Abstract:
Objective To observe the effect of the improvement of soft tissue tension around the grade II Knee Osteoarthritis (KOA) by the treatment of the radiofrequency needle scalpel combined with ozone injection. Methods Choose 60 patients with unilateral knee osteoarthritis,whose KL classification is class II. The treatment group received RF needle knife combined with ozone treatment and the control group received manual treatment.Pain VAS score and osteoarthritis WOMAC index were used to evaluate the efficacy before and after treatment.Meanwhile, soft tissue tensiometer was used to measure the displacement(FDD value) of 4 points around the knee at 200×g pressure. Results After treatment, the score of VAS in the treatment group and the control group were decreased. The WOMAC index was improved compared with that before treatment and the difference was statistically significant. The score of VAS and WOMAC index in the treatment group were significantly improved than those in the control group.After treatment, the FDD values of the medial femoris muscle,intermediate femoris muscle, lateral femoris muscle and the midpoint of the patellar ligament(2cm above the patella) in the treatment group and the control group were improved, which the difference was statistically significant. Conclusion Radiofrequency needle knife combined with ozone injection and manipulation can improve the pain and function of knee joint, but the former is better than the latter in terms of pain, function improvement and clinical efficacy. Both treatments can affect the soft tissue tension around the knee joint,reduce the soft tissue tension around the knee joint and improve the mechanical microenvironment.
