Abstract:

BACKGROUND: Few studies on one-stage arthroscopic combined with arthroscopic reconstruction anterior crueiate ligament (ACL) and posterior cruciate ligament (PCL), especially on mid- and long-term follow-up.
OBJECTIVE: To introduce one-stage arthroscopic reconstruction of ACL and PCL, and to evaluate the mid- and long-term clinical curative effect.
METHODS: From June 2002 to June 2007, 45 patients with ACL and PCL injuries received one-stage arthroscopic reconstruction. Totally 20 cases chosing autografts and 25 cases chosing allografts. The reconstruction with absorbable screw was performed using the single-bundle ACL and PCL technique. Wound was treated simultaneously.
RESULTS AND CONCLUSION: Totally 33 patients were followed up for 3 to 8 years. The range of motor was normal. Anterior drawer test of 3 cases were mild-positive, posterior drawer test of 5 cases were mild-positive. LACHMAN test of 6 cases was mild-positive, pivot shift test of 3 cases was mild-positive. Lysholm score and Larson score of autografts and allografts teams after 3 years construction were higher than those of before reconstruction (P < 0.05). There were no difference in Lysholm score and Larson score between the autografts team and the allografts team (P > 0.05). Eight cases were bone tunnel expansion, including 5 cases of ACL tibial segment, 3 cases of PCL tibial segment. Five cases suffered from hydrops articuli, and then treated with paracentesis and clysis, none were broken again. It is indicated that one-stage arthroscopic reconstruction of ACL and PCL with autograft and allograft can both obtain satisfactory motion range, joint stability and well clinical effect of mid-and long-term follow-up.
