Intraoperative avulsion fracture of the intercondylar eminence in Oxford mobile-bearing unicompartmental knee arthroplasty: Case report
Unicompartmental knee arthroplasty (UKA) has good postoperative results and long term survival [1]. Benefits include lower invasiveness, faster recovery and lower mortality compared with total knee arthroplasty (TKA). The revision rate has been reported to be higher than after TKA, however, and complications can occur. Tibial fractures are serious complications that are especially prevalent in Asian individuals [2]. Most of these fractures have been reported to occur in the medial tibial plateau postoperatively, and there is a small number of reports on intraoperative fracture of the intercondylar eminence.

Sagittal mechanical ratio: A novel technique to define sagittal alignment of the femur independent of distal anatomic landmarks
Radiographic measurements to study sagittal alignment in the setting of knee are frequently difficult to evaluate due the presence of a prosthesis or implant that obscures traditional radiographic landmarks. In this paper we present a novel method of determining sagittal femoral alignment in the presence of obscuring implants. (Source: The Knee)

Higher activity level after opening wedge high tibial osteotomy compared to medial unicompartimental knee arthroplasty in a selected cohort of advanced age: A propensity score-matched analysis
High tibial osteotomy (HTO) and medial unicompartmental knee arthroplasty (mUKA) are accepted treatment for medial knee osteoarthritis (OA). Patients often present meeting indications for both procedures. The purpose of this study was to compare results after MOWHTO and UKA in a matched population of patients older than 50 years.

Current concepts in total knee arthroplasty
The general population is aging as life expectancy continues to increase in many parts of the world. Consequently, there has been an exponential rise in the prevalence of chronic degenerative diseases found in the elderly, including osteoarthritis. In turn, the burden of joint replacement surgery has significantly risen. The Covid-19 pandemic has left many countries now facing a massive backlog of patients awaiting their surgery for debilitating arthritis symptoms. Research into total knee replacement (TKR) is therefore important. (Source: The Knee)

Computer-based analysis of different component positions and insert thicknesses on tibio-femoral and patello-femoral joint dynamics after cruciate-retaining total knee replacement
This study aimed to investigate the impact of implant component positioning (anterior-posterior and medio-lateral shift) and varying tibial insert thickness on the tibio-femoral (TF) and patello-femoral (PF) joint kinematics and contact forces after cruciate-retaining (CR)-TKR. (Source: The Knee)

High initial graft tension is a post-operative risk factor for high UTE T2* value of the graft 6 months after anterior cruciate ligament reconstruction
Anterior cruciate ligament (ACL) injury is a common sport injury. ACL reconstruction is performed to regain anterior and rotational stability, which allows a return to sports activities. However, various factors, including younger age, hyperextension of the knee, concomitant meniscal tear, chronic tears, and over-tensioning in graft fixation have been reported as risk factors for re-injury and residual instability [1 –7]. These factors must be overcome to achieve a safer return to sports activity after ACL reconstruction. (Source: The Knee)

Correlation of knee laxity with alignment and repetitive physical activity in patients with knee osteoarthritis: A cross-sectional study
Malalignment, knee laxity, and repetitive physical activity are considered biomechanical risk factors for knee osteoarthritis (KOA), though the correlation among these factors is poorly understood. The purpose of this study was to elucidate the relationship between knee laxity and alignment, and to determine the effects of repetitive physical activity on knee laxity in patients with KOA.

Targeted exercises can improve biomechanical markers in individuals with knee osteoarthritis: A secondary analysis from a cluster randomized controlled trial
Knee osteoarthritis (OA) is a chronic multifactorial disease associated with pain, functional disability, and altered knee biomechanics. Knee OA can still not be cured, but conservative treatments are recommended to reduce symptoms and pain to allow patients to maximize their health and function. Exercise therapy is widely recognized as an effective non-pharmacological treatment modality and is a recommended component in most clinical practice guidelines for patients with knee OA [1 –3]. While studies have consistently shown that exercise in this population reduces pain, improves function, and enhances quality of life, i...
