The treatment effect of opening,debridement and double-row fixation using suture anchor for severe patellar tendinopathy / 中华外科杂志

ABSTRACT

Objective@#To evaluate clinical treatment efficacy of double-row fixation with bridging suture anchors for chronic, severe patellar tendinopathy.@*Methods@#A retrospective study of 18 patients suffered from severe patellar tendinopathy and underwent surgical treatment during January 2009 and June 2014 at Department of Orthopedic, Beijing Chao Yang Hospital, Capital Medical University was conducted. All patients had received conservative therapy for more than 6 months(range 6-30 months) but the effect was unsatisfactory. There were 10 males (12 knees) and 8 females (12 knees)with age of 47.2 years(range 32-63 years). Seven cases on the left and 17 cases on the right. The surgical treatment included a midline incision at patellar tendon, complete debridement, and double-row fixation with bridging suture anchors. Visual analogue scale(VAS), Lysholm score were collected preoperatively and postoperatively, and compared by paired-t test. The postoperative complications was recorded.@*Results@#All patients were followed up for 35.7 months (range24-64 months) without any dropout.VAS decreased from 7.5±1.6 preoperative to 1.4±1.0 (t=4.45, P=0.00) postoperative, Lysholm score increased from 48.3±5.2 to 89.6±5.4 (t=-4.88,P=0.00).The Lysholm score was excellent in 3 cases and good in 15 cases.No patellar tendon rupture or suture fixation failure was recorded during the follow-up period.@*Conclusions@#The effect of double-row fixation with bridging suture anchors is satisfactory with few postoperative complications.It can not only improve clinical symptoms of patients, but also restore knee joint function.
