[Objective]To compare the clinical outcomes of posterior cruciate ligament(PCL)reconstruction by all-inside and conven-tional arthroscopic techniques.[Methods]A retrospective study was performed on 74 patients who underwent arthroscopic PCL reconstruc-tion from July 2016 to July 2021.According to doctor-patient discussion,31 patients received all-inside PCL reconstruction with autoge-nous semitendinosus tendon graft(the all-inside group),while the other 43 patients underwent conventional arthroscopic PCL reconstruc-tion with allogeneic tendon graft(the routine group).The perioperative,follow-up and imaging data of the two groups were compared.[Re-sults]The all-inside group proved significantly superior to the routine group in terms of total incision length[(7.1±1.3)cm vs(10.3±2.4)cm,P＜0.001],the walking time[(3.4±2.1)days vs(5.6±3.2)days,P＜0.001],early complication rate(3.2％vs 9.3％,P=0.043)and hospital stay[(7.4±1.8)days vs(10.3±3.6)days,P＜0.001].In addition,the all-inside group resumed full weight-bearing activities significantly earli-er than the routine group[(93.6±11.7)days vs(128.4±12.4)days,P＜0.001].The VAS score,Lysholm score,IKDC grade,knee flexion-ex-tension ROM,posterior drawer test and backward Lachman test significantly improved in both groups over time(P＜0.05).The all-inside group was significantly better than the routine group in terms of knees ROM[(124.4±3.6)° vs(116.5±3.2)°,P＜0.001;(138.7±3.6)° vs(132.6±5.8)°,P＜0.001],Lysholm score[(124.4±3.6)vs(116.5±3.2),P＜0.001;(138.7±3.6)vs(132.6±5.8),P＜0.001]and IKDC grades 3 months postoperatively and at the latest follow-up.Regarding imaging,the all-inside group was also significantly better than the routine group in femoral tunnel variation[case,reduced/no change/enlargement,(23/8/0)vs(13/27/3),P＜0.001].[Conclusion]The all-inside ar-throscopic PCL reconstruction is superior in term of clinical consequence to the conventional arthroscopic PCL reconstruction for this liga-ment rupture.
