In order to assess the strength of the bone tissue in patients undergoing joint replacement of the knee or hip joint, resected bone fragments were tested on a test-stand, ИСС/М-Scaime ZF-500, installed at the department of traumatology and orthopedics of the Rostov state medical university. Later, the bone strength indicators were compared to the following: data obtained from densitometry, gender, age and the osteoporosis risk factors of the patient. Based on multivariate analysis, medical treatment and rehabilitation methods were devised for the patients after a joint replacement of the knee or hip joint.
