Cortical femoral suspensory fixation using screw post in anatomic single-bundle anterior cruciate ligament reconstruction: a prospective study and mid-term outcome results.

PURPOSE

Cortical femoral suspensory fixation using screw post in ACLR has the advantage of allowing complete filling of the femoral tunnel with graft tissue. In addition, the low cost of the implants is an advantage in countries where cost is an issue of concern. The purpose of the current study was to evaluate the clinical functional outcome results of cortical femoral suspensory fixation using screw post at mid-term follow-up.

METHODS

Single surgeon single centre prospective case series study. Sixty two patients having complete ACL tears were included in the current study. Average follow-up was 52.6 months (range 38-68). Objective and subjective IKDC scores, Lysholm knee score, SF-36 score, VAS for patients' satisfaction, VAS for pain and Kellgren & Lawrence (K/L) classification of osteoarthritis were used for follow-up evaluation.

RESULTS

Objective IKDC score revealed that 59 patients had grade "A" and 3 had grade "B", while no single patient had neither grade "C" nor "D". The average Lysholm score was 90.7, average subjective IKDC was 89.5. Average SF-36 score was 94.8. The average VAS for operation satisfaction was 9.4. Average VAS for pain was 0.2. Forty six patients were classified as normal K/L classification, nine were grade "1", seven were grade "2". Comparing pre-operative and follow-up objective IKDC, subjective IKDC, Lysholm, SF-36, and VAS for pain scores revealed statistically significant differences (P-value <0.05).

CONCLUSION

Femoral suspensory fixation using screw post in ACLR showed excellent functional outcome results at mid-term follow-up.
