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.

Abstract
The most popular classification of physical disability includes patients following amputation of lower extremities and those with spinal cord impairments. The physical performance of those patients depends on a number of factors, the most important of which include age, sex, type and degree of disability, duration of immobilization or movement restriction, and life style factors, especially those related to physical activity. Physical performance itself is, in turn, a factor contributing to the locomotor ability of disabled patients. Assessment of physical performance relies primarily on determination of the volume and intensity of aerobic and anaerobic metabolism. Both types of metabolism are reduced in subjects with the two types of disability listed above, with more distinct reductions in patients with spinal cord injuries. In this group, physical performance is determined by the level of injury, with increasingly poorer performance in patients with more proximally localised injuries. At the same time, circulatory and respiratory fitness is also impaired and the sympathetic regulatory response is altered. The methods used for the assessment of physical performance are similar to those used in normal subjects, with load programmes and ergometric devices adapted to the type of injury.

Abstract

Background. Thirty two male patients with the full-thickness lesion of articular cartilage on the load-bearing surface of the knee joint (Outerbridge Grade III-IV) were involved in the study. The goal of this paper is the biomechanical assessment of changes in the kinematics of gait of patients after selected articular cartilage surgeries of knee joint examined by the 3D motion analysis system (SIMI Reality Motion Systems GmbH, Germany). Material and methods. Gait of thirty two patients with the articular cartilage surgery of knee joint was analyzed while they underwent 2 out of 4 stages of our original physiotherapy treatment. In order to test the progress of the rehabilitation program the spatial kinematic data of the gait was collected and the angle-time characteristics acquired. The first measurement was taken between the 2nd and 3rd week postoperatively, the second was taken between 6th and 8th week postop. The last measurement was taken between 10th and 14th week postoperatively, when the patient’s gait was fully restored and being improved. The values of step and stride lengths (meters), gait velocity (meters per sec.) and the step cadence (steps per sec.) were monitored as well as the stance and swing ratios (percent of the gait cycle) of the affected and unaffected limb. Range of motion in the knee joint was examined in dynamics and the angles at heel-strike and toe-off measured for both lower limbs. Results. As a consequence of our rehabilitation procedure satisfactory results were obtained individually between 10th and 14th week postop. in test patients with reference to the control group. The spatial gait parameters step and stride lengths have significantly increased and the stance to swing ratio have decreased for the affected limb compared to the first measurement. The gait velocity was found to be doubled. In addition an increase in range of motion in the joints was noticed and the angle characteristics was similar to the one of the control group. Conclusions. The extensive surgical and physiotherapeutic procedures applied in the treatment have improved gait parameters between 10th and 14th week postop in all tested patients.
