Robotic total knee arthroplasty (TKA) has demonstrated improved component positioning and a reduction of alignment outliers with regard to pre-operative planning.Early robotic TKA technologies were mainly active systems associated with significant technical and surgical complications.Current robotic TKA systems are predominantly semi-active with additional haptic feedback which minimizes iatrogenic soft tissue injury compared to conventional arthroplasty and older systems.Semi-active systems demonstrate advantages in terms of early functional recovery and hospital discharge compared to conventional arthroplasty.Limitations with current robotic technology include high upfront costs, learning curves and lack of long-term outcomes.The short-term gains and greater technical reliability associated with current systems may justify the ongoing investment in robotic technology.Further long-term data are required to fully ascertain the cost-effectiveness of newer robotic systems.

Medical negligence compensation claims in knee meniscal surgery in Norway: a cross-sectional study.
Patient Saf Surg
January 2025
NTNU - Norwegian University of Science and Technology, Trondheim, Norway.
Background: Meniscal surgery is one of the most frequent orthopaedic procedures performed worldwide. There is a wide range of possible treatment errors that can occur following meniscal surgery. In Norway, patients subject to treatment errors by hospitals and private institutions can file a compensation claim free of charge to the Norwegian System of Patient Injury Compensation (NPE).

J Orthop Surg Res
January 2025
Department of Orthopaedics, FuyangHospital of Anhui Medical University, Fuyang, Anhui, China.
Objective: This study aims to elucidate the impact of varying tourniquet application timings on postoperative pain and the bone cement interface following TKA.
Method: Patients who underwent TKA in our department between March 2021 and July 2023 were included in this study. They were randomly assigned to three groups: Group 1 used tourniquets throughout the operation, Group 2 applied tourniquets before the osteotomy, and Group 3 applied tourniquets after completing the osteotomy.
Correlation between medial meniscus degenerative tears and medial meniscus extrusion and dynamics using ultrasonography.
J Orthop Sci
January 2025
Department of Orthopedic Surgery, Graduate School of Medical Science Kanazawa University, 13-1 Takara-machi, Kanazawa-city, 920-8641, Japan.
Background: Evaluating the correlation between degenerative meniscus tears and medial meniscus extrusion is necessary to determine the appropriate treatment plan for early-stage knee osteoarthritis. This study evaluated the relationship between degenerative meniscal tears and medial meniscus extrusion in early-stage knee osteoarthritis by using ultrasonography.
Methods: A total of 132 knees from 123 patients with early-stage knee osteoarthritis were evaluated retrospectively.
Advanced Varus Deformity Associated with Medial Knee Osteoarthritis is a Potential Predictor of Anterior Cruciate Ligament Tear and Risk for Suitable Unicompartmental Knee Arthroplasty.
J Arthroplasty
January 2025
Department of Orthopedic Surgery, Nishinomiya Watanabe Hospital, Hyogo, Japan.
Background: Previous clinical studies suggest that preserving the anterior cruciate ligament (ACL) is crucial for stable knee motion and long-term longevity of the reconstructed knee. The ACL damage or loss often occurs in advanced medial osteoarthritis (OA). This study aimed to investigate the correlation between ACL damage and varus deformity progression as a risk factor for ACL tears in knee OA.

December 2024
The CORE Institute, Phoenix, AZ, USA.
Background: Arthroplasty registries play a critical role in improving the quality of care and performing post-market surveillance of medical devices. We report the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) findings specific to the Biomet Vanguard XP bicruciate-retaining total knee implant.
Methods: Data were collected from MARCQI's 2019 report (February 15, 2012, through December 31, 2018).
