Intraoperative changes in medial joint gap after posterior femoral condylar resection, posterior osteophyte removal, and femoral component placement during primary total knee arthroplasty
Nearly 20% of patients are dissatisfied with their postoperative outcomes following total knee arthroplasty (TKA) [1 –5]. Daily activities associated with mid-flexion stability are correlated with patient satisfaction following TKA [6]. A loose flexion joint gap increases mid-flexion joint looseness [7–9]. Moreover, a loose medial flexion joint gap results in inferior postoperative outcomes [10,11]. In contras t, a loose lateral flexion joint gap affects the postoperative knee flexion angle [12]. Lateral looseness might be essential for medial pivot motion in the normal knee [13]. (Source: The Knee)

Variables associated with successful outcome after anterior cruciate ligament reconstruction in recreational athletes: A prospective cohort study
The annual incidence of anterior cruciate ligament (ACL) rupture ranges from 0.03% to 1.62% in recreational athletes [15]. A total of 15,304 ACL ruptures were registered in the United Kingdom National Ligament Registry from January 2012 to December 2019 [4], an approximate prevalence of 0.3% of the adult population. ACL rupture ( ± surgical reconstruction) has a significant negative impact upon a person’s overall health, with high rates of symptomatic tibiofemoral osteoarthritis [12] and impaired knee-related quality of life [3] reported more than five years post-injury.

Plantaris tendon is valuable graft for the medial patellofemoral ligament reconstruction: A biomechanical study
Medial patellofemoral ligament (MPFL) reconstruction is a viable surgical treatment option that yields good to excellent clinical results in properly selected patients treated for recurrent patellar instability [1]. Different anatomic and nonanatomic MPFL reconstruction techniques have been biomechanically analyzed, including distinct graft options and fixation methods [2 –6]. However, there is no widely accepted ideal graft source or surgical technique for MPFL reconstruction that guarantees optimal clinical outcome [7]. (Source: The Knee)

Visualising knee loading patterns during kneeling and the development of a laboratory-based adaptation of the Aberdeen Weight-Bearing Test (Knee)
The ability to kneel is integral to various occupational, leisure, cultural, and religious activities [12]. Trauma, degenerative conditions such as osteoarthritis, or the after-effects of surgery such as tibial nailing, may all lead to difficulty or the inability to kneel [39]. Kneeling as an outcome for total knee arthroplasty (TKA) [1,2,14,13,12,16,21,27,30,34,40,41,33] and tibial nailing is well-documented [4,20,38,35,10,22], and provides a useful indication of knee function to clinicians. A detailed understanding of knee-ground contact would provide insight into injury mechanisms [28], and ideally would couple informat...
