Novel application of an imageless robotic system in simultaneous unicompartmental knee arthroplasty and anterior cruciate ligament reconstruction by Joshua Yeuk Shun Tran, Rex Wang-Fung Mak, Kevin Ki-Wai Ho, Jonathan Patrick Ng, Cham Kit Wong, Gloria Yan-Ting Lam, Tsz Lung Choi, Michael Tim-Yun Ong, Patrick Shu-Hang Yung

“…The robotic system facilitates real-time gap assessment and balancing, reducing the risk of over- or under-constraint during ACL graft tensioning.The procedure was performed with a standard medial parapatellar approach. Key steps included hamstring autograft harvesting, femoral and tibial tunnel creation, and robotic-assisted implant positioning. …”

Lateral Extra-Articular Tenodesis as an Adjunct to ACL Reconstruction by Madeline M. McGovern MD, Sercan Yalcin MD, Natalie A. Lowenstein MPH, Jillian L. Mazzocca BA, Elizabeth G. Matzkin MD, Giovanna Medina MD, PhD

“…Results: In the STABILITY randomized controlled trial, 2-year outcomes demonstrated a clinically and statistically significant decrease in clinical failure from 40% to 25% and graft rupture rate from 11% to 4% with the addition of LET to ACLR with hamstring autograft. Similar return-to-sport rate was seen between cohorts. …”

Neural structural alterations correlates of quadriceps muscle strength deficits in patients after anterior cruciate ligament reconstruction by Le Yu, Shanshan Zheng, Yushi Chen, Xiao'ao Xue, Zikun Wang, JiaYan Cheng, Yang Sun, He Wang, Yinghui Hua

“…In subgroup analyses of ACLR patients with hamstring autografts, we found that higher injured quadriceps muscle strength was associated with higher axial diffusivity (AD, r = 0.616, p = 0.033) of CST structure and lower LSI of quadriceps muscle strength was associated with higher ratio of mean diffusivity (MD, r = −0.682, p = 0.014) and RD (r = −0.759, p = 0.004) in corticospinal tracts of the injured hemisphere to those of the non-injured hemisphere in ACLR patients after controlling for age, BMI, Tegner activity score. …”

Strength of the Uninvolved Limb Following Return to Activity After ACL Injury: Implications for Symmetry as a Marker of Sufficient Strength by Matthew T Hartshorne, Jeffrey A Turner, Kenneth L Cameron, Darin A Padua

“… # Results Significant main effects for limb were observed with the uninvolved limb in the ACL-I group displaying greater strength compared to the dominant limb in the control group for the quadriceps, hamstrings, and gluteus medius, but effect sizes were small (Cohen’s d <0.25). …”
