  • Purpose: To evaluate the results of mosaicplasty and microfracture after surgical treatments for symptomatic osteochondral lesion of talus (OLT) by second-look arthroscopy. Materials and Methods: 7 cases of mosaicplasty and 7 cases of microfracture were reviewed who undertook second-look arthroscopy at 6 months or one year after undertaking mosaicplasty or microfracture for OLT between December 2004 and October 2005. The mean age at first operation was 43.6 years (Range, 20-59) (Mosaicplasty; 43.9 years, Microfracture; 43.4 years). The mean size of cartilage defect was $15.0{\times}7.7\;mm$ in mosaicplasty and $7.1{\times}6.6\;mm$ in microfracture. Clinical outcomes were evaluated by Freiburg ankle score. Cartilage healing state was evaluated by Insall's classification for chondromalasia during second-look arthroscopy. Results: By the Freiburg ankle score, 9 ankles (6 in mosaicplasty, 3 in microfracture) had excellent and 5 (1 in mosaicplasty, 4 in microfracture) had good results at the times of second-look arthroscopy. By Insall's classification, consistency of the osteochondral grafts and congruity between grafts and native cartilage (Grade I) were shown in 9 (6 ankles in mosaicplasty, 3 ankles in microfracture), a fissuring (Grade II) in one ankle of mosaicplasty, a fasciculation (Grade III) in one ankle of microfracture, and partial exposure of subchondral bone (Grade IV) in 3 ankles of microfractures. Conclusion: Mosaicplasty was more excellent in consistency and hardness of cartilage than microfracture. In some cases of microfracture, cartilage healing was incomplete at 6 months postoperatively, so second-look arthroscopy is necessary to identify. If incomplete cartilage healing was shown, additional procedure such as microfracture or mosaicplasty was needed.

  • Purpose: We present our experience about the clinical aspect and treatment modalities of ostechondritis dissecans of the talus. Material and Method: This study included 35 patients, 38 cases diagnosed as ostechondritis dissecans of the talus that were proved by clinical and radiologic finding. The methods of treatment were conservative (2 cases), multiple drilling (1 case), excision (1 case), excision, curettage & multiple drilling (23 cases), curettage & bone peg fixation (2 cases), curettage & bone graft (2 cases), and autogenous osteochondral transfer(Mosaicplasty) (7 cases). Results: Of the 38 cases, 30 cases were associated with a history of trauma (17 cases of medial lesion, 13 cases of lateral lesion), and 9 cases of which had major trauma history and 21 cases, minor repetitive trauma history. According to O'Farrel grading system, 21 cases (55%) had good results, 11 cases (29%) had fair results, and 6 cases (16%) had poor results. Of the medial lesion 16 cases had good results, 6 cases, fair results, and 2 cases, poor results. Of the lateral lesion 5 cases had good results, 5 cases, fair results, and 4 cases, poor results. Conclusion: There were fair or good results in 84% of patients with surgical treatment. Curettage and multiple drilling reveals a good result in medial lesion in grade I, II, III and lateral lesion in grade I, II. Autogenous osteochondral transfer(Mosaicplasty) is considered for the cases in grade III, IV(medial and lateral), lesion exceeds 1Cm of size and poor result with another treatment modality.

  • 슬관절의 연골 결손에 대한 치료로 여러가지 방법이 시행되어 왔는데, 기존의 방법들은 치 유된 결손 부위가 섬유연골로 덮히는 것으로 알려져 있다. 최근 시행되는 자가 골연골 이식술과 자가 연골세포 이식술은 결손 부위가 대부분 초자연골로 덮힌다고 알려져 있다. 이 논문에서는 자가 골연골 이식술의 기초적 연구, 적응증, 수술 기법, 수술 후 결과를 기술하고자 한다.

  • 최근에 스포츠 손상이 증가하고 관절경을 이용한 치료가 발전하면서 조기에 더 적극적인 치료를 하는 추세이다. 또한 방사선 소견에 비하여 관절경하에서는 연골이 불안정하거나 분리되어 있는 경우도 있으므로 기존의 수술 적응증보다는 좀 더 광범위하게 관절경 검사 및 수술적 치료가 요구된다고 생각한다. 치료 방법을 하면 $1.5cm^2$ 이하의 병변을 가진 50세 이하의 환자는 관절경을 이용하여 변연 절제술, 연골하 천공, 연마, 미세 골절술, 소파술 등의 방법으로 치료할 수 있다. 같은 방법으로 50세 이상의 $3cm^2$ 이하의 병변을 가진 환자 중 mosaicplasty와 자가 연골 세포 이식술을 적용할 수 없는 환자에서 시도해볼 수 있다. $1.5\sim3cm^2$의 병변을 가진 50세 이하의 환자, 그전의 관절경적 치료로 실패한 경우에는 자가골 연골 이식 또는 자가 연골 세포 이식술을 이용하여 치료해야 한다. $3cm^2$ 이상의 병변을 가진 50세 이하의 환자는 자가 연골 세포 이식술이나 동종 골 연골 이식을 이용하여 치료하며, 50세 이상의 환자는 관절 고정술이나 족근 관절 인공치환술을 고려하는 것이 바람직하다.

  • Allograft arthroplasty is a promising cartilage-resurfacing technique. A 14-year-old horse was diagnosed with a medial femoral condyle subchondral bone cyst. Allografts were harvested from a young donor animal and implanted to fill the cyst cavity. A visual assessment of the surgical site was possible during follow-up arthroscopy. In addition to a desirable gliding surface and a good adaptation of the grafts, fibrillation of the cranial ligament of the medial meniscus was noted and debrided. The recipient horse became sound four months after follow-up surgery with a high level of owner satisfaction. In conclusion allograft transplantation is a promising technique for treating subchondral bone cysts.
