The human patellar tendon is mechanically homogenous at its mid-substance.

The human patellar tendon contains distinct fascicle bundles across its mediolateral and anteroposterior regions. Studies have suggested region-specific behaviour during in vivo actions, but it is unclear whether such regional differences result from localized variation in composition and mechanical properties within the tendon itself. Furthermore, the viscoelastic properties of any region of the human patellar tendon have not been well described previously.

- The dataset includes motion capture, inertial measurement unit data, and sagittal-plane video from 51 healthy participants walking at three speeds (slow, comfortable, fast) with around 60 trials each.
- It contains detailed data such as ground reaction forces from force plates, 3D trajectories from motion capture markers, and accelerometer readings from lower limbs and pelvis, alongside 2D keypoint trajectories analyzed through the OpenPose algorithm.
- The dataset also includes participant demographics and anatomical measurements, making it useful for musculoskeletal modeling, kinematics, and kinetics analysis, as well as for comparing data across different capture methods.
Purpose: Estimating loading of the knee joint may be helpful in managing degenerative joint diseases. Contemporary methods to estimate loading involve calculating knee joint contact forces using musculoskeletal modeling and simulation from motion capture (MOCAP) data, which must be collected in a specialized environment and analyzed by a trained expert. To make the estimation of knee joint loading more accessible, simple input predictors should be used for predicting knee joint loading using artificial neural networks.

- * The study analyzed data from 115 obese individuals and found that predictions of cartilage degeneration were more accurate for the medial compartment of the knee compared to the lateral compartment.
- * Results indicated that using personalized joint geometry improved the accuracy of OA predictions more significantly than tailoring gait data, emphasizing the importance of individual characteristics in understanding knee OA.
The distal semitendinosus tendon is commonly harvested for anterior cruciate ligament reconstruction, inducing substantial morbidity at the knee. The aim of this study was to probe how morphological changes of the semitendinosus muscle after harvest of its distal tendon for anterior cruciate ligament reconstruction affects knee flexion strength and whether the knee flexor synergists can compensate for the knee flexion weakness. Ten participants 8-18 months after anterior cruciate ligament reconstruction with an ipsilateral distal semitendinosus tendon autograft performed isometric knee flexion strength testing (15°, 45°, 60°, and 90°; 0° = knee extension) positioned prone on an isokinetic dynamometer.
