ABSTRACT

Objective To investigate the clinical effect of arthroscopic debridement combined with patellofemoral peripheral denervated operation in treating patellofemoral arthritis.Methods One hundred cases of patellofemoral arthritis anterior knee pain in this hospital from January 2014 to September 2015 were selected and randomly divided into the observation group and control group,50 cases in each group.The control group was given the arthroscopic debridement treatment,while the observation group was given the arthroscopic debridement combined with patellofemoral peripheral denervated operation.The visual analogue scale (VAS) before and after treatment,and Lysholm and Kujala scores after treatment were compared between the two groups.Results There was no statistically significant difference in the VAS score before treatment between the two groups (P＞0.05).After treatment,the VAS score in the two groups were significantly decreased,moreover the VAS score in the observation group was lower than that of the control group (P＜0.05).After treatment,the Lysholm scores in the observation group and the control group were (80.93±4.21) points and (74.29±4.48) points,the knee Lysholm scores of claudication,joint noose,bearing weight,pain,instability,up and down stairs,jump,run,joint swollen and pain,squats were significantly better than those in the control group (P＜0.05);aftertreatment,the Kujala total score in the observation group and the control group were (76.48±6.54) points and (68.34-±-6.22) points respectively,the Kujala scores of claudication,walking distance,bearing weight,squat,up and down stairs,jumping,running,knee pain,long time kneebend,abnormal patellofemoral activity,anterior knee swelling,knee bending limitation,thigh muscle atrophy in the observation group were significantly better than those in the control group(P＜0.05).Conclusion Arthroscopic debridement combined with patellofemoral peripheral denervation surgery in the treatment of patellofemoral osteoarthritis can obviously relieve pain and improves the knee function and patellofemoral joint function.
