Background: The purpose of this retrospective study was to assess the clinical and radiographic outcomes of large and massive rotator tears treated with arthroscopic complete repair with a posterior interval slide compared with partial repair without a posterior interval slide at a minimum follow-up of 5 years.
Methods: This study included 58 patients with large and massive rotator cuff tears that were unable to be treated with arthroscopic complete repair with an anterior interval slide and margin convergence alone. Each patient underwent either arthroscopic complete repair with an additional posterior interval slide and a subsequent side-to-side repair of the interval slide edge (complete-repair group) or arthroscopic partial repair with margin convergence and without the additional posterior interval slide (partial-repair group).
Background: While the medial meniscal posterior horn (MMPH) is reported to bear a considerable portion of overall load on the knee joint, including compressive and shear forces, no study has yet investigated the relationship between the MMPH and posterior tibial slope (PTS), which is a geometric factor associated with the shear force component in the presence of a compressive load in the knee joint.
Hypothesis/purpose: The purpose was to investigate the relationship between the PTS and MMPH tears in patients without ligamentous injury. It was hypothesized that the PTS is greater in patients with MMPH tears as compared with those without.
