Functional outcome of medial meniscal posterior root repair with medial opening wedge osteotomy with early osteoarthritis and meniscal root tear: A prospective observational study

Objectives: A tear of the meniscus root is considered biomechanically equivalent to a complete meniscectomy. A plethora of management options have been devised, without a clear consensus. This study aims to evaluate the clinical outcomes of medial meniscus posterior root repair (MMPRR) performed in addition to a medial open wedge high tibial osteotomy (MOW-HTO), focusing on pain levels and functional scores in middle-aged patients in an Indian setting. Materials and Methods: A prospective observational study was conducted from April 2023 to September 2025 at a tertiary hospital. 11 patients with recent onset knee pain and radiologically confirmed medial meniscus posterior root tear (MMPRT) were included. Functional results were determined using the Visual Analog Scale (VAS) for pain, Lysholm score, and International Knee Documentation Committee (IKDC) score preoperatively, and at 3 months, 6 months, and 1 year postoperatively. Surgical repair involved the use of suture anchors and MOW-HTO fixed with a locking plate. Centralization sutures were used in cases with meniscus extrusion. Results: All patients showed clinically significant improvement in functional indices. IKDC scores improved from 51.1 ± 3.0 preoperatively to 67.1 ± 6.7 at 12 months. Lysholm score increased from 62.4 ± 1.5 to 79.4 ± 5.9, and VAS reduction was 1.8 ± 0.8 points from the preoperative baseline. No major complications were seen. Conclusion: Arthroscopic MMPRR, along with MOW-HTO, has shown good functional outcomes and can be considered for the management of patients with MMPRT. Correct patient selection is vital to achieve good results.
