Category: Ankle Introduction/Purpose: Treatment options for osteochondral lesion of the talus (OLT) have substantially increased over the last decade. There are a wide variety of surgical treatments for OLT, and good clinical results have been reported. However, treatment for OLT with large subchondral bone cysts remains under discussion. The combination of autologous bone grafting for subchondral bone cyst with fixation of articular cartilage would be the desirable procedure for the repair of the large subchondral cyst preserving the original cartilage with native structure and geometry. The purpose of this study is to evaluate the clinical outcome of autologous cancellous bone graft and fixation of cartilage fragment for OLT with large subchondral cysts. Methods: Patients comprised seven men and five women, aged 14–70 (mean 35.9) years. All OLTs included full-thickness articular cartilage, extended through subchondral bone and were associated with subchondral cysts. The mean size of the cysts was 9 ×8.6 ×12.3 mm on preoperative CT. Medial lesions were exposed through an oblique medial malleolar osteotomy; lateral lesions through expansion of an anterolateral arthroscopic portal. After refreshed the subchondral cyst, it was grafted with autologous cancellous bone from the distal tibial metaphysis, then cartilage fragments were fixed with nylon suture to surrounding cartilage. Postoperative MRI and CT scans were acquired for all patients at one year after surgery. Seven patients requested screw removal although none had symptoms. The screws were removed and simultaneous arthroscopic examination was performed at 1.5–2 years after surgery with the patients’ permission. The cartilage repair was assessed according to the criteria of the International Cartilage Repair Society (ICRS). Results: Functional outcome was evaluated at 25.3 (15–50) months after surgery. Mean American Orthopedic Foot and Ankle Society ankle-hindfoot outcome score improved from 65.7 to 92 (90–100) postoperatively, with 100% patient satisfaction. All follow-up CT scans showed that the grafts were well consolidated with the surrounding subchondral bone. On MRI one year after surgery, no scans showed any signs of osteochondral graft instability. The mean ICRS arthroscopic score from follow-up arthroscopy was 11.1 (8–12) points, and represented nearly normal cartilage. Conclusion: Our study demonstrated good results of autologous bone grafting in preserving articular cartilage in cases of symptomatic OLT with subchondral cysts. In seven cases, we performed follow-up arthroscopy at 1.5–2 years after primary operation and the chondral fragment showed a smooth surface and good stability. The technique of autologous bone grafting with chondral fragment fixation could be a promising option for treatment of OLT with subchondral cysts.

Abstract Background The aim of this study is to analyse the re-operation rate after surgical treatment of osteochondral lesions of the talus (OCLTs) in children and adolescents. Methods Between 2009 and 2019, 27 consecutive patients with a solitary OCLT (10 male, 17 female; mean age 16.9 ± 2.2 years; 8 idiopathic vs. 19 traumatic) received primary operative treatment (arthroscopy + bone marrow stimulation [BMS], n = 8; arthroscopy + retrograde drilling, n = 8; autologous chondrocyte implantation [ACI]/autologous bone grafting, n = 9; arthroscopy + BMS + retrograde drilling; n = 1; flake fixation, n = 1). Seventeen OCLTs were located at the medial and ten at the lateral talus. ‘Re-operation’ as the outcome measure was evaluated after a median follow-up of 42 months (range 6–117 months). Patients were further subdivided into groups A (re-operation, n = 7) and B (no re-operation, n = 20). Groups A and B were compared with respect to epidemiological, lesion- and therapy-related variables. Results Seven of 27 patients needed a re-operation (re-operation rate 25.9% after a median interval of 31 months [range 13–61 months]). The following operative techniques were initially used in these seven patients: arthroscopy + BMS n = 2, arthroscopy + retrograde drilling n = 4, ACI + autologous bone grafting n = 1. A comparison of group A with group B revealed different OCLT characteristics between both groups. The intraoperative findings according to the International Cartilage Repair Society (ICRS) classification revealed significantly more advanced cartilage damage in group B than in group A (p = 0.001). Conclusions We detected a re-operation rate of 25.9% after primary surgical OCLT treatment. Patients with re-operation had significantly lower ICRS classification stages compared to patients without re-operation.

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.
