Are Lower Passive Anterior Elevation and External Rotation at 6 Weeks Postoperatively Associated With Healing of Isolated Arthroscopic Supraspinatus Repairs? Am. J. Sports Med. (IF 4.2) Pub Date : 2024-04-15 Philippe Collin, Tiago Martinho, Patrick J. Denard, Solenn Gain, Anthony Pernoud, Hugo Bothorel, Alexandre Lädermann
Background:Despite advancements in surgical technique, failure of tendon healing remains a common problem after arthroscopic rotator cuff repair (ARCR).Purpose/Hypothesis:The purpose of this study was to examine the relationship between range of motion (ROM) recovery and healing after ARCR. It was hypothesized that an early loss of ROM would be associated with tendon healing.Study design:Case-control

Comparison of 3 Different Surgical Techniques for Rotator Cuff Repair in a Rabbit Model: Direct Suture, Inlay Suture, and Polyether Ether Ketone (PEEK) Suture Anchor Am. J. Sports Med. (IF 4.2) Pub Date : 2024-04-15 Cancan Du, Wei Chen, Jingchao Fang, Yarui Zhang, Wenqiang Yan, Wenli Dai, Xiaoqing Hu, Yingfang Ao, Shuang Ren, Zhenlong Liu
Background:Rotator cuff tears have been repaired using the transosseous method for decades. The direct suture (DS) technique has been widely used for rotator cuff tears; however, the retear rate is relatively high. Suture anchors are now used frequently for rotator cuff repair (RCR) in accordance with recent developments in materials. However, polyether ether ketone (PEEK) may still cause complications

Comparison of Return to Sports and Competition After the Arthroscopic Bristow-Latarjet Procedure Versus Arthroscopic Bankart Repair in Adolescents With Recurrent Anterior Shoulder Instability Am. J. Sports Med. (IF 4.2) Pub Date : 2024-04-15 Olivier Rosello, Hugo Barret, Tristan Langlais, Pascal Boileau
Background:The use of isolated soft tissue repair versus bone block stabilization for the treatment of recurrent anterior shoulder instability in adolescents has no scientific evidence.Purpose:To compare the clinical outcomes of adolescent patients who underwent isolated arthroscopic Bankart (iB) repair with those who underwent the arthroscopic Bristow-Latarjet procedure in addition to Bankart (BLB)

Decreased Posterior Tibial Slope and Its Association With Pediatric Posterior Cruciate Ligament Injury Am. J. Sports Med. (IF 4.2) Pub Date : 2024-04-15 Rajiv S. Vasudevan, Garrett E. Rupp, Andrew M. Zogby, Tyler Wilps, Tyler Paras, Andrew T. Pennock
Background:Recent adult studies have demonstrated that decreased posterior tibial slope angle (PTSA) may be a risk factor for posterior cruciate ligament (PCL) injury. However, there is no study investigating this phenomenon in a pediatric population. Understanding risk factors for PCL injuries among a pediatric population is important given the recent rise in athletic competition/specialization and

Factors Causing Unintended Sagittal and Axial Alignment Changes in High Tibial Osteotomy: Comparative 3-Dimensional Analysis of Simulation and Actual Surgery Am. J. Sports Med. (IF 4.2) Pub Date : 2024-04-15 Se-Han Jung, Min Jung, Kwangho Chung, Sungjun Kim, Jisoo Park, Ju-Hyung Lee, So-Heun Lee, Chong-Hyuk Choi, Sung-Hwan Kim
Background:Unintended secondary changes in the posterior tibial slope (PTS) and tibial torsion angle (TTA) may occur after medial open-wedge high tibial osteotomy (MOWHTO). In surgical procedures using patient-specific instruments (PSIs), it is essential to reproduce the PTS and TTA that were planned in simulations.Purpose:To analyze the factors causing unintended sagittal and axial alignment changes

Differences Between Traumatic and Degenerative Medial Meniscus Posterior Root Tears: A Systematic Review Am. J. Sports Med. (IF 4.2) Pub Date : 2024-04-11 Kristine Mundal, Andrew G. Geeslin, Eirik Solheim, Eivind Inderhaug
Background:Intact meniscus roots are a prerequisite for normal meniscal function, including even distribution of compressive forces across the knee joint. An injury to the root disrupts the hoop strength of the meniscus and may lead to its extrusion and the development of osteoarthritis. A medial meniscus posterior root tear (MMPRT) is often thought to have a primary degenerative pathogenesis. However

Return to Sports Rates in Pediatric Patients After Bilateral Versus Unilateral Medial Patellofemoral Ligament Reconstruction Am. J. Sports Med. (IF 4.2) Pub Date : 2024-04-11 Michael P. Klueh, Lauren M. Swany, Jonathan P. Troost, Eileen A. Crawford
Background:Patellofemoral instability commonly occurs during sports activities. The return to sports (RTS) rate for pediatric patients after bilateral medial patellofemoral ligament reconstruction (MPFLR) is unknown.Purpose/Hypothesis:The purpose of this study was to evaluate RTS outcomes for pediatric patients undergoing bilateral MPFLR. It was hypothesized that (1) fewer pediatric patients would
