[Arthroscopic meniscectomy in anterior cruciate ligament deficient knees].

Results of 107 meniscectomies in 100 patients with long-lasting ACL deficiency are presented. Meniscectomy aggravates symptoms of ACL deficiency, worsening function of the knee. Bucket handle tear was observed most often--45 cases (36 displaced ones). The patients were reevaluated 3 years after surgery on an average using Tegner scale and pivot shift test. Tegner scale assessment rendered 62 per cent of excellent and good results, 32 per cent fair and poor results. Pivot shift was found in 21 patients prior to meniscectomy and in 37 patients at the follow-up examination; 18 patients were directed for ACL reconstruction. Arthroscopic meniscectomy in ACL deficient knee in most of the cases does not impair knee function if the activity level required is low. Evident pivot shift test, tear of the posterior horn of the medial meniscus and chondromalacia patellae are among unfavorable prognostic signs.
