Abstract
Background: The medial meniscus posterior root tear is a common cause of knee osteoarthritis, often misdiagnosed. Surgical repair aims to restore knee biomechanics, with evolving techniques focusing on direct fixation. The objective of this study was to evaluate the clinical and radiographic outcomes of arthroscopic soft suture anchor repair, without utilizing the posterior portal technique, for medial meniscus posterior root tears over a 2-year follow-up period. Methods: -test was used to compare the International Knee Documentation Committee Subjective Knee Form (IKDC) and Lysholm score, as well as meniscus extrusion between preoperative and postoperative states. The Wilcoxon signed-rank test was utilized to compare the Kellgren-Lawrence (KL) grades. Healing rates were assessed on magnetic resonance imaging (MRI). Results: = 0.072). Conclusions: Arthroscopic repair of medial meniscus posterior root tears using a soft suture anchor without a posterior portal yielded a high healing rate in MRI and favorable patient-reported outcomes in short-term follow-up duration.
