Concomitant Opening-Wedge Distal Femoral Osteotomy and Anterior Closing-Wedge Proximal Tibial Osteotomy With Tunnel Bone Grafting for the First Stage of a Revision Anterior Cruciate Ligament Reconstruction

Arthroscopy Techniques
Multiple risk factors for anterior cruciate ligament (ACL) reconstruction graft failure have been reported, including improper tunnel placement, unrepaired meniscus or ligamentous injuries, and coronal/sagittal malalignment. Various biomechanical studies

Comparable outcomes and early revision rates between restricted and unrestricted functional knee positioning in robotic‐assisted total knee arthroplasty for varus deformities ≥10°

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Functional knee positioning (FKPos) in total knee arthroplasty (TKA) optimises outcomes by balancing individual anatomical and soft tissue characteristics. Managing marked varus deformity presents challenges in achieving balance when tibial alignment is restricted to 3° of varus, necessitating either medial soft tissue release or ...

Medial parapatellar surgical approach leads to greater loss of postural sway complexity compared to mid‐vastus approach in women undergoing total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Total knee arthroplasty (TKA) is associated with acute postoperative effects that increase the risk of falls. These effects differ between the medial parapatellar (PP) and mid‐vastus (MV) surgical techniques but have not been evaluated in terms of postural sway complexity.

Steep medial posterior tibial slope angle and ramp lesion are independent risk factors for an increase in quantitatively measured pivot shift in patients with ACL‐deficient knees

Journal of Experimental Orthopaedics
Background Delayed anterior cruciate ligament (ACL) reconstruction often causes residual anterolateral rotatory instability (ALRI) and consequent knee osteoarthritis, warranting the recommendation of early ACL reconstruction within 6 months after injury.

Lateral posterior tibial slope correlates with tibial and femoral tunnel widening after anatomical reconstruction of anterior cruciate ligament using autologous quadrupled-hamstring tendons, A CT study

Medicine Science
In the present study, we aimed to determine the risk factors predicting femoral and/or tibial tunnel widening after single-bundle anatomical anterior cruciate ligament reconstruction using hamstring autograft and to investigate the effect of tunnel ...

Smaller hamstrings autograft size after primary ACL reconstruction is associated with higher odds for graft failure: A meta‐analysis on autografts sizes covering 46,268 patients

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the association between autograft size and graft failure for hamstrings tendon (HT), patellar tendon (PT) and quadriceps tendon (QT) autografts. Methods Medline, PubMed, Cochrane Library, Embase, Amed and Web of Science were searched at four separate time points, with the most recent search in February 2025.

Proximal anatomical axes show bidirectional variability: Accurate tibial slope requires mechanical axis measurement

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To determine whether posterior tibial slope (PTS) measured to proximal anatomical axes can serve as a reliable proxy for PTS measured to the mechanical tibial axis (mTA). Methods In patients ≥18 years with failed anterior cruciate ligament reconstruction, medial and lateral PTS were measured relative to the mTA on a lateral lower‐leg ...

Tendency of Tibial Component Placement and Short-Term Outcomes in ROSA-Assisted Unicompartmental Knee Arthroplasty Using the Persona Partial Knee System

Arthroplasty Today
Background: Robot-assisted unicompartmental knee arthroplasty (UKA) has been introduced to improve component positioning. The ROSA Knee System and Persona Partial Knee (Zimmer Biomet, Warsaw, IN, USA) constitute a relatively new robotic platform with ...

Personalized alignment in total knee arthroplasty reduces patellar tilt: A retrospective study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral kinematics is crucial for patient satisfaction following total knee arthroplasty (TKA). A postoperative patellar tilt greater than 5° has been associated with inferior clinical outcomes. While a femoral component external rotation beyond 3° is generally protective against patellar tilt, personalized alignment may not ...
