Abstract
Background. This paper presents a biomechanical assessment of changes in the kinematics of gait of patients following selected types of articular cartilage surgery of the knee joint, examined with a 3D motion analysis system (SIMI Reality Motion Systems GmbH, Germany). Material and methods. The gait of thirty-two patients after articular cartilage surgery of the knee joint was analyzed in the course of 2 out of 4 stages of our original physiotherapy treatment. Monitoring the progress of the rehabilitation programme involved recording of spatial kinematic data of the gait and angle-time characteristics. The first measurement was taken between the 2nd and 3rd week postoperatively, the second was taken between the 6th and 8th postoperative week. The last measurement was taken between the 10th and 14th week postoperatively, when the patient’s gait was fully restored and being improved. Results. Satisfactory individual results in patients undergoing our rehabilitation programme were obtained in test patients compared to the control group between the 10th and 14th postoperative week. The spatial gait parameters: step and stride lengths were significantly increased and the stance-to-swing ratio decreased for the affected limb compared to the first measurement. Gait velocity was also found to have doubled. In addition the range of motion in the joints was increased and the angle characteristics were similar in the test patients and the control group. Conclusions. The extensive surgical and physiotherapeutic management improved gait parameters between the 10th and 14th postoperative week in all patients.
