Surgical outcomes after arthroscopic partial meniscectomy

J Am Acad Orthop Surg. 2007 Nov;15(11):647-53. doi: 10.5435/00124635-200711000-00003.


Much research has been done to determine clinical and demographic variables associated with outcomes from arthroscopic partial meniscectomy for meniscal tears. We undertook a review of the literature to determine trends regarding outcomes from this procedure. Independent variables were analyzed for associations with outcome, and outcome measures and methods of statistical analysis were reviewed. Results of these studies demonstrate that patient age and sex had no significant association with any clinical or radiographic outcome variables at 8.5, 12, and 15 years. Patients with flap tears had slower return to sports and more revisions than did those with bucket handle tears. Osteoarthritis progressed more after medial partial meniscectomy in patients older than age 40 years than in younger patients. No statistically significant difference in medial versus lateral meniscectomy overall was shown. The best radiographic results in patients who underwent medial meniscectomy occurred in valgus knees compared with varus knees. Increased Modified Outerbridge cartilage scores at the time of surgery correlated with poorer physical results at 12 years.
