ABSTRACT
Objective To compare the effect and safety of arthroscopic debridement enmbined with intercondylar fossa angioplasty in the elder with knee osteoarthritis.Methods Six-eight elderly with knee osteoarthritis were selected from June 2012 to December 2014 in this hospital and they were averagely and randomly divided into group A and B.Patients in group A were given arthroscopic debridement,while in group B were given and arthroscopic debridement,intercondylar fossa angioplasty.The levels of VAS scores,Lysholm scores,WOMAC scores and joint range of motion were measured and compared between the two groups after 3 months,6 months and 12 months of operation.The adverse events of the two groups were supervised and compared as well.Results All elder in the two groups had apparently decreasing in VAS scores and WOMAC scores (P＜0.05) after operation.Compared with group A,patients in group B had lower levels of VAS scores and WOMAC scores(P＜0.05) at 12 months after operation.The level of Lysholm score was significantly increased in the two groups after treatment(P＜0.05),while group B had a higher level at 12 months after treatment than group A (P＜0.05).The joint range of motion in the two groups were improved after treatment(P＜0.05).The elder patients in group B had better joint range of motion than group A at 6 and 12 months after operation (P＜0.05).Early postoperative swelling in the joints was the adverse event after operation,but there was no statistically difference between two groups.Conclusion The combination of arthroscopic debridement and intercondylar fossa angioplasty is effective to release knee pain,increase the clinical efficacy and improve the knee function.
