[Arthroscopic denervation of patella combined with microfracture for patellofemoral arthritis].

OBJECTIVE:To explore the clinical effect of knee denervation combined with micro-fracture under arthroscope in the treatment of patellofemoral arthritis. METHODS:From May 2015 to May 2018, 60 patients with knee joint degenerative patellofemoral arthritis were treated, including 28 males and 32 females, aged from 24 to 56(40.5±3.35) years old. Among them, 30 cases underwent arthroscopic debridement alone(control group), 30 cases underwent arthroscopic debridement, peripatellar denervation combined with cartilage cone and patellofemoral articular surface microfracture treatment (treatment group). VAS, Lysholm and Kujala scores were used to evaluate the therapeutic effect. RESULTS:No complications such as wound infection, vascular nerve injury and deep venous thrombosis occurred in all patients. The patients were followed up for 7 to 36 months with an average of 12.5 months. The VAS scores of the two groups were improved 4 weeks after operation, and the improvement of the treatment group was significantly better than that of the control group, the difference was statistically significant (P<0.05). Lysholm and Kujala scores were compared at the last follow-up of the two groups, the improvement of the treatment group was significantly better than that of the control group. CONCLUSIONS:The treatment of patellofemoral arthritis with patellar denervation combined with microfracture can better relieve pain and improve knee function.
