Abstract
Purpose
The purpose of this study was to compare clinical and radiological outcomes of transtibial pullout technique and partial meniscectomy, and to establish prognostic factors in middle-aged patients with mild knee osteoarthritis.
Methods
A comparative case–control analysis was conducted. 65 patients between 40 and 60 years of age were included into two groups: 30 patients who underwent transtibial pullout technique (group 1) and 35 patients who underwent partial meniscectomy (group 2). Mean follow-up was set at 27.2 months. Primary clinical outcomes included Knee injury and Osteoarthritis Outcome Score and Lysholm Knee Questionnare. Preoperative MRI and intraoperative arthroscopic findings were recorded. The correlation between these findings and patient-reported subjective outcome were assessed.
Results
The transtibial pullout group exhibited significantly greater improvement in clinical outcomes. A univariate model revealed that the presence of preoperative meniscal extrusion, body mass index (> 30), osteochondral defect, and female gender were predictors of poor clinical outcome. Multivariate regression analysis showed meniscal extrusion and osteochondral defect as significant prognostic factors for both study groups.
Conclusion
Medial meniscus root repair leads to significantly improved clinical outcomes compared to partial meniscectomy in middle-aged patients with mild knee osteoarthritis. Presence of meniscal extrusion, osteochondral defect, BMI > 30, and female gender were deemed as predictors of poor postoperative patient-reported outcome.
Level of Evidence
III therapeutic case–control study.
