The Comparison Of Clinical Result Between Internally Braced And Standard Anterior Cruciate Ligament Reconstructions

Purpose: The present study aimed to compare instrumented knee joint stability and function after after internally braced and standard anterior cruciate ligament reconstruction(ACLR)for anterior cruciate ligament(ACL)tears.To explore whether internally braced ACLR would work better than standard ACLR at 1-year follow-up.Methods: Review the clinical data of 90 patients,between September 2020 and March 2022,who met the selection criteria with ACL tears.30 patients underwent independent internally braced ACLR,30 patients underwent woven internally braced ACLR,and 30 patients underwent standard ACLR.Following-up examinations were performed at 3,6,and 12 months.The Lysholm,IKDC and HSS score at each follow-up time node after surgery in the three groups were recorded.The difference in anterior tibial translation were measured at 12 months postoperatively.Furthermore,the rates of recurrent instability,other complications,and revision surgery were recorded.Results: The mean age at inclusion was 34.40 ± 8.38 years in the standard ACLR group,31.33 ± 7.76 years in the woven internally braced ACLR group and 31.87 ±7.60 years in independent internally braced ACLR group.At 1 year postoperatively,all patients were follow-up and no adverse results were reported.The mean Lysholm scores of the three groups were 94.67 ± 2.16,94.33 ± 2.92,94.07 ± 2.60(P=0.633),mean IKDC scores of 61.07 ± 3.63,61.60 ± 3.46,62.33 ± 4.43(P=0.656)and 100.00 ±0.00,100.000.00(P=1.000).At 1 years,the difference in anterior tibial translation was3.47±0.47 mm in the standard ACLR group,1.97±0.23 mm years in the woven internally braced ACLR group and 2.21±0.42 mm years in independent internally braced ACLR group(P<0.0001).Conclusion: At 1 years postoperatively,internally braced of the ACLR did not affect the postoperative knee joint function recovery and effectively limited the previously observed decrease in postoperative knee joint stability over time.Whatever the way that the internal brace device assisted ACLR can provide a reliable treatment for patients with small tendon graft diameter or high return to sports needs,especially in avoiding graft laxity.
