Dysplasia Epiphysealis Hemimelica

Dysplasia epiphysealis hemimelica (DEH), also known as Trevor’s disease, is a rare overgrowth of cartilage that commonly arises in the epiphyseal bone of children. We report a rare case of DEH originating from a talus accompanied by multiple intra-articular free bodies in a 7-year-old patient with ankle instability. After the primary surgery for free body removal and microfracture technique for the cartilage defects in the ankle joint, the free body recurred. Secondary surgery of arthroscopic free body removal with lateral ankle ligament repair succeeded in treating the patient, without further recurrence of the free body.

Lateral Ankle Ligament Reconstruction

Background: Anatomic lateral ankle ligament reconstruction has been proposed for patients with chronic ankle instability. A reliable approach is a reconstruction technique using an allograft and 2 fibular tunnels. A recently introduced approach that entails 1–fibular tunnel reconstruction might reduce the risk of intraoperative complications and ultimately improve patient outcome. Hypothesis: We hypothesized that both reconstruction techniques show similar ankle stability (joint laxity and stiffness) and are similar to the intact joint condition. Study Design: Controlled laboratory study. Methods: A total of 10 Thiel-conserved cadaveric ankles were divided into 2 groups and tested in 3 stages—intact, transected, and reconstructed lateral ankle ligaments—using either the 1– or the 2–fibular tunnel technique. To quantify stability in each stage, anterior drawer and talar tilt tests were performed in 0°, 10°, and 20° of plantarflexion (anterior drawer test) or dorsiflexion (talar tilt test). Bone displacements were measured using motion capture, from which laxity and stiffness were calculated together with applied forces. Finally, reconstructed ligaments were tested to failure in neutral position with a maximal applicable torque in inversion. A mixed linear model was used to describe and compare the outcomes. Results: When ankle stability of intact and reconstructed ligaments was compared, no significant difference was found between reconstruction techniques for any flexion angle. Also, no significant difference was found when the maximal applicable torque of the 1-tunnel technique (9.1 ± 4.4 N·m) was compared with the 2-tunnel technique (8.9 ± 4.8 N·m). Conclusion: Lateral ankle ligament reconstruction with an allograft using 1 fibular tunnel demonstrated similar biomechanical stability to the 2-tunnel approach. Clinical Relevance: Demonstrating similar stability in a cadaveric study and given the potential to reduce intraoperative complications, the 1–fibular tunnel approach should be considered a viable option for the surgical therapy of chronic ankle instability. Clinical randomized prospective trials are needed to determine the clinical outcome of the 1-tunnel approach.

Objectives: Lateral ankle ligament stabilization may be performed with concomitant arthroscopy. Arthroscopy has been shown to aid in the diagnosis of intra-articular defects that often accompany lateral ankle ligament injuries. This study compares the differences in cost, complications, newly diagnosed intra-articular defects, and reoperations among patients with ankle sprain/chronic instability who underwent lateral ankle ligament repair/reconstruction with or without concomitant arthroscopic procedures. Methods: Data was collected from the PearlDiver Technologies Humana dataset using CPT and ICD9/10 codes. Patients included in this study (n=2,188) had records of ankle sprain or ankle instability prior to or on the same day as one of two procedures: lateral ankle ligament repair (n=1,141) or lateral ankle ligament reconstruction (n=1,063). This population was subdivided by whether patients had records of arthroscopic procedure(s) on the same day as the ligament surgery. This yielded four groups: repair with arthroscopy (n=219), repair without arthroscopy (n=922), reconstruction with arthroscopy (n=325), reconstruction without arthroscopy (n=738). Cost, complications, newly diagnosed intra-articular defects, and reoperations were assessed. Results: Average cost per patient was higher for both arthroscopy groups: repair with arthroscopy ($6,207.78) versus repair without arthroscopy ($3,677.11; p < 0.0001); reconstruction with arthroscopy ($5,758.21) versus reconstruction without arthroscopy ($4,601.13; p = 0.0039). There was a significantly higher proportion of patients with complications in the reconstruction without arthroscopy group than in the reconstruction with arthroscopy group (7.59%, 4.31%; p = 0.0431), but the difference between repair groups was insignificant (p = 0.0626). The proportion of patients with newly diagnosed intra-articular defects was significantly higher in both arthroscopy groups: repair with arthroscopy (53.0%) versus repair without arthroscopy (35.6%; p < 0.0001); reconstruction with arthroscopy (56.0%) versus reconstruction without arthroscopy (39.8%; p < 0.0001). There was a significantly higher proportion of patients who underwent reoperation for intra-articular defects in the combined (repair plus reconstruction) arthroscopy group (7.18%) than in the combined non-arthroscopy groups (4.91%; p = 0.049). Most importantly, the average time until reoperation for intra-articular defects was significantly shorter in the combined arthroscopy group (271.923 days) than in the combined non-arthroscopy group (411.473 days; p = 0.024). Conclusion: Concomitant arthroscopy with lateral ankle ligament surgery is more expensive but does not appear to increase the overall complication rate and may allow surgeons to diagnose and treat more intra-articular pathology. Among patients requiring reoperation for intra-articular defects, the average time to reoperation was nearly 5 months shorter for patients receiving arthroscopy than for patients who did not receive arthroscopy.

Introduction. Lateral ankle instability represents a common orthopaedic diagnosis. Nonoperative treatment through focused physical therapy provides satisfactory results in most patients. However, some patients experience persistent chronic lateral ankle instability despite appropriate nonoperative treatment. These patients may require stabilization which can include primary lateral ligament reconstruction with a graft to restore ankle stability. Optimal post-operative rehabilitation of lateral ankle ligament reconstruction remains unknown, as surgeons vary in how long they immobilize their patients post-operatively. The aim of this review is to provide insight into early mobilization (EM) versus delayed mobilization (DM) post-operative protocols in patients undergoing primary lateral ankle ligament reconstructions to determine if an optimal evidence-based post-operative rehabilitation protocol exists in the literature. Methods. Following PRIMSA criteria, a systematic review/meta-analysis using the PubMed/Ovid Medline database was performed (10/11/1947-1/28/2020). Manuscripts that were duplicates, non-lateral ligament repair, biomechanical and non-English language were excluded. Protocols were reviewed and divided into two categories; early mobilization (within 3 weeks of surgery) and delayed mobilization (after 3 weeks of surgery). Functional outcome scores (AOFAS, Karlsson scores), radiographic measurements (anterior drawer, talar tilt) and complications evaluated using weighted mean differences (pre- and post-operative scores) and mixed-effect models. Results. After our search, we found 12 out of 1,574 studies that met the criteria for the final analysis, representing 399 patients undergoing lateral ankle reconstruction. Using weighted mean differences the DM group showed superior AOFAS functional scores compared to the EM group; 28.0 (5.5) vs. 26.3 (0.0) respectively, p < 0.001; although sample size was small. Conversely, no significant differences were found for Karlsson functional score (p = 0.246). With regards to radiographic outcome, no significant differences were observed; anterior drawer was p = 0.244 and talar tilt was p = 0.937. A meta-analysis using mixed-effects models confirmed these results, although heterogeneity was high. Conclusions. While there were some conflicting results, findings suggest that EM post-operative protocols for patients undergoing lateral ankle ligament reconstruction may not compromise functional outcomes or post-operative stability. Because heterogeneity was high, future studies are still needed to evaluate these protocols in less diverse patient groups and/or more consistent techniques for lateral ankle ligament reconstruction.

Category: Ankle Introduction/Purpose: There has a been recent increase in the use of the arthroscopic approach to lateral ankle ligament repair for chronic lateral ankle instability. However, the clinical outcomes of this technique are still unclear. The purpose of this systematic review was to evaluate the current studies on arthroscopic lateral ankle ligament repair for chronic lateral ankle instability. Our hypothesis was that arthroscopic lateral ligament repair would result in excellent outcomes with a low complication rate. Methods: A systematic search of MEDLINE, EMBASE and Cochrane Library databases, based on the PRISMA guidelines, was performed during August 2017 by 2 independent reviewers. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and percentage of patients who returned to sport at previous level were also evaluated. Results: Twelve studies for a total of 421 ankles were included; 92% of studies were LOE III or IV and the QOE in all studies was of poor or fair quality. The weighted mean preoperative AOFAS score improved from 59.6 to 95.0 at a mean follow-up of 14.8 months in 8 studies. Five studies utilized Karlsson-Peterson scores with mean postoperative score of 88.5 at a mean follow-up of 21.2 months. Three comparative studies were reported. The comparative studies showed similar clinical outcomes between arthroscopic and open procedures. The overall complication rate was 13.4% in the included studies. . Only 2 studies reported patients returning to sport and demonstrated that 100% of patients returned to sport at pre-injury level. Conclusion: The current systematic review demonstrated that arthroscopic lateral ankle ligament repair yields favorable clinical outcomes in the short-term. However, there is no clinical evidence to support the advantages of the arthroscopic procedure over the open procedure, and there is no long-term data currently available for the arthroscopic procedure. There was a relatively high complication rate associated with the arthroscopic procedures, with a 13.4% complication rate, although recent comparative studies demonstrated similar complication rates for both open and arthroscopic techniques.

Background: Multiple ankle pathologies have been found to coexist with chronic lateral ankle ligament instability, but their prevalence varies widely in the literature. The purpose of this study is to reexamine the prevalence of these associated pathologies and to determine their impact on reoperation rate. Methods: We retrospectively reviewed 382 cases of lateral ankle ligament repair/reconstruction between June 2006 and November 2016. Patient charts and radiograph reports were examined for the presence of any associated foot and ankle pathologies as well as clinical course. The effect of copathologies on reoperation rate was examined using binary logistic regression and the χ2 test. Results: We included a total of 99 cases. Copathologies included peroneal pathology (75/99, 75.8%), ankle impingement (40/99, 40.4%), and osteochondral lesion of the talus (17/99, 17.2%); 36.4% (36/99) had a low-lying muscle belly of peroneus brevis. The total reoperation rate was 12/92 (13.1%). It was lower in cases with peroneal pathology (8.7% vs 27.5%, P = .032). Conclusion: Peroneal pathology, ankle impingement, and osteochondral lesions were the most common associated copathologies in surgical patients with chronic lateral ankle ligament instability. The presence of peroneal pathology may lead to fewer reoperations, possibly as a result of a more comprehensive first-time surgical approach. Level of Evidence: Level III: Retrospective cohort

Category: Ankle Introduction/Purpose: Insufficient bony coverage surrounding the talus could cause considerable mechanical ankle instability, whereas excessive bony coverage could cause bone contusion at the time of injury and subsequent osteochondral lesions of the talus (OLT). This study aimed to investigate the relationship between radiographic lateral ankle instability and OLT in patients that sustained ankle inversion injuries. Methods: One-hundred-ninety-five patients (113 men and 83 women; mean age, 38.7 years; standard deviation, 8.8 years) with a history of ankle inversion injuries were included. All patients underwent ankle magnetic resonance imaging (MRI) and stress X-ray (varus stress and anterior drawer) examination. The tibiotalar tilt angle on varus stress X-ray, anterior translation of the talus on anterior-drawer lateral X-rays, bimalleolar tilt angle, and fibular position were radiographically determined. The anatomical grade of the lateral ankle ligament injury and the presence of OLTs were determined from MRI findings. Results: A greater lateral ankle ligament grade tends to increase the tibiotalar tilt angle (p=0.074), significantly affecting the anterior translation of the talus (p=0.036). The presence of radiographic lateral ankle instability (tibiotalar tilt angle =10°) showed opposite associations with the presence of OLT in the chi-square test (p=0.003). OLT was a negative significant factor (p=0.011) affecting the tibiotalar tilt angle in the multiple regression analysis (Table 1) and was negatively affected by the tibiotalar tilt angle (p=0.016) in the binary logistic regression analysis. Conclusion: This study showed an opposite association between lateral ankle instability and the development of OLT following ankle inversion injury. The role of bony predisposition in the development of sports injuries in the ankle should be considered and investigated further.
