Comparison of the Radiologic, Arthroscopic, and Clinical Outcomes between Repaired versus Unrepaired Medial Meniscus Posterior Horn Root Tear During Open Wedge High Tibial Osteotomy

This study compared the radiologic, arthroscopic, and clinical outcomes between repaired and unrepaired MMPHRT during OWHTO. Fifty-seven patients were prospectively enrolled from 2014 to 2016. The radiologic, arthroscopic, and clinical outcomes were compared between 25 patients who underwent OWHTO with all-inside repair of MMPRT using FasT-Fix (repaired group) and 32 patients who underwent OWHTO without repair of MMPRT (unrepaired group) with a mean 2-year follow up in both groups. The meniscal healing status was classified as complete, partial, or no healing, according to second-look arthroscopic findings. The medial meniscal extrusion (MME) was evaluated using magnetic resonance imaging. The width of medial joint space, joint line convergence angle (JLCA), posterior tibial slope (PTS), Kellgren–Lawrence (KL) grade, hip-knee-ankle angle, and weight-bearing line ratio was evaluated on simple standing. The clinical outcomes were evaluated using the Knee Society score and the Western Ontario and McMaster University score. Healing rates (partial and complete) of the MMPHRT showed a statistical difference between the two groups (repaired group vs. unrepaired group, 19/25 (76%) vs. 13/32 (40.6%), p = 0.008). The postoperative MME showed no statistical differences between groups (repaired versus unrepaired group: 4.5 ± 1.3 mm vs. 4.5 ± 2.1 mm, p = 0.909). The postoperative width of medial join...

Fatty infiltration of the rotator cuff musculature increases in larger tears  and is a factor in retearing. However, tearing may recur even in patients with small original tears and little fatty infiltration of the rotator cuff musculature. We devised a system to classify the rotator cuff tendon stump by magnetic resonance imaging (MRI) signal intensity and investigated pr ognosis-related factors associated with retear based on other MRI findings.

This study aimed to clarify the advantages of three-dimensional (3D) magnetic resonance imaging (MRI) over two-dimensional (2D) MRI in measuring the size of the medial meniscus (MM) and to analyse the volumes of MM and the extruded meniscus in patients with MM posterior root tear (MMPRT), at 10 ° and 90° knee flexion.MethodsThis study included 17 patients with MMPRTs and 15 volunteers with uninjured knees. The MMs were manually segmented for 3D reconstruction; thereafter, the extruded part separated from the tibial edge was determined. The length, width, height, and extrusion of MM were measured by the 2D and 3D me...

This study aimed to compare sagittal medial tibial slope and medial tibial plateau depth between knees with and without medial meniscus posterior root tears.MethodsNine healthy volunteers, 24 patients who underwent anterior cruciate ligament reconstruction, and 36 patients who underwent medial meniscus posterior root pullout repair were included. Magnetic resonance imaging examinations were performed in the 10 °-knee-flexed position. The medial tibial slope and medial tibial plateau depth were compared among the groups.ResultsIn healthy volunteers, the anterior cruciate ligament reconstruction group, and the medial men...

ConclusionsArthroscopic GACI produces satisfactory clinical and radiologic outcomes, and histologic evaluation confirms sufficient regeneration of hyaline-like cartilage that correlates with improved symptoms. Therefore, it is an acceptable, minimally invasive, and technically simple option for the restoration of cartilage defects of the knee.Level of evidenceIV.

AbstractPurposeTo compare the function and activity level after one-anchor repair versus two-anchor repair of the anterior talofibular ligament (ATFL) in patients with chronic lateral ankle instability.MethodsAll patients who underwent arthroscopic surgical ATFL repair using suture anchors were included in this study. The American Orthopedic Foot and Ankle Society (AOFAS) score, Karlsson Ankle Functional Score (Karlsson score) and Tegner activity score were used to evaluate ankle function at a follow-up of a minimum of 2  years. A magnetic resonance imaging (MRI) scan was performed to evaluate the repaired ATFL.Result...

MillettAbstractSurgical management for glenohumeral instability has advanced to provide stronger fixation and to be less invasive. Arthroscopic suture anchor repair has been the gold standard for isolated capsulolabral tears over the years. Despite the ability of the solid suture anchors to handle physiologic load, they can present challenges such as chondral damage due to anchor size and imperfect angulation, osteolysis, anchor breakage, revision drilling, di...

Jesse, James Genuario, Omer Mei-DanAbstractStrains of the adductor muscle are common among athletes, but avulsion at its insertion is rare. Likewise, the diagnosis and management of distal ruptures of the adductors are infrequently reported in the literature. Presented here are the common presenting clinical findings of chronic distal adductor longus tendon ruptures and a description of how these can be successfully treated with a previously undescribed surgical technique. Preoperative and postoperative magnetic...

ConclusionA supplementary MRI will increase diagnostic accuracy when fewer than three clinical findings are present in a symptomatic meniscal repair patient. The clinical relevance of this finding is that MRI contributes to enhancing the diagnostic accuracy of an unhealed meniscal repair when there are limited clinical signs of meniscal pathology.Level of evidenceIII.

Abstract Autologous chondrocyte implantation (ACI) has been used to treat cartilage defects for>20 years, with promising clinical outcomes. Here, we report two first-in-man cases (patient A and B) treated with combined autologous chondrocyte and bone marrow mesenchymal stromal cell implantation (CACAMI), with 8-year follow up. Two patients with International Cartilage Repair Society (ICRS) grade III-IV cartilage lesions underwent a co-implantation of autologous chondrocytes and bone marrow-derived mesenchymal stromal cells (BM-MSCs) between February 2008 and October 2009. In brief, chondrocytes and BM-MSCs were...
