Abstract
Background. Meniscus injuries are one of the most common injuries to the knee joint. Diagnosis of meniscus damage in combination with osteoarthritis of the knee joint is difficult due to the large number of false positive and false negative results. A biomechanical study of gait will allow you to study the results of treatment and rehabilitation of patients after arthroscopic resection.
Materials and Methods. Examined 47 patients with traumatic and degenerative tears of the menisci of the knee joint. Before and after surgical treatment of 10 people (group 1), only before treatment 22 (group 2), only after surgical treatment, 15 patients (group 3). We studied the biomechanics of walking and the function of the knee and hip joints. In group 1 the time from the onset of the disease until surgical treatment was 9.7 months. Rating of KOOS scale before treatment was 29.4 score, after treatment of 80.2 In the
Results. The timing of walking cycle found no differences from the norm in all groups. For the first group after the operation discovered a reliable increase in the amplitude of extension of the hip joint, for both the operated and intact legs. In groups 2 and 3, this regularity is not statistically significant. Movement abduction-adduction, and rotation in the hip joint have not found significant changes in all three groups. In the first group before the treatment, the kinematics of the knee joint at saggital plane on the side of the lesion does not differ from intact. After treatment decreased of the phase of the maximum amplitude on the operated side. Itself amplitude of flexion increases, but the change does not reach the statistically siginficance because of the high scatter of the data. The second and third groups have a same significant difference in the phase of flexion on the intact side. Range of motion at frontal plane on the intact side after the surgery in the first group decreased statistically significant.
Conclusion Thus, damage to the meniscus lead to less degree of motion disorders during level gait, which successfully compensated.
