ACL reconstruction using femoral Rigid-fix and tibial Bio-intrafix devices.

OBJECTIVES: The objective of this study is to report the clinical and functional outcomes of Hamstring graft ACL reconstruction fixed with femoral Rigid-fix and tibial Bio-intrafix devices.

METHODS: In a prospective study, the clinical (Lysholm score) and functional outcomes (International Knee Documentation Committee, IKDC) of 44 patients who underwent autologus hamstring graft ACL reconstruction using femoral Rigid-fix and tibial Bio-intrafix devices, were evaluated at the end of one year. Joint laxity was assessed with KT-1000 arthrometer (MEDmetric, San Diego, CA).

RESULTS: None of the patients complained of instability, joint swelling or severe pain in the postoperative period. The IKDC score improved from 66.62 + 5.36 to 92.36 + 5.30 (P < 0.001). Lysholm scores in the preoperative and follow up period were 68.28 + 5.54 and 93.87 + 4.75 respectively; the improvement was statistically significant with P value < 0.001. Similarly, the mean anterior translation of tibia improved from 7.45 mm in the preoperative period to 3.89 mm after one year of ACL reconstruction. Associated meniscus injury didn't have significant impact on the overall outcome. No intraoperative or postoperative complications were documented.

CONCLUSION: Hamstring graft fixation using femoral Rigid-fix and tibial Bio-intrafix devices provide secure graft fixation and allows aggressive rehabilitation. The clinical and functional outcome of this hybrid fixation technique is rewarding.
