Association Between Anteromedial Portal versus Tibial Tunnel Drilling and Meniscal Reoperation Risk Following Anterior Cruciate Ligament Reconstruction: A Cohort Study Am. J. Sports Med. (IF 6.202) Pub Date : 2022-06-20 Brent R. Davis, Richard N. Chang, Heather A. Prentice, Samir G. Tejwani, Andrew J. Morris, Gregory B. Maletis
Background: Anterior cruciate ligament reconstruction (ACLR) provides functional stability to an injured knee. While multiple techniques can be used to drill the femoral tunnel during ACLR, a single technique has yet to be proven as clinically superior. One marker of postoperative functional stability is subsequent meniscal tears; a lower risk of subsequent meniscal surgery could be expected with improved

An Increased Allograft Width for Circumferential Labral Reconstruction Better Restores Distractive Stability of the Hip: A Cadaveric Biomechanical Analysis Am. J. Sports Med. (IF 6.202) Pub Date : 2022-06-20 David R. Maldonado, Michael B. Banffy, Dave Huang, Trevor J. Nelson, Shrey Kanjiya, Melodie F. Metzger
Background: Questions remain about whether circumferential labral reconstruction (CLR) using an iliotibial band (ITB) allograft can effectively restore the labral suction seal of the hip. Hypotheses: (1) CLR with an ITB allograft >6.5 mm would restore distractive stability force to that of the intact labrum. (2) CLR with an ITB allograft >6.5 mm would achieve significantly superior distractive stability

The Plug-Type Patch Results in Immediate and Postoperative Advantages in Graft-to-Bone Integration for Bridging Massive Rotator Cuff Tears in a Chronic Rabbit Model Am. J. Sports Med. (IF 6.202) Pub Date : 2022-06-20 Junjie Xu, Kai Huang, Kang Han, Xiulin Wu, Ziyun Li, Ting Zheng, Jia Jiang, Xiaoyu Yan, Wei Su, Jinzhong Zhao
Background: Various patches have been used to bridge massive rotator cuff tears (MRCTs) by reconnecting the cuff tendons to the humeral head, but the outcomes continue to be suboptimal. Notably, the graft-bone junction is a vulnerable site for failure, which requires optimization in patch design and techniques to enhance initial and postoperative fixation strength at the graft-bone interface. Hypothesis:

Biomechanical Comparison of Ulnar Collateral Ligament Reconstruction With and Without Suture Augmentation Am. J. Sports Med. (IF 6.202) Pub Date : 2022-06-20 Michael V. Narvaez, Trevor J. Nelson, Keon Youssefzadeh, Orr Limpisvasti, Melodie F. Metzger
Background: A common concern associated with elbow ulnar collateral ligament (UCL) reconstruction is the amount of time required for recovery and rehabilitation. For example, for Major League Baseball pitchers, the average time to return to competition ranges from 13.8 to 20.5 months. Suture tape augmentation has shown the ability to provide additional soft tissue stability across other joints in the
