and 3.5-year follow-ups, these differences were not significant. However, the failure rate in the debridement group did get significantly worse (P = .014). Good to excellent results were 47.7% in the debridement group and 86.3% in the refixation group (P < .001), and failure rates were 30.4% (debridement) and 13% (refixation) (P = .033). There were 4 revisions in the debridement group and 3 revisions in the refixation group. CONCLUSION: Longer term, >7-year follow-up comparing focal labral excision/debridement with repair/refixation revealed better patient-reported outcomes and lower failure rates in the labral repair/refixation cohort. Additionally, despite an absolute decrease in patient-related outcome scoring and number of good/excellent results in both groups compared with the 3.5-year report, there was a significantly greater increase in failure rates over time for the excision/debridement group with better maintenance of good to excellent results in the repair/refixation group.

Femoral Head Allografts for Talar Body Defects.

BACKGROUND: Large structural bone deficits after a failed ankle arthroplasty or avascular necrosis (AVN) of the talus present a complex reconstruction challenge. The aim of this study was to report the results of patients undergoing an ankle arthrodesis or tibiotalocalcaneal fusion using a femoral head allograft (FHA). METHODS: All ankle and tibiotalocalcaneal fusions using FHA between February 2006 and January 2019 were included. Forty-four patients (45 ankles) with a mean follow-up of 42.8 months were studied. Males accounted for 58.1% (25/43 patients). All patients had either failure of primary or revision total ankle arthroplasty (TAA) or AVN of the talus. Pre- and postoperative Veterans RAND Health Survey (VR-12), Foot and Ankle Ability Measure (FAAM), Ankle Osteoarthritis Scale (AOS) and visual analog scale (VAS) for pain scores were obtained. A patient satisfaction survey was distributed postoperatively and results were tabulated. RESULTS: Preoperatively to postoperatively, the VR-12 Mental score remained essentially unchanged (P = .752) and the VR-12 Physical score improved (P = .007); the FAAM Activities of Daily Living (ADL) and Sport scores improved (P < .001); the AOS Pain and Disability scores improved (P < .001); and the man VAS score improved (P < .001). The overall satisfaction rate was 78.6 on a 100-point scale. At an average of 18.7 weeks, 90.7% of the ankles were substantially fused. Five patients went on to nonunions and revision surgery. CONCLUSION: The use of FHA to treat talar defects was a viable option. In this complex patient population, the arthrodesis rate was high at 89% with very positive patient-reported outcome scores. LEVEL OF EVIDENCE: Level IV, case series.

Retrospective Data Collection of Distal Interphalangeal Joint Fusion With X Fuse Superelastic Implant.

Purpose: Arthrodesis of the distal interphalangeal joint of the fingers and interphalangeal joint of the thumb is a common procedure for multiple diagnoses. The purpose of this study was to evaluate fusion rates and complications in patients who have been previously implanted with an X Fuse superelastic implant (Stryker). Methods: All patients who underwent distal interphalangeal and/or thumb interphalangeal joint fusion between June 2013 and May 2019 were included by the senior author. A chart review was used to note demographics; hand dominance; and medical and surgical history, including complications, comorbidities, clinical recovery, absence of pain, and functional use. Pre- and postoperative radiographs were evaluated for angular deformity, postoperative correction of that deformity, boney consolidation, and tine cutout. Results: Fifty-three patients (60 fingers; 43 women and 10 men) with a mean age of 62.6 years were included. The surgical diagnoses included hereditary osteoarthritis in 45 patients, rheumatoid arthritis in 4, psoriatic arthritis in 1, swan or mallet fingers in 5, ulnar motor loss instability in 2, and trauma or a fracture in 3. For X Fuse, an implant angle of 0° was used in 51 cases, whereas 15° was used in 9 cases. Bone consolidation was observed in all but 1 patient at an average time of 9.7 weeks (range 4.1-17.6 weeks). The X Fuse superelastic implant in small bones demonstrated minimal complications and a 98% (59/60) fusion rate. Conclusions: The X Fuse superelastic implant produced a reliable fusion, with no implant prominence and a 1.7% (1/60) rate of hardware removal. Type of study/level of evidence: Therapeutic IV.

Management of Ankle Arthritis After Severe Ankle Trauma.

OBJECTIVES: There are still unanswered questions about the best treatment options for ankle arthritis after severe lower leg trauma. This study compared results in outcomes and complications for 3 groups. DESIGN: Retrospective cohort study case-control study. SETTING: Single institution. PATIENTS: Three groups of 100 surgeries. INTERVENTION: Patients underwent an ankle fusion using anterior plate, total ankle arthroplasty (TAA) for primary osteoarthritis (OA), or a TAA for post-traumatic arthritis (PTA). MAIN OUTCOME MEASUREMENTS: Veterans Rand 12-Item Health Survey (VR-12), Ankle Osteoarthritis Scale, Visual Analog Pain Scale, and the American Orthopaedic Foot and Ankle Society Hindfoot score were collected preoperatively and at subsequent postoperative appointments. A patient satisfaction survey was also distributed to each patient postoperatively. RESULTS: Although all scores improved from preoperative to latest postoperative, the total ankle for PTA consistently resulted in the best postoperative outcomes. Patient satisfaction survey indicated 26% of fusion, 55% of TAA-OA, and 63% of TAA-PTA experienced very good to excellent pain relief. The overall satisfaction was found to be 92.5% for the TAA-PTA patients, 90.5% for the TAA-OA patients, and 84% for the fusion patients. Revision surgeries included 2 from the TAA-OA group, 2 from the TAA-PTA group, and 1 fusion patient. CONCLUSIONS: Results of comparing 3 groups who underwent an ankle fusion or a TAA demonstrate improvement in pain (P < 0.001), physical quality of life (P < 0.001), and activity (P < 0.001) and resulted in a high level of patient satisfaction. LEVEL OF EVIDENCE: Level III. See Instructions for Authors for a complete description of levels of evidence.

Patient-Reported Outcomes and Early Complications After Synthetic Cartilage Device Implantation.

BACKGROUND: Previous Level I studies show promising results for the use of a hydrogel synthetic cartilage implant (SCI) for the treatment of hallux rigidus. A recent independent retrospective review has put those results into question, however. The purpose of this article is to report patient-reported outcomes and early complications using this implant so as to add to the paucity of data in the literature regarding this implant. METHODS: This was a retrospective chart review of patients undergoing hydrogel synthetic cartilage implant for the treatment of hallux rigidus from July 2017 to November 2018. Data collected included patient demographics, radiographic grading, and outcomes: Veterans Rand 12 Item Health Survey (VR-12), Foot and Ankle Ability Measure (FAAM), visual analog scale (VAS), patient satisfaction, and complications. Fifty-four patients (59 feet) with an average age of 57.6 (range, 39-78) years were analyzed. The average latest follow-up was 18.9 (range, 3-31.3) months. Body mass index was 26.7 (range, 18.7-35.2). None were diabetic and 5 were smokers. RESULTS: The mean outcome improvements were 6.5 points (VR-12 Physical), 17.2 points (FAAM ADL), 27.4 points (FAAM Sport), and 18.4 points (VAS) (P < .01 for each). Scores were significantly improved from preoperatively to most recent follow-up for FAAM ADL (71.0 vs 88.2 points), FAAM Sports (44.6 vs 72.0 points), and VAS (49.4 vs 31.0) (P < .01). Overall, 72.5% patients would definitely or probably have the operation again. Ten patients (18.5%) went on to have revision surgery. Of these, 7 patients were revised to an arthrodesis, and 1 metal hemiarthroplasty and 2 implants were removed because of infection. CONCLUSION: Synthetic cartilage implantation for the treatment of hallux rigidus demonstrated improved pain and outcome scores at short-term follow-up. Reoperation and conversion to fusion rates were comparable to prior studies. LEVEL OF EVIDENCE: Level IV, case series.
