A comparative study on clinical effects of anterior cruciate ligament reconstruction with or without remnant preservation
Objective To compare the clinical outcomes of anterior cruciate ligament(ACL)rupture by arthroscopic ACL reconstruction with or without remnant preservation.Methods This prospective study was con-ducted on 80 patients with traumatic ACL rupture admitted to Tangshan Second Hospital from Jan.2020 to Jan.2022,including 46 males and 34 females aged 18-55(mean 37.2)years.All patients underwent arthroscopic ACL reconstruction.During surgery,the ACL remnants of 40 patients were preserved(preservation group)and another 40 patients were completely removed(non-preservation group).The deviation rate of bone tunnel positioning points for tibia and femur,knee joint stability by drawer test and Lachman test,knee joint proprioception,and knee joint Ly-sholm score were compared between the two groups.Results There was no statistically significant difference in the deviation rate of tibial and femoral bone tunnel positioning points between the two groups(P＞0.05).After surgery,the preservation group showed much better knee joint stability at both postoperative 6 months(Lachman test:38-/2+vs.33-/7+;drawer test:38-/2+vs.34-/6+)and 12 months(Lachman test:37-/3+vs.31-/9+;drawer test:37-/3+vs.32-/8+,all P＜0.05).Moreover,the preservation group revealed minor difference between the reconstructed po-sition perception and actual angle of the knee joint at postoperative 6 months(2.85°±0.98° vs.4.18°±1.21°)and 12 months(2.33°±1.34° vs.3.74°±1.57°,both P＜0.05),and much higher Lysholm scores of the knee joint after surgery(3 months:76.1±4.2 vs.72.9±3.8;6 months:84.6±3.6 vs.81.5±4.3;12 months:94.2±3.3 vs.89.5±2.8,all P＜0.05).Conclusion During arthroscopic ACL reconstruction of ACL rupture,remnant preser-vation,in contrast to remnant removal,shows similar accuracy of bone tunnel positioning but is superior in knee joint functional recovery(stability,proprioception,and Lysholm score),and thus the comprehensive therapeutic effect is better.
