Abstract:
BACKGROUND:Muscle atrophy and weakness exist around the knee joint of patients with knee osteoarthritis, comprehensive treatment combined with training muscle power around knee joint can obviously relieve symptoms and restore muscle power around the knee joint.
OBJECTIVE:To test the relationship between muscle function around the knee joint and the knee joint function with isokinetic muscle strength test before and after comprehensive treatment of knee osteoarthritis, and to investigate the pathological mechanisms of knee osteoarthritis in order to provide basis for the clinical rehabilitation and treatment.
METHODS:We screened out 30 subjects with unilateral knee osteoarthritis (stage Ⅱ and Ⅲ). Hospital for Special Surgery was used to evaluate the knee function, and visual analogue scale score was used to assess the patient pain. The knee muscle function of knee osteoarthritis patients was measured before treatment;the patients with knee osteoarthritis at stage Ⅱ and Ⅲ received comprehensive treatment for at least 1 month (active quadriceps isometric muscle strengthening exercises, oral celecoxib capsules combined with intra-articular injection of sodium hyaluronate), and knee muscle function was measured after treatment. Hospital for Special Surgery and the visual analogue scale score were evaluated during fol ow-up period.
RESULTS AND CONCLUSION:Compared with the healthy side, the muscle power of the affected side of the patients with knee osteoarthritis was decreased when the flexion and extension muscle peak torque and work volume tested at 60 (°)/s and 180 (°)/s (P<0.05). After comprehensive treatment, the Hospital for Special Surgery scores of the knee osteoarthritis patients were increased significantly (P<0.05), while the visual analogue scale scores were decreased (P<0.05), and the muscle power of the affected side was increased significantly (P<0.05);there was no significant difference in the muscle power
between affected side and healthy side after treatment (P>0.05). There was no significant difference in the peak torque ratio of quadriceps and hamstring measured at 60 (°)/s in the knee osteoarthritis patients before and after treatment (P>0.05), and there was significant difference measured at 180 (°)/s (P<0.05). Knee osteoarthritis patients have decreased muscle strength around the knee joint, and the comprehensive treatment of muscle functional training combined with effective pain relief and nutrition joint drugs can significantly relieve symptoms, improve muscle strength and restore knee function.
