Abstract: | The functions of the meniscus and subsequently the importance of meniscus preservation are well known. Thirty-one of 105 patients who underwent (closed) arthroscopic meniscus repair between 1982 and 1986 using an inside-out technique previously described were studied. Evaluations were based on The Hospital for Special Surgery knee rating system. Eighty-eight percent of the study population had a good-to-excellent outcome at an average 4.1 years follow-up. Most of these patients had no Fairbank changes on follow-up radiographs. Factors affecting outcome were analyzed. From this series, the at-risk factor for failure of meniscus repair is chronicity of injury (lasting longer than 2 weeks). Factors not noted to significantly influence results in this series include (a) age of the patient; (b) sex of the patient; (c) rim width up to 6 mm from the synovial meniscal junction; and (d) anterior cruciate ligament insufficiency. History of a reinjury and noncompliance with the postoperative rehabilitation protocol may also adversely influence results, but this is difficult to prove. |
