[Postoperative evaluation of osteochondrosis dissecans of the talus with special reference to medial malleolar osteotomy].

Abstract

58 out of 69 patients after open operation for osteochondritis dissecans (OD) of the upper ankle joint were reexamined retrospectively. In 44 cases the medial talar edge was concerned, in 15 the lateral one. Pain in activity resisting conservative treatment led to the operations. 31 excisions, 16 drillings, 10 autogenous bone graftings (2 external) and 2 diagnostic arthrotomies had been carried out. Medial malleolar osteotomy had to be performed in 22 cases, mainly concerning excisions and graftings to maintain sufficient survey of the lesion. Follow-up examination took place an average 67 months postoperatively. The results were obtained through a new scoring system with special regard to subjective and clinical criteria. 13 excellent, 29 good, 10 fair and 7 bad results were obtained. Results depended mainly on operative approach, location of the lesion and in lateral OD time of operation. Medial malleolar osteotomy frequently led to local osteoarthritis and less favourable clinical findings. No significant difference could be realized for size of the lesion and the applied operative technique. Stage and age at time of operation did not clearly influence the outcome. The indication for operation must be made dependant on individual complaints. Even in the era of arthroscopy medial malleolar osteotomy sometimes is necessary, but goes along with higher morbidity and worse prognosis. Operations have to be carried out according to stage and followed by proper rehabilitation to render proper assessment. Lateral lesions result from sprains and should be operated early.
