Abstract:
Objective To compare the curative effect of 360° arthroscopic denervation and routine arthroscopic debridement in treatment of knee osteoarthritis.Methods A total of 85 patients were included in the study after excluding the 5 follow-up dropout among the 90 patients with knee osteoarthritis treated between May 2006 and May 2011.Subsequently,the odd and even quality of the mantissa of admission number was used to determine the groups:Group A,42 patients underwent routine arthroscopic debridement; Group B,43 patients underwent arthroscopic debridement plus 360 degree denervation.Traumatic and degenerative arthritis occurred in 30 and 55 patients respectively.There were 34 male and 51 female patients whose mean age was 63 years (range,52-73 years).Western Ontario and McMaster University Osteoarthritis Index (WOMAC),MOS item short from health survey (SF-36),and visual analogue score (VAS) were compared between the two groups before and after operation.Results WOMAC score and SF-36 score of the two groups improved after surgery.At postoperative 6 months,12 months,and 24 months,WOMAC in Group B scored 81.0,78.5,and 82.4 respectively,lower than 86.8,83.8,and 91.7 in Group A (P ＜ 0.05) ; SF-36 in group B scored 47.4,46.3,and 44.4 respectively,higher than 43.9,41.4,and 39.5 in group A (P ＜ 0.05).At postoperative 1 week,VAS of group B was 1.6 points,lower than 2.6 points in group A (P ＜ 0.05).There was no statistical difference between the two groups in postoperative swelling of joint (P ＞ 0.05).Conclusions According to the area involved in knee osteoarthritis and characteristics of innervation of knee joint synovium,arthroscopic 360° denervation provides thorough debridement and removes as many innervation of knee joint synovium.Arthroscopic 360° denervation is superior to the routine arthroscopic debridement in improvement and duration of the symptoms.
