Clininal Outcome of Combined Inside-Out and Outside-in Technique in Miniscus Repair

Abstract

Introduction: The meniscus, a fibrocartilaginous tissue, is essential to the proper operation of the knee joint. Treatment for meniscal injuries depends on a number of factors, including the patient's age, the kind of tear, and the location of the injury. Meniscal tears should be treated as often as practical owing to their critical function in knee biomechanics. Meniscus repair techniques include inside-out, outside-in, and all-inside strategies. The inside-out technique has been the gold-standard technique for meniscal repair. It entails making an incision either posteromedially or posterolaterally to gain access to the posterior capsule and allow sutures to be passed through the menisci with long needles in a vertical or horizontal mattress configuration while being viewed under an arthroscopic microscope. This technique, known as outside-in, involves passing sutures across the rip from the outside to the interior of the joint using a spinal needle. Knots are formed on the intraarticular end of the sutures and used to lessen the meniscal tear. The aim of the study is to evaluate the results of meniscus tears repaired using combined inside-out and outside-in techniques. Method and Analysis: Using the outside-in approach for anterior meniscal tears and the inside-out technique for middle meniscal tears, a retrospective evaluation of patients with meniscus tears treated using combined procedures was conducted. Barrett's criteria and MRI were used to evaluate the clinical progress of meniscal repair. With a significance level of P = 0.05, the Wilcoxon Two Sample Test was employed as the statistical analysis tool together with SPSS 22. Results: 24 patients participated in the research, and their average age was 33.1 years old (range, 19-56 years old). A mean of 12.1 months passed between follow-ups. Complete meniscal healing was accomplished in all three patients except one who had ACL re-rupture. Tegner and Lysholm ratings were lower in patients after ACL reconstruct
