The treatment of open, traumatic intraarticular injuries to the metatarsophalangeal joint with severe articular comminution and cartilage defect of metatarsal head is a challenge to the foot surgeon. We report the joint reconstruction treating the injured joint by autogenic costal osteochondral graft with satisfactory outcome.

Freiberg disease is a osteochondrosis of the lesser metatarsal heads. Various surgical treatment have been recommanded including joint debridement and metatarsal head reshaping, metatarsal dorsal wedge osteotomy, metatarsal head excision and joint arthroplasty. Autogenous osteochondral graft for the treatment of Freiberg disease is an effective restorative procedure that provides early range of motion exercise, weight bearing, and reduces other morbidity. We report a case of late stage Freiberg disease treated with arthrotomy, removal of loose body and autogenous osteochondral graft.

Purpose: Osteochondral lesion of the talus (OLT) has traditionally been treated using an autologous osteochondral graft via the medial malleolar approach. Here, we compare the traditional method with the anterior arthrotomy approach. Materials and Methods: Between January 2005 and June 2015, 24 cases of patients who received autologus osteochondral graft for OLT and with at least 2 years of follow-up were evaluated. They were divided into two groups; one group receiving autologous osteochondral graft via the medial malleolar osteotomy approach (group 1, n=9) and another group via the anterior arthrotomy approach (group 2, n=15). The clinical outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) score. Results: In all cases, the size of the subchondral cyst of the talus decreased, if not disappeared on the final follow-up radiograph. All osteochondral grafts were united. The mean AOFAS score increased from 61.5 preoperatively to 84.9 at the final follow-up. The mean AOFAS score of group 1 increased from 60.3 preoperatively to 78.0 (p=0.007) at the final follow-up, and the mean AOFAS score of group 2 also increased from 62.2 to 89.1 (p=0.006). The AOFAS score was statistically better in group 2 than in group 1 (p=0.034) at the final follow-up. Conclusion: Autologous osteochondral graft of the OLT yields satisfactory radiologic and clinical outcomes. Especially, better clinical outcome was observed in the group using the anterior arthrotomy approach (group 2) than in the group using the medial malleolar osteotomy approach (group 1).

Purpose: The purpose of this study is to assess the results of the autologous osteochondral grafting harvested from medial side of talus for relatively large osteochondral lesion of the medial talar dome. Materials and Methods: From October 2004 to September 2005, 12 patients with osteochondral lesion measured more than 10 mm in axial MRI who were followed up more than 1 year after operation were analyzed. We evaluated postoperative symptoms by Mann and Reynolds scale, morbidity of donor site, and compared the range of both ankle motion. We also evaluated the union at the medial malleolar osteotomy site, trabecular connection between the grafted osteochondral mass and talus, irregularity of the articular surface in lesion. Results: Clinical results were rated as excellent in 4, good in 7, fair in 1. The mean angle of the total range of motion in affected ankle was decreased by 3 degrees compared to that in unaffected ankle. We did not observe abnormal findings at donor site. The osteotomized bone was united at mean 9 weeks (range, 8-12 weeks). We observed trabecular connection between grafted osteochondral mass and talus at mean 14 weeks (range, 12-16 weeks). We also observed irregular articular surface in osteochondral lesions in 6, smooth articular surface in 6. Conclusion: The local autologous osteochondral graft for relatively large osteochondral lesion of the medial talar dome is useful operative method with advantages of wide operative field, low morbidity of donor site, and high satisfaction rate.

Several methods to resurface the lost cartilage of the knee have been used, multiple drilling, microfracture, abrasion arthroplasty Resurfaced cartilages resulting from above techniques are mostly fibrocartilage. Autologous osteochondral graft transfer and autologous chondrocyte transfer are known to resurface the lost cartilage with mostly hyaline cartilage. This article reviews basic researches, indications, operative technique, and clinical results of autologous osteochondral graft transfer.

Purpose: The purpose of this study is to review clinical and radiologic changes after arthroscopic operation without bone graft for osteochondral lesion with subchondral cyst on the talus. And we compared the results with those without cyst. Radiologic changes were also observed. Materials and Methods: Arthroscopic microfrature or abrasion arthroplasty was performed on 10 caeses of osteochondral lesions with subchondral cyst and 20 cases without cysts. Preoperative and postoperative symptoms were evaluated by Ankle-Hind foot scale of AOFAS and the score of two groups were compared(t-Test : Paired Two Test for Means). Radiologic evaluation was performed after operation on patients with osteochondral lesion with cyst. Results: On patients of osteochondral lesion with subchondral cyst on talus, there was clinical improvement compared to the preoperative status and compared to patients without cysts(P=0.01) after arthroscopic operation. We could get increase of density and decrease of size of cystic lesion on plain film with time passage. Conclusion: We report 10 cases with osteochondral lesion with subchondral cyst on talus which resulted in clinical and radiological improvement after arthroscopic microfracture or abrasion arthroplasty without bone graft.

Microfracture as a reparative strategy is the treatment of choice for an osteochondral lesion of talus. Although the results of microfracture are generally excellent, at least 30% of patients who received microfracture have acute or chronic ankle pain with several or unknown causes. The most important factor for unsatisfactory outcome after microfracture is the size of the lesion. For failed osteochondral lesion of talus, the second options are autologous osteochondral graft, autologous chondrocyte implantation, or re-microfracture. In this article, we present the autologous chondrocyte implantation as a second procedure for failed microfracture and compare its clinical outcome with other methods based on a literature review.

Purpose: To evaluate clinical results of autologous osteochondral graft in osteochondral lesions of the talus. Materials and Methods: Twenty feet in twenty patients underwent osteochondral autologous transfer in the osteochondral lesions of the talus. Sixteen were men and four were women. The mean age was 40.8 years old. The mean follow up was 2 years 9 months. Eighteen cases were medial, one case was lateral and one case was both, respectively. The average duration of symptom was 4 years 3 months. AOFAS ankle/hindfoot score (AOFAS score), visual analogue scale (VAS), Lysholm knee score were evaluated preoperatively and at the final follow up. Results: Postoperative AOFAS score was 87.3 (range, 69-100), which was significantly improved from preoperative AOFAS score of 62.0 (p=0.000). Postoperative VAS was 2.9 (range, 0-7), which was significantly improved from preoperative VAS of 7.5 (p=0.000). Postoperative Lysholm knee score was 92.4 (range, 80-100). All osteotomy of medial malleolus was united by the 4th month after surgery. Postoperative VAS was conversely correlated with the follow up period (p=0.024). There was no complications associated with surgery. Conclusion: Autologous osteochondral grafts in osteochondral lesion of the talus demonstrated excellent results with a short-term follow up.
