Abstract:
Objective To evaluate the clinical outcomes of arthroscopic reconstruction of anterior cruciate ligament (ACL) with femoral tunnel made by three-portal technique.Methods From February 2014 to May 2015,fifty-five ACL rupture patients (38 males and 17 females) with mean age 31.46±7.34 (range,16 to 48) who underwent single-bundle ACL reconstruction with femoral tunnel made by three-portal technique by the same surgeon were followed up.The average preoperative duration was 15.39±18.57 (range,5 to 180) days.All patients presented the positive Lachman test,of which 32 patients had 1 grade pivot-shift test,15 patients 2 grade and 8 patients 3 grade.At final follow-up,the International Knee Documentation Committee (IKDC) and Lysholm scores were used to estimate knee joint function,while the Lachman test and pivot-shift test were used to estimate knee joint stability.Results All patients were followed up for 26.73±5.23 (range,21 to 34) months.The femoral tunnel positions were accurate without fracture of the back walls in all patients.The mean length of femoral tunnel was 38.58±3.76 (range,35 to 42) mm,and the mean angles of femoral tunnel on coronal plane was 49.32°±2.45° (range,45° to 52°).All patients presented negative Lachman test.Fifty-one patients presented negative pivot-shift test,while the remaining 4 patients had 1 grade of the rotational lax-ity.Forty-nine patients showed normal range of motion,while two had 5° flexion deficit,one had less than 5° flexion deficit and three had 5° hyper-extension loss.Furthermore,the IKDC score significantly was improved from 73.31 ±5.83 preoperatively to 94.63±3.16 at the latest follow-up (t=10.14,P＜0.001).The Lysholm score significantly was increased from 66.35±8.91 preoperatively to 95.32±4.25 at final follow up (t=12.76,P＜0.001).Condusion Arthroscopic reconstruction of ACL with femoral tunnel made by three-portal technique is an reliable technique with the advantage of simple procedure and accurate femoral tunnel position in surgery.
