Magnetic resonance imaging (MRI) is commonly used to assess traumatic and non-traumatic conditions of the knee. Due to its complex and variable anatomy, the posterolateral corner (PLC)—often referred to as the joint’s dark side—remains diagnostically challenging. We aimed to render the diagnostic evaluation of the PLC more functional by combining MRI, varus loading, and image post-processing in a model of graded PLC injury that used sequential transections of the lateral collateral ligament, popliteus tendon, popliteofibular ligament, and anterior cruciate ligament. Ten human cadaveric knee joint specimens underwent imaging in each condition as above, and both unloaded and loaded using an MR-compatible device that standardized loading (of 147 N) and position (at 30° flexion). Following manual segmentation, 3D joint models were used to computationally measure lateral joint space opening for each specimen, configuration, and condition, while manual measurements provided the reference standard. With more extensive ligament deficiency and loading, lateral joint spaces increased significantly. In conclusion, varus stress MRI allows comprehensive PLC evaluation concerning structural integrity and associated functional capacity. Beyond providing normative values of lateral compartment opening, this study has potential implications for diagnostic and surgical decision-making and treatment monitoring in PLC injuries.

“…Computational measurements were based on manual segmentations as before 36 . Briefly, for each specimen, configuration, and condition, the femoral and tibial bone outlines were manually segmented on coronal T1-weighted images using the semiautomatic segmentation function of ITK-SNAP (v3.8, Cognitica, Philadelphia, PA, US) 39 .…”

Background: Fixed flexion deformity (FFD) is a common manifestation of knee osteoarthritis (OA) that significantly impacts patients' functional abilities and quality of life. Surgical correction of FFD during total knee arthroplasty (TKA) aims to restore joint alignment and improve range of motion. However, a comprehensive understanding of the outcomes and factors influencing the success of this procedure is essential. Objectives: This review article aims to provide a comprehensive overview of the results of surgical correction of FFD during TKA in patients with knee OA. It examines the surgical techniques used, evaluates functional outcomes, pain relief, and range of motion improvements, and assesses the reported rates of complications. Additionally, the durability of the correction and its impact on patient satisfaction and quality of life are explored. Factors influencing long-term success or failure of the procedure are identified. Conclusions: Surgical correction of FFD during TKA has shown promising results in terms of functional improvements, pain relief, and range of motion. Patients experience enhanced functional abilities and improved quality of life following surgery. While complications can occur, meticulous surgical techniques, proper patient selection, and adherence to best practices can help minimize their occurrence. Factors such as surgical technique, patient compliance with rehabilitation, implant selection, and patient-specific characteristics influence the long-term success of the procedure.

To learn about the health care of athletes in the knee joint, real-time to monitor the health of the human knee joint according to the cloud. The system uses a depth camera to collect the data information of the human lower limb alignment and obtains the spatial coordinate position of the human lower limb alignment through deep learning; then analyzes and processes the video sequence of the human lower limb alignment, including the wavelet function decomposition of the lower limb alignment information and reconstruction, and finally, the monitoring results were obtained by the knee joint scoring method. The system has completed the design of software and hardware and realized the method of extracting the coordinate information of the main joint points of the human body based on neural network. The health monitoring algorithm finally obtained the knee joint health status of the subjects through the evaluation system. By comparing the real health status of the subjects, the reliability of this research work was verified. The experiment shows that the monitoring error of the system is less than 10%, and the overall error is only 6%. The KSS standard score of the subjects is consistent with the monitoring and evaluation of the system, and the score trend is basically the same. For the situation that the overall score of the system is lower than the KSS standard, after communication and analysis with orthopaedic experts. It is speculated that it may be due to the subjective estimation of the subjects when measuring KSS, and the system monitoring algorithm is relatively strict and more objective. It is proved that the system designed in this paper can effectively monitor the health of athletes’ knee joint.
