Study on application of ultrasound-guided intraarticular PRP precision injection assisted all-inside reconstruction for posterior cruciate ligament injury
Objective To study the clinical effect of ultrasound-guided intraarticular platelet rich plasma(PRP)precision injection assisted all-inside reconstruction for posterior cruciate ligament(PCL)injury.Methods 44 patients with PCL injuries who were hospitalized for surgical treatment were divided into a control group and an experimental group according to the random number table method,with 22 cases in each group.The experimental group underwent ultrasound-guided intraarticular PRP precision injection assisted all-inside reconstruction,while the control group underwent all-inside reconstruction surgery.Both groups underwent functional exercise after surgery.The surgery and follow-up conditions of the two groups were analyzed,and the magnetic resonance imaging(MRI)scores of the grafts at 6 months postoperatively and the difference of the posterior laxity of both knees preoperatively and postoperatively,the International Knee Documentation Committee Knee Evaluation(IKDC)scores,and the American Orthopedic Foot and Ankle Society(AOFAS)ankle hindfoot score were compared between the two groups.Results All patients in the two groups successfully completed the operation,and the surgical incisions healed well.After normal discharge,rehabilitation training was carried out according to the doctor's advice,and regular review was conducted.All patients were followed up for more than 1 year,and no complications related to the autodonor tendon area were found during the follow-up.Preoperatively and at 3,6,and 12 months postoperatively,the IKDC scores of the affected knee joints of the patients in the experimental group were(51.6±3.7),(78.3±4.1),(87.5±2.6),and(92.2±2.1)points,and those of the control group were(50.5±4.7),(74.8±4.2),(82.9±4.0),and(90.2±3.1)points.At 3,6,and 12 months postoperatively,the IKDC scores of the affected knee joints of patients in both groups were significantly improved compared with those preoperatively;while the improvement at 6 and 12 months postoperatively were more significant compared with that at 3 months postoperatively,and the improvement at 12 months postoperatively were more significant compared with that at 6 months postoperatively;the difference was statistically significant(P＜0.05).The IKDC scores of the affected knee joints of the experimental group were significantly better than those of the control group at 3,6,and 12 months postoperatively,and the difference was statistically significant(P＜0.05).Preoperatively and at 3,6,and 12 months postoperatively,the AOFAS ankle hindfoot scores of the patients in the experimental group were(98.7±1.0),(98.4±0.8),(98.5±0.9),(98.6±0.8)points,and those in the control group were(98.2±0.9),(98.0±0.8),(98.3±0.9),(98.4±1.0),and(98.4±1.0)points.The AOFAS ankle-hindfoot scores of the patients in both groups at 3,6,and 12 months postoperatively were not statistically significant from that preoperatively(P＞0.05).There was also no statistically significant difference in AOFAS ankle-hindfoot scores preoperatively and at 3,6,and 12 months postoperatively between the groups(P＞0.05).At 6 months postoperatively,a follow-up MRI of the knee joint showed that the reconstructed ligaments in both groups of patients were in good condition,and the tendon bone healing was satisfactory.The MRI scores of the grafts in the experimental group were significantly better than those in the control group at 6 months postoperatively,and the difference was statistically significant(P＜0.05).Preoperatively,the difference of the posterior laxity of both knees were(13.6±1.4)mm in the experimental group and(13.9±1.5)mm in the control group;at 12 months postoperatively,the difference of the posterior laxity of both knees ranged from 2 to 7 mm in the experimental group,with an average of(4.0±1.4)mm;the difference of the posterior laxity of both knees ranged from 2 to 6 mm in the control group,with an average of(3.5±1.2)mm.At 12 months postoperatively,the difference of the posterior laxity of both knees in both groups was significantly improved compared with that preoperatively,the difference was statistically significant(P＜0.05),but there was no statistical difference in difference of the posterior laxity of both knees between the two groups preoperatively and at 12 months postoperatively(P＞0.05).Conclusion Ultrasound-guided intraarticular PRP precision injection assisted all-inside reconstruction can accelerate the functional recovery of knee joint in patients with PCL injury,effectively promote graft remodeling and tendine-bone healing,and the clinical efficacy is satisfactory.
