In a study of patients with no or mild osteoarthritis who underwent arthroscopic partial meniscectomy, investigators found no clinically meaningful differences in patient satisfaction or clinical outcomes between patients who had traumatic vs. degenerative tears.
Researchers compared the postoperative outcomes at 5 years for patients who underwent arthroscopic partial meniscectomy with no or mild OA for degenerative tears (115 patients) and those with traumatic tears (143 patients). The five-point Likert scale was used to measure patient satisfaction. The KOOS and WOMAC were used to measure functional outcomes. Factors correlated with patient-reported satisfaction at 5 years postoperatively were determined with univariate and multivariate regression analyses.
Results showed the satisfaction rate in patients with traumatic tears was 68.5% and was 71.3% in patients with degenerative tears. There was a significant association between patient satisfaction and functional outcomes.
At the final follow-up, 43 patients with degenerative tears had OA progression to Kellgren-Lawrence grade 2 or grade 3; however, 24 patients had symptomatic knees. According to results of a multivariate regression analysis, independent factors for patient dissatisfaction included female sex, BMI greater than 30 kg/m2, lateral meniscal tears and OA progression to Kellgren-Lawrence grade 2 or greater.
No significant differences were seen at the final evaluation between groups with regard to pain scores, WOMAC scores and KOOS scores for pain, symptoms or sports/recreation. Patients with degenerative tears had significantly higher activities for daily living subscores and quality of life subscores than patients with traumatic tears; however, the differences were not clinically meaningful. – by Monica Jaramillo
