Abstract：Objective:To explore the effect and experience of line suture anchor nail surgery in the treatment of acute traumatic patellar dislocation.Method:20 cases(20 knee,the experimental group) of acute traumatic patellar dislocation(for pure dislocation,not cartilage fracture, meniscus injury,cruciate ligament damage,etc.),patients with the arthroscopic microscopic diagnosis,articular cavity cleaning,lateral patellar retinaculum release,with small incision mediopatellar support and joint capsule line suture anchor nail repair,tightening,to observe the early clinical curative effect,with Lysholm score evaluation was knee joint function before and after operation,and always using traditional suture repair methods in the control group(20 cases,20 knee) in operation time,blood loss,postoperative recovery normal knee joint mobility postoperative recovery time of knees squats,returned to normal after running time,and after 2,4,6,8 weeks Lysholm the mean score were compared.Result:20 cases(20 knee) were for follow-up,follow-up of 4-31 months,an average of 15 months.Before all of the patients had no knee pain,elastic ring,no recurrent dislocation of the knee joint motion were back to normal,the experimental group and the control group in operation time,surgical blood loss,there were no statistical significance(P>0.05),postoperative recovery time normal knee joint mobility,postoperative recovery time of knees squats,returned to normal after running time there was statistical significance(P<0.05).Lysholm mean score was (96.7±2.0),compared with the control group was (85.9±2.0),the difference was statistically significant(P<0.05).Review of X-ray or CT pills,all patients were reset was good,with wire anchors were not loose or broken. Conclusion:Line suture anchor nail surgery in the treatment of acute traumatic patellar dislocation,as small arthroscopic surgery,trauma,and reset fixed firmer,early exercise,strengthening the knee muscle strength and joint mobility reduce complications,can short the recovery period,achieve a good reliable early clinical curative effect,restore the daily work,exercise,learning,long-term effect remains to be further follow-up observation.
