Adjuvant Medial Collateral Ligament Release at the Time of Knee Arthroscopy: A Controlled Percutaneous Technique.

The posterior horn of the medial meniscus can be challenging to view during arthroscopy because the medial femoral condyle obstructs vision, especially in tight medial compartments. Previous studies have described techniques for improving access, one being a percutaneous medial collateral ligament (MCL) release. This technique allows for increased medial compartment space, which offloads a tight medial compartment, minimizes iatrogenic chondral injury, incomplete meniscal resection, uncontrolled MCL rupture, and allows for accurate diagnosis and management.

Six Percent Incidence of Graft-Tunnel Mismatch in Anatomic Anterior Cruciate Ligament Reconstruction Using Bone-Patella Tendon-Bone Autograft and Anteromedial Portal Drilling.

Purpose: The purpose of this study was to determine the incidence of graft-tunnel mismatch (GTM) when performing anatomic anterior cruciate ligament reconstruction (ACLR) using bone-patella tendon-bone (BPTB) grafts and anteromedial portal drilling.

Methods: Beginning in November 2018, 100 consecutive patients who underwent ACLR by two sports fellowship-trained, orthopedic surgeons using BPTB autograft and anteromedial portal drilling were prospectively identified. The BPTB graft dimensions and the femoral tunnel distance, tibial tunnel distance, intra-articular distance, and total distance were measured.

Unrestricted stride detection during stair climbing using IMUs.

Stride detection, or the identification of the initial (IC) and terminal contact (TC) of the feet while walking, is important for gait analysis. Automatic stride detection based only on kinematic data is challenging, even when using portable, low-cost, user-friendly Inertial Measurement Units (IMUs). Although there are algorithms for straight walking available, they are often not applicable to other movement patterns.

Multimodal Ultrasound Versus MRI for the Diagnosis and Monitoring of Achilles Tendinopathy: A Prospective Longitudinal Study.

Background: The diagnosis and monitoring of Achilles tendinopathy with imaging are challenging.
