High-resolution microCT analysis of sclerotic subchondral bone beneath bone-on-bone wear grooves in severe osteoarthritis.
Bone
January 2025
Department of Research and Development, Schulthess Klinik, Lengghalde 2, 8008 Zürich, Switzerland. Electronic address:
Osteoarthritis (OA) is associated with sclerosis, a thickening of the subchondral bone plate, yet little is known about bone adaptations around full-thickness cartilage defects in severe knee OA, particularly beneath bone-on-bone wear grooves. This high-resolution micro-computed tomography (microCT) study aimed to quantify subchondral bone microstructure relative to cartilage defect location, distance from the joint space, and groove depth. Ten tibial plateaus with full-thickness cartilage defects were microCT-scanned to determine defect location and size.

Methods: Three-dimensional (3D) computed tomography (CT) and magnetic resonance imaging (MRI) were obtained in 14 normal knees in full extension. Two types of virtual triple bundle ACL grafts (VACLG) were created.
Measured Resection as Gap Balance Method in Mobile-Bearing Medial Unicompartmental Knee Arthroplasty: A Randomized Controlled Trial.

Department of Joint and Trauma Surgery, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China.
Objective: Gap balancing is a vital process during mobile-bearing unicompartmental knee arthroplasty (MB-UKA). However, this process commonly depends on the surgeon's experience and lacks specific unified standards. This study aimed to propose and evaluate a novel "measured resection" method for gap balance in MB-UKA.

Twin Cities Orthopedics, Edina, Minnesota, USA.
Background: Anterior cruciate ligament (ACL) stress techniques-including single-leg stress radiographs, Telos, and KT-1000 arthrometer-are highly accessible and can provide additional diagnostic information to assess ACL and ACL graft integrity. The degree of anterior tibial translation (ATT) may be useful in guiding treatment when a diagnosis on magnetic resonance imaging is not conclusive or for judging if additional treatments, such as anterolateral complex augmentation, may be necessary.
Purpose/hypothesis: The purpose of this study was to evaluate the effect of increasing posterior tibial slope (PTS) on baseline tibial position (BTP) and side-to-side differences (SSD) in ATT.
Effect of ELHLD peptide for stifle function recovery after tibial plateau leveling osteotomy in dogs.

Department of Veterinary Surgery, College of Veterinary Medicine, Konkuk University, Seoul 05029, Korea.
Importance: Patients with arthritis and ruptured cruciate ligaments typically require surgery. Following surgery, it is necessary to improve joint function in early stage.
Objective: This study aimed to investigate the impact of intraoperative intra-articular injection of the ELHLD peptide (L-glutamyl-L-leucyl-L-histidyl-L-leucyl-L-aspartic acid) on postoperative stifle function in patients with medial patella luxation grade 3 and osteoarthritis grade 2 undergoing tibial plateau leveling osteotomy due to anterior cruciate ligament (ACL) rupture.
