Combined posterior incision and arthroscopic intra-articular repair of the meniscus. An examination of factors affecting healing

ABSTRACT: Using intra-articular techniques for meniscal repair, several factors associated with meniscal lesions were analyzed prospectively to determine their effects on healing of the repair. Although 260 medial or lateral meniscal repairs in 240 patients were done, 178 repairs in the 167 patients who were followed by post-operative arthroscopy or arthrography form the basis of this study. The results of the repairs were classified as healed, incompletely healed, or not healed. The av-erage duration of follow-up was 100 weeks (range, twenty-eight to 231 weeks). By arthrographic or arthroscopic criteria, 61.8 per cent of the menisci healed, 16.9 per cent healed incom-pletely, and 21.3 per cent did not heal. Ninety-two per cent of the menisci were categorized as clinically stable
