In the last few years the number of women who practise sport activities has substantially increased and this has led to an increase in the incidence of ACL tear in females. The aim of this study is to assess outcome differences at a minimum 3-year follow-up after ACL reconstruction in women using either a patellar tendon (BPTB) or a quadrupled-looped hamstring (DSTG) autograft fixed with modern devices.

Fifty women with a chronic, isolated ACL tear were randomised to receive a DSTG or BPTB graft for ACL reconstruction. Both groups were comparable as to age, injury-surgery, activity level, meniscal tears, surgical technique and reabilitation. All patients were prospectively evaluated by an independent observer using the IKDC form, the FKSAKP Score, the KT-1000 arthrometer and the Cybex NORM dynamometer. A radiographic study was performed to investigate tunnel widening.

All but two patients were satisfied with the reconstruction. The average side-to-side difference in anterior tibial translation was 2.4 mm in the BPTB group and 2.5 mm in the DSTG group. The final result was A (normal knee) in 56% and in 60% of the BPTB and the DSTG knees, respectively. A failure (4%) was present in each group. Muscle strength deficits at 60°/s, 120°/s and 180°/s were within 10% for extensors and within 5% for flex-ors in both groups. No statistically significant differences were found in terms of subjective satisfaction, objective evaluation, knee stability and muscle strength recovery. The BPTB group showed a higher incidence of postoperative kneeling discomfort (p< 0.05) and a larger area of decreased skin sensitivity (p< 0.001). The DSTG group showed a higher incidence of femoral tunnel widening (p=0.02).

Using strong and stiff fixation devices, ACL reconstruction in women is not influenced by the graft choice.
