Inside-Out Meniscal Repair: Medial and Lateral Approach.

ABSTRACT: Preservation of meniscal tissue has been proven to be the best approach in most cases of meniscal tears. Currently available techniques for treating a peripheral meniscal tear include inside-out, outside-in, and all-inside techniques. Each of these techniques present potential advantages and disadvantages. Despite technologic advances in all-inside devices, because of implant-related complications, cost concerns, and device availability, the inside-out technique is still the preferred method among many surgeons. Although the inside-out repair technique is considered more technically demanding and requires additional incisions, it has several advantages such as the possibility for an increased number of sutures, creating a stronger construct, and greater versatility in their placement. This article describes the inside-out meniscal repair technique with its corresponding posterolateral and posteromedial surgical approaches.

Project description:BackgroundIn irreducible bucket-handle medial meniscal tears (BHMMTs), the displaced central fragment is rotated 180° or more, meaning reduction is impossible without derotation of the tear. In chronic cases, the rotated meniscus is deformed and degenerated; thus, the issue of reproducibility and repairability arises. This study presents the clinical outcomes of chronic irreducible and unstable locked BHMMTs. Radiological outcomes were also evaluated using magnetic resonance imaging (MRI).MethodsThis is a retrospective study of 37 patients with 11 cases of irreducible BHMMT and 26 cases of reducible but unstable chronic BHMMT who underwent operations between 2011 and 2016. Posterior arthroscopy was performed after temporary meniscus fixation using a provisional needle fixation technique. After the posterior repair with vertical mattress sutures was completed using an all-inside technique, the classic outside-in technique was performed for the anterior third of the meniscus. The Lysholm, International Knee Documentation Committee (IKDC), and Tegner activity scores were obtained from all patients before surgery and at the latest follow-up. Radiological evaluations were performed using MRI before surgery and at 6 months postoperatively.ResultsBetween 2011 and 2016, a total of 37 consecutive patients with irreducible and chronic BHMMTs underwent surgery. The average postoperative follow-up was 7.2 ± 1.4 years (mean ± SD). Postoperative Lysholm (89.57 ± 2.7) and IKDC (87.22 ± 3.2) scores improved significantly at the last follow-up when compared with the pre-operative scores (38.44 ± 4.5 and 23.52 ± 7.8, respectively). According to the Tegner activity scale, patients' postoperative activity levels remained unchanged compared to preoperative levels at the last follow-up.ConclusionPosterior knee arthroscopy with the all-inside posterior suture and inside-out anteromedial suture technique presented in this study yielded excellent clinical outcomes when used to repair chronic irreducible or unstable BHMMTs.Level of evidenceLevel IV.
