Evaluation of Survival and Clinical Outcomes of Patients Treated With Isolated All-inside Meniscal Sutures or With Meniscal Sutures Associated With Ligament Reconstruction

Meniscal tears are among the most common injuries of the knee joint. The average annual incidence is between 60 and 70 cases per 100,000 people. Among young athletes, these injuries account for 20-30% of all knee injuries, while in individuals over 50 they are frequently present even without symptoms (up to 60%). Meniscal tears often coexist with other intra-articular injuries: about one third of all cases occur together with an ACL rupture, which significantly increases the likelihood of a meniscal lesion. Possible treatments range from total meniscectomy, partial or selective meniscectomy, to meniscal suturing. Compared with meniscectomy, meniscal repair preserves meniscal function and reduces the risk of progression to knee osteoarthritis from 51.42% (after meniscectomy) to 21.28% in patients who undergo meniscal repair. The main meniscal suture techniques are classified as inside-out, outside-in, and all-inside. The present study aims to analyze the failure rates in patients who underwent meniscal repair using the all-inside technique at a single referral center, evaluating the complication rate, the need for reoperation, and the clinical satisfaction of the operated patients. The results obtained aim to improve the understanding of the effectiveness of all-inside meniscal sutures-electively used at our referral center-compared with inside-out techniques. The purpose of this study is to collect and analyze the cases of patients surgically treated with all-inside sutures for isolated meniscal tears or tears associated with other ligament injuries. The goal is to evaluate the survival and reoperation rates in patients who underwent all-inside meniscal repair for isolated meniscal injuries or those associated with ligament injuries, aged between 12 and 65 years, operated on at the II Clinic of the Rizzoli Orthopaedic Institute between 01/01/2017 and 30/06/2025, with a minimum follow-up of 2 years.
