Abstract
PURPOSE: To determine which specific factors influence the improvements in function and pain at the first year following arthroscopic partial meniscectomy. METHODS: Between 2012 and 2013, patients who had arthroscopic partial meniscectomy were included (n = 201) and followed prospectively before surgery and at 12 months. Multivariable stepwise analysis included preoperative variables (age, gender, limb side, height, weight, body mass index, comorbidities, smoking, Tegner activity scale, Lysholm knee score, preceding injury and duration of preoperative symptoms) and arthroscopic findings (degree of cartilage lesions, medial or lateral meniscus involvement, type of meniscal tear and concomitant cruciate tear). The Lysholm clinical score at the last follow-up and the time interval for substantial pain relief was modelled as a function of the above predictor variables. RESULTS: At the last follow-up, the mean Lysholm score improved by 14.6 points (95 % CI 10.4-18.8, P < 0.001), from 68.0 ± 16.1 to 82.6 ± 19.6 points and 153 (76 %) patients declared they were satisfied to have had the operation. The mean time interval for substantial pain relief was 3.5 ± 1.5 months. Females and patients with lower preoperative Lysholm score were correlated with lower post-operative Lysholm score, while females and patients with lateral meniscal tears (compared to medial meniscal tears) were correlated with longer recovery. CONCLUSIONS: Arthroscopic partial meniscectomy improved pain and function at the first year post-operatively. Female gender, lateral meniscal tear and less favourable preoperative function were relatively correlated to worse post-operative function and longer rehabilitation time. LEVEL OF EVIDENCE: IV.
