Abstract
Purpose
1) to report the clinical and radiographic outcomes of meniscus repair procedures in patients age 60 or older and compare them to matched patients who were treated with meniscectomy, and 2) to identify procedural failures.
Methods and Materials
The study cohort included patients over 60 years of age who underwent meniscus repair at a single medical institution (Mayo Clinic, Rochester, MN, USA). Medical records were reviewed to obtain demographic information, clinical history, physical exam findings, imaging details, and treatment details. The study cohort were matched by age (within 5 years), sex, BMI (within 5 years), and tear location (medial or lateral) with a comparative cohort. All patients were interviewed and completed a questionnaire comprising of IKDC (International Knee Documentation Committee Subjective Knee Form), KOOS and the Lysholm Knee Scoring Scale.
Results
81 patients (52 F: 29 M; 81 total knees) over the age of 60 with meniscus tears were included with a mean follow-up duration of 42.2 (±23.6) months. Mean age was 64.5 ( 4.4) years. Most knees had a tear of the medial meniscus (72.8%), while the lateral meniscus was torn in 27.2% of cases. In the majority of tears involved the meniscus root (56.8%), followed by the posterior horn (34.6%), and the mid-body (8.6%). At follow-up, the IKDC Subjective Knee Form Score was 78.9 ± 13.4 in the repair group and 56.0 (±15.4) in the meniscectomy group, the KOOS Knee Injury and Osteoarthritis Outcome Score 86.6 (±11.9) and 61.7 (±16.2) and the Lysholm Score 88.3 (±13.3) and 68.7 (±15.2) respectively. All scores were significantly superior in the repair group compared to the meniscectomy group (P < .001).
Conclusion
Meniscus repair provides superior clinical results at mean follow up of 42.2 months compared to partial meniscectomy. Meniscus repair should be considered when indicated even in patients at or over the age of 60.
