BACKGROUND AND OBJECTIVEMeniscus transplantation has been performed for more than 20 years, with the goal of decreasing pain and improving function. This study was designed to determine the long-term functional outcomes and survivorship rates in a consecutive series of patients receiving meniscal transplants.
METHODSSubjects were 69 consecutive patients, 50 years of age or younger, seen between 1995 and 2005, receiving a total of 72 meniscus transplants. Of these surgeries, 44% were isolated meniscus transplantations, and 56% involveda concurrent or staged operative procedure. Outcomes deterrnined at follow-up examinations included physical exam findings, ratings using the International Knee Documentation Committee (IKDC) and the Cincinnati Knee Rating System. Postoperative imaging included radiographs and MRI.
RESULTSFor all transplants, the combined probability of survival was 85% at two years, 77% at five years, 45% at 10 years and 19% at 15 years. Repeat surgeries related to the feilure of transplants were performed in 37 cases, ranging in time from 0.2 to 3.5 years postoperatively. Of the 58 transplants available for long-term functional outcome, at 11.2 years, 26 failed and required later surgery. For all 58 survivors, significant improvements were found in pain, swelling, patient perception of overall knee condition, walking and stair climbing.
CONCLUSIONThis study of 69 patients undergoing meniscus transplant found the survival rates at 10 and 15 years to be 45% to 19%, respectively.
