Patellar tendon anterior cruciate ligament reconstruction with conical press-fit femoral fixation: 5-year results in athletes population

Abstract.

Bone–patellar tendon autograft is probably the most widely used graft for ACL reconstruction. Several methods for graft fixation have been described. To avoid intra-articular hardware we adopt biological fixation with a femoral conical press-fit fixation. A prospective study was performed on 40 consecutive active athletes who underwent ACL reconstruction with this technique by the same surgeon between November 1994 and September 1995 (mean follow-up 46 months, range 36–62). Results were evaluated by an independent examiner using radiography, computed tomography, subjective and objective evaluation, and isokinetic and functional strength tests. Assessment using the IKDC knee scoring revealed 85% of the patients with a normal or nearly normal knee joint; Tegner's score was 7.5 preoperatively and 6.0 postoperatively, with 60% of the athletes returning to the preinjury sport and level. No patients had instability, with 90% having less than 3 mm side-to-side difference on computerized analysis. The isokinetic test showed mild quadriceps deficit at 3 and 6 months, with no deficit at final follow-up; four patients complained of anterior knee pain and had a positive kneeling test. We found no graft dislocation. All cases showed radiological evidence of graft integration at 3 months time. Long-term results support this technique as× a simple, cost-effective, and reliable alternative for patellar tendon fixation in ACL reconstruction.
