Background: Subchondroplasty (SCP) is a relatively new procedure, developed in 2007 for the treatment of bone marrow lesions (BMLs), that has shown promising results in the knee through several different case series. The foot and ankle literature, however, is sparse, with only a few documented case reports or case series. At our institution, we have identified several patients with complications after this specific procedure. As a result, we report our case series of patients who developed talar avascular necrosis (AVN) after undergoing SCP. Methods: A retrospective review was performed of patients who underwent SCP for a talar BML at our facility or who were referred to our facility after undergoing SCP at an outside institution. Patients were included if they developed radiographic evidence of talar AVN after the procedure. Patient demographics, comorbidities, concomitant intraoperative procedures, complications, and subsequent interventions were reviewed. Results: Seven patients were identified as having radiographic evidence of talar AVN after SCP. Average time interval was 23 months postoperative from index procedure to radiographic confirmation of AVN. Two of the index procedures were performed at our institution, whereas 5 of the index procedures were performed at outside institutions and referred for further management. Three patients had documented risk factors for AVN before the SCP procedure. All 7 patients were symptomatic from the AVN. Conclusion: We identified 7 patients who went on to develop talar AVN after having undergone SCP. Level of Evidence: Level IV, case series.

Category: Ankle, Basic Sciences/Biologics Introduction/Purpose: Subchondroplasty® (SCP®) (Zimmer Holdings, Inc, Warsaw, IN) is a relatively new procedure that was developed in 2007 for the treatment of bone-marrow lesions (BMLs). It involves the injection of flowable nanocrystalline calcium phosphate (CaP) synthetic bone substitute into the BML using fluoroscopic-guidance, in order to promote healing and reinforce the effected region. Although a newer technique, SCP has been shown promising results in the knee through several different small case-series. The foot and ankle literature is sparser, with only a few documented case-reports or case-series. As a result, we wanted to report our small case-series of patients who underwent talar SCP and went on to develop avascular necrosis (AVN). Methods: A retrospective review was conducted of patients who underwent SCP for a talar BML at our facility or were referred to our facility after undergoing SCP at an outside institution. Patients who developed iatrogenic talar AVN postoperatively were included in the study. Patient characteristics, comorbidities, imaging, and need for further surgery was analyzed. Results: Four patients were identified who had previously undergone talar SCP and went on to develop iatrogenic talar AVN. Two patients had their original SCP performed at our facility, whereas the other two patients were referred from outside institutions. All four patients were symptomatic from their AVN. Two patients have undergone revision surgical intervention, while the other two patients are pending surgical intervention. Conclusion: This case-series is the first study, to our knowledge, to report iatrogenic talar AVN after undergoing SCP for talar BMLs. Although early studies in the Foot and Ankle literature are promising for use of this technology, these studies have been small and surgeons should be aware of this potential complication.

Context: Injections are commonly used by health care practitioners to treat foot and ankle injuries in athletes despite ongoing questions regarding efficacy and safety. Evidence Acquisition: An extensive literature review was performed through MEDLINE, Google Scholar, and EBSCOhost from database inception to 2021. Keywords searched were injections, athletes, sports, foot and ankle, corticosteroids, platelet-rich plasma, and placental tissue. Search results included articles written in the English language and encompassed reviews, case series, empirical studies, and basic science articles. Study Design: Clinical review. Level of Evidence: Level 4. Results: Corticosteroids, platelet-rich plasma/autologous blood, anesthetic, and placental tissue injections are commonly used in the treatment of foot and ankle injuries. Primary indications for injections in athletes include plantar fasciitis, Achilles tendinosis, isolated syndesmotic injury, and ankle impingement with varying clinical results. Conclusions: Despite promising results from limited case series and comparative studies, the data for safety and efficacy of injections for foot and ankle injuries in athletes remain inconclusive.

Abstract The aim of this study is to evaluate the results of patients underwent lateral open wedge calcaneus osteotomy with bony allograft augmentation combined with tibialis posterior and tibialis anterior tenodesis. Twenty-two patients underwent adult-acquired flatfoot deformity were retrospectively evaluated with a minimum 2-year follow-up. Radiographic preoperative and final comparison of tibio-calcaneal angle, talo–first metatarsal and calcaneal pitch angles have been performed. The Visual Analog Scale, American Orthopedic Foot and Ankle Score, the Foot and Ankle Disability Index and the Foot and Ankle Ability Measure were used for subjective and functional assessment. The instrumental range of motion has been also assessed at latest follow-up evaluation and compared with preoperative value. There was a significant improvement of final mean values of clinical scores (p < 0.001). Nineteen out of 22 (86.4%) patients resulted very satisfied or satisfied for the clinical result. There was a significant improvement of the radiographic parameters (p < 0.001). There were no differences between preoperative and final values of range of motion. One failure occurred 7 years after surgery. Adult-acquired flatfoot deformity correction demonstrated good mid-term results and low recurrence and complications rate. Level of evidence Level 4, retrospective case series.

Predictive Risk

Background: The incidence rate of venous thrombotic events (VTEs) following foot and ankle surgery is low. Currently, there is no consensus regarding postoperative prophylaxis or evidence to support risk stratification. Methods: A 2-part study assessing the incidence and factors for the development of VTE was conducted: (1) a retrospective observational cohort study of 22 486 adults to calculate the overall incidence following foot and/or ankle surgery from January 2008 to May 2011 and (2) a retrospective matched case-control study to identify risk factors for development of VTE postsurgery. One control per VTE case matched on age and sex was randomly selected from the remaining patients. Results: The overall incidence of VTE was 0.9%. Predictive risk factors in bivariate analyses included obesity, history of VTE, history of trauma, use of hormonal replacement or oral contraception therapy, anatomic location of surgery, procedure duration 60 minutes or more, general anesthesia, postoperative nonweightbearing immobilization greater than 2 weeks, and use of anticoagulation. When significant variables from bivariate analyses were placed into the multivariable regression model, 4 remained statistically significant: adjusted odds ratio (aOR) for obesity, 6.1; history of VTE, 15.7; use of hormone replacement therapy, 8.9; and postoperative nonweightbearing immobilization greater than 2 weeks, 9.0. The risk of VTE increased significantly with 3 or more risk factors ( P = .001). Conclusion: The overall low incidence of VTE following foot and ankle surgery does not support routine prophylaxis for all patients. Among patients with 3 or more risk factors, the use of chemoprophylaxis may be warranted. Level of Evidence: Level III, retrospective case series.

Objective: To assess postoperative clinical functional outcomes, based on the American Orthopaedic Foot & Ankle Society (AOFAS) score, of tendoscopies performed in the treatment of foot and ankle pathologies. Methods: Our comparative assessment used AOFAS scores obtained preoperatively and at early and late postoperative stages - 1 month and 6 to 12 months after surgery - of 14 patients with foot and ankle tendinopathies. These included peroneal tendon dislocation, peroneal tendonitis, and tearing of the peroneus longus or brevis, all treated with tendoscopy for peroneal reconstruction and tenorrhaphy. The AOFAS score was obtained by functional assessment during outpatient physical examination. We presented a descriptive analysis of cases, comparing scores over time through the Friedman test followed by Dunn’s test. The relationship between score variations and sex was assessed using the Mann-Whitney test; their comparison with age used Spearman’s linear correlation coefficient. Significance levels were 5%.Results: The AOFAS score showed important improvements such as preoperative scores of 56 and 67 followed by postoperative scores of 100 both in the early and late stages, supporting the efficacy and persistence of this treatment strategy. The p-value obtained after statistical analysis was <0.0001. Conclusion: We concluded that the treatment of foot and ankle comorbidities with tendoscopy, in addition to being less invasive, shows consistency and efficacy as demonstrated by the AOFAS score and functional assessment via postoperative physical examinations. AOFAS scores were increased and maintained at high levels in the postoperative period, demonstrating the efficacy of this procedure and the duration of treatment results.

Background: Patient-reported outcome measures are an increasingly important tool for assessing the impact of treatments orthopedic surgeons render. Despite their importance, they can present a burden. We examined the validity and utility of a computerized adaptive testing (CAT) method to reduce the number of questions on the Foot and Ankle Ability Measure (FAAM), a validated anatomy-specific outcome measure. Methods: A previously developed FAAM CAT system was applied to the responses of patients undergoing foot and ankle evaluation and treatment over a 3-year period (2017-2019). A total of 15 902 responses for the Activities of Daily Living (ADL) subscale and a total of 14 344 responses for the Sports subscale were analyzed. The accuracy of the CAT to replicate the full-form score was assessed. Results: The CAT system required 11 questions to be answered for the ADL subscale in 85.1% of cases (range, 11-12). The number of questions answered on the Sports subscale was 6 (range, 5-6) in 66.4% of cases. The mean difference between the full FAAM ADL subscale and CAT was 0.63 of a point. The mean difference between the FAAM Sports subscale and CAT was 0.65 of a point. Conclusion: The FAAM CAT was able to reduce the number of responses a patient would need to answer by nearly 50%, while still providing a valid outcome score. This measure can therefore be directly correlated with previously obtained full FAAM scores in addition to providing a foot/ankle-specific measure, which previously reported CAT systems are not able to do. Level of Evidence: Level IV, case series.

Category: Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) is gaining popularity as an alternative to ankle arthrodesis in the setting of end-stage ankle arthritis. However, compared to hip and knee arthroplasty, there is a relative dearth of evidence to support its use. This study assesses the quality of literature surrounding modern TAA designs. Methods: A search of all peer-reviewed, English-language journals was conducted to identify publications involving TAA. The initial search identified 444 articles published during 2006-2016. Of these, 182 were excluded because they were not clinical outcomes studies, 46 because the TAA implant was no longer available, and 15 because the primary outcome of the study was not related to TAA, leaving 201 articles for analysis. Results: No Level I studies were identified. Seventeen (8%) studies were Level II, 48 (24%) Level III, 128 (64%) Level IV, and 8 (4%) Level V. One hundred forty-three studies (71%) were retrospective in nature. Stratification by study design revealed 128 (64%) case series, 33 (16%) experimental cohort studies, 19 (10%) case-control studies, 13 (6%) observational cohort studies, and 8 (4%) case reports. The number of studies published each year steadily increased from 2006 to 2016. A total of 51% of TAA research was published in only two journals: Foot and Ankle International and the Journal of Bone and Joint Surgery. Publications from the United States accounted for 36% of total publications. The most published implant was the Scandinavian Total Ankle Replacement (Figure 1). Conclusion: While the number of TAA studies published each year has steadily increased since 2006, the quality of this research as measured by level of evidence remains suboptimal. This analysis highlights the need for continued improvement in methodology and development of robust prospective registries to advance our knowledge of TAA as a treatment for end-stage ankle arthritis.

Olecranon apophyseal nonunion is an elbow injury from overuse that affects adolescent athletes such as baseball pitchers who participate in overhead throwing sports. However, such injury is rare in collision sports. Here, we report two patients with this condition who are Judo athletes. The purpose of this report was to describe three elbows with olecranon apophyseal nonunion in two adolescent patients participating in Judo. This is a case series; the level of evidence is 4. Two 15-year-old patients were evaluated. One suffered from unilateral and the other from bilateral chronic posterior elbow pain. They were diagnosed with olecranon apophyseal nonunion, which was treated using internal fixation and bone grafting. Radiographic evidence of the apophyseal union was observed four months postsurgery. Two elbows were treated with tension band wiring, then they underwent hardware removal six months postsurgery. Both patients returned to their previous levels of activities six months postsurgery. Internal fixation using autologous bone grafting was a useful treatment for these Judo athletes with olecranon apophyseal nonunion.

Background: While traditional biological principles have suggested that fragments consisting of cartilage alone cannot be reaffixed to bone with expectable long-term healing, case reports of successful healing after fixation in younger patients indicate that this concept remains incompletely explored. Purpose: To evaluate the presenting features, techniques, healing rates, and clinical and radiological results in a cohort of pediatric and adolescent athletes who underwent fixation of traumatic chondral-only fragments in the knee. Study Design: Case series; Level of evidence, 4. Methods: Patient registries at 2 tertiary care children’s hospitals were reviewed to identify patients ≤18 years old who underwent fixation of a “chondral-only” fragment in the knee, defined as the inability to visualize the fragment on injury radiographs or discern bone on the articular portion of a fragment intraoperatively. The mechanism of injury, fragment features, fixation technique, and postoperative clinical course, including timing of sports clearance, healing on postoperative magnetic resonance imaging (MRI), and any complications or reoperations, were assessed. Results: Fifteen patients with a median age at surgery of 12.7 years (interquartile range [IQR], 11.7-14.2 years) and median follow-up of 12.0 months (IQR, 6.0-19.2 months) were analyzed. All patients sustained an acute knee injury before surgery. The injured sites, as assessed on MRI, were the patella (n = 6), trochlea (n = 5), and lateral femoral condyle (n = 4). The median fragment surface area was 492.0 mm2 (IQR, 400.0-787.5 mm2). Fixation with bioabsorbable implants was performed in all patients at a median of 1.6 weeks (IQR, 1.0-2.6 weeks) after the injury. One patient (7%) sustained a fall 8 weeks postoperatively, requiring secondary surgery for excision of a dislodged fragment, and 1 patient (7%) underwent unrelated patellar stabilization surgery 3.4 years postoperatively, at which time the fragment was found to be stable. MRI was performed in 9 of 14 patients with retained fragments (median, 12.0 months postoperatively), with 5 patients (56%) showing restoration of the cartilage contour and the resolution of subchondral edema; 2 patients showed thinning but intact cartilage, 1 had cartilage thickening, and 1 had subchondral edema, fissuring, and cystic changes. The median time to return to sports for all 15 patients was 26.0 weeks (IQR, 22.8-40.9 weeks), including 2 patients who required second surgery and returned to sports at 26.1 and 191.1 weeks. Conclusion: Fixation of traumatic chondral-only fragments using bioabsorbable implants may result in successful short-term healing in the majority of pediatric and adolescent athletes.

Background: 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. Methods: A retrospective review was performed on all patients that received perioperative ketorolac at the time of lateral malleolar, bimalleolar, and trimalleolar ankle ORIF by a single surgeon between 2010 and 2016 with minimum 4 months follow-up. Patients received 20 tablets of 10 mg ketorolac Q6 hours. Radiographs were evaluated independently by 2 blinded fellowship-trained orthopedic foot and ankle surgeons to assess for radiographic healing. A total of 281 patients were included, with a median age of 51 years and 138 males (47%). Statistical analysis consisted of a linear mixed-effects regression. Results: In all, 265/281 (94%) were clinically healed within 12 weeks and 261/281 (92%) were radiographically healed within 12 weeks. Within the group of patients that did not heal within 12 weeks, mean time to clinical healing was 16.9 weeks (range = 14-25 weeks), and mean time to radiographic healing was 17.1 weeks (range = 14-25 weeks). In patients taking ketorolac, there were no cases of nonunion in our series (n = 281) and no significant difference found between fracture patterns and healing or complications ( P = .500). Conclusions: 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. Level of Evidence: Level IV, case series.
