Introduction/Objective. The essence of the treatment of degenerative knee joint diseases is pain relief, restoring motion range and stability of knee joints. Methods. In this study, 35 patients participated after having surgery of the knee joint. The patients had a posterior-stabilized (PS) endoprosthesis in one joint, and a posterior cruciate ligament retaining (CR) endoprosthesis in the other. Kinematic data was collected using a 3D optical system for tracking fluorescent markers in time. Based on these data, the following parameters were determined: degree of flexion, mediolateral (ML) translation, lateral gap, medial gap, and the angle of change between the transtibial and transfemoral axes. Results. The results show a more pronounced flexion degree with the PS prosthesis compared to the CR prosthesis. Also, the results show negligible values of the ML translation, lateral gap, and medial gap in both types of prostheses. Using the non-parameter Wilcoxon test, a substantial diffe...
