Objective: Physiologically, the vastus medialis muscle is the first muscle to undergo muscle atrophy, and it was thought that pain in patients with knee osteoarthritis could be reduced if this muscle could be strengthened and stabilized. The purpose of this study was to prove the effectiveness in knee osteoarthritis using polydioxanone sutures that have been tried in other musculoskeletal areas.
Method: Forty knee osteoarthritis patients voluntarily participated in the study, and divided into 30 polydioxanone suture needle (MEST-B2375 produced by Ovmedi Co.) and 10 sham needle (without suture). And the needles were inserted into the vastus medialis muscle. In all patients, safety evaluation including blood tests and ultrasonography as well as efficacy evaluation including isometric maximal contractile strength of quadriceps muscle, weight bearing pain, impression of change, quadriceps angle, rescue drug intake were evaluated up to 30 weeks after the procedure.
Results: Isometric maximal contractile strength showed a significant improvement at 4 weeks after the procedure in the polydioxanone suture group, and the weight-bearing pain showed a significant improvement at every visit in the polydioxanone suture group compared with baseline values. Patient global impression of change score showed significant improvement at 20 and 30 weeks, and clinical score showed improvement at every visit.
Conclusion: Insertion of polydioxanone sutures showed improvement in muscle strength and knee pain by supporting and fixation of the vastus medialis muscle in patients with degenerative knee osteoarthritis. Insertion of polydioxanone sutures is considered to have a therapeutic effect in knee osteoarthritis patients.
