Efficacy of Sodium Hyaluronate Injection Combined with Rehabilitation on Senile Knee Osteoarthritis

Objective:To evaluate the clinical efficacy of sodium hyaluronate plus rehabilitation in treating senile knee osteoarthritis.Methods:We allocated 120 patients with knee osteoarthritis randomly into treatment group and control group with 60 cases each for intracavitary administration of sodium hyaluronate plus rehabilitation training or only physical therapy.The therapeutic effects were evaluated using visual analogue scale(VAS),Lysholm knee score scale and surface electromyogram.Results:The pain was obviously relieved in both groups(P0.05) and better therapeutic effects were achieved in the treatment group.After treatment,83.3%patients in treatment group acquired good knee joint function.There were statistically significant differences in the improvements of median frequency and mean power frequency on the surface electromyogram of quadriceps femoris between the treatment and control groups(P0,01).Conclusion:` Intracavitary administration of sodium hyaluronate plus rehabilitation training have marked therapeutic effects in treating senile knee osteoarthritis and can relieve quadriceps femoris fatigue in these patients.
