Prospective analysis of radiofrequency versus mechanical debridement in treatment of knee osteoarthritis / 中华创伤骨科杂志

ABSTRACT

Objective To analyse the differences between radiofrequency and mechanical debridement in treatment of knee osteoarthritis. Methods Randomized control and prospective case study were designed, with 24 cases in the radiofrequency treatment group and 36 cases in the mechanical debridement group (the control). All the cases were followed up for an average of 12.4 months (ranging 6 to 24months) according to Lysholm knee function evaluation score. Results The Lysholm scores for the treatment group were superior to those in the control group in cases of Outbridge grades Ⅱ and Ⅱ-Ⅲ chondromalacia (P0.05). Conclusion Radiofrequency is the first choice in treatment of chondromalacic lesions of no more than Outbridge grade Ⅲ.
