title: [Partial versus total meniscectomy. A prospective, randomized study].
abstract: Two hundred patients with a meniscus lesion were peroperatively allocated to partial or total meniscectomy. The results were compared at one year and at 6.3-9.8 years (median 7.8). After one year, more patients with partial meniscectomy (90%) than with total meniscectomy (80%) had no complaints (p = 0.029). At the late review these figures were 62% and 52% respectively (p = 0.18). However, patients with partial meniscectomy had the highest functional scores. In five percent knee joint function had improved and in 35% deteriorated, in the latter group without detectable difference between partial and total meniscectomy. The incidence of lateral laxity rose from eight to 47%, most frequently seen after total meniscectomy. During the observation period radiological signs of knee joint degeneration changed from solely joint line narrowing into additional ridge formation and flattening of the femoral condyle, but unrelated to whether partial or total meniscectomy had been performed. Following partial meniscectomy posterior horn lesions had the poorest functional outcome, but only if more than one third of the meniscal surface had been removed. The amount of meniscal tissue excised was inversely correlated to the level of knee joint function except in bucket handle lesions treated with partial meniscectomy. These lesions had the largest areas of meniscal tissue removed, but higher functional scores than posterior horn lesions. Preservation of the peripheral rim of the meniscus following partial meniscectomy was essential for the functional outcome after surgery.
