A radiographic technique to quantify varus and valgus joint laxity in flexion after total knee arthroplasty (TKA) was evaluated by means of inter-rater assessment in 12 patients. The test was shown to have good reliability. The simple method helps to detect instability in knee flexion that might be overlooked in a conventional clinical examination.

Biomechanical correlates of gait and stair climbing are associated with ex vivo cartilage quality in gonarthrotic patients.

Previous evidence highlights the important role of knee joint malalignment and excessive joint moments for the development to knee osteoarthritis. The present study aimed to systematically investigate the interrelationship between three-dimensional knee kinematics during walking and stair climbing and ex-vivo electromechanical measured cartilage quality in 119 patients with end-stage knee osteoarthritis. Patients scheduled for total knee arthroplasty surgery underwent radiographic assessment and biomechanical analysis in gait and stair climbing assessing in vivo knee joint angles and moments during movement dynamics prior to surgery.

Introduction: Anterior knee pain and other patello-femoral (PF) complications frequently limit the success of total knee arthroplasty as the final treatment of end stage osteoarthritis. However, knowledge about the loading conditions at the PF joint remains limited, as no direct measurements are available. We hypothesised that the external knee flexion moment (EFM) is highly predictive of the PF contact forces during activities with substantial flexion of the loaded knee.

Background: Traditional freehand techniques in high tibial osteotomy (HTO) have been shown to lack precision and accuracy. Patient-specific instrumentation (PSI) and fixation created from cross-sectional imaging have recently been introduced to address this problem.
Purpose/hypothesis: The purpose of the study was to compare traditional freehand techniques versus PSI in a human cadaveric model of HTO.
Instrumented Facet Fusion in the Lumbosacral Spine: Long-Term Clinical and Radiographic Results.

Objective: Surgical treatments for degenerative lumbar spinal disorders involve decompression of neural structures and arthrodesis to address pain from unstable intervertebral segments. Lumbar instrumented facet fusion (IFF), a less invasive technique, has shown positive short-term outcomes, but reports on its long-term outcomes are scarce. This study aims to report its long-term biomechanical stability and clinical outcomes.

The purpose of this study is to investigate the influence of kinesiophobia following Total Knee Arthroplasty (TKA) on the rehabilitation outcomes of patients during hospitalization, includes examining the trends in resting pain levels at various time points post-surgery, the trends in active flexion of the knee at various time points post-surgery, and the effects of kinesiophobia on the timing of first postoperative ambulation, the duration of postoperative hospital stay, and the results of the two-minute walk test on the day of discharge. Postoperative kinesiophobia in patients was identified using the Tampa Scale for Kinesiophobia (TSK), with 33 patients scoring >37 points and 35 patients scoring ≤37 points. Resting Pain levels were assessed using the Numerical Rating Scale (NRS) at various time points, including upon return to the ward (T1), the first (T2), second (T3), third (T4), fifth(T5) postoperative days, and the day of discharge (T6).
