Abstract

PASSARELLI, Marcus Ceregatti et al. Comparison of Puddu osteotomy with or without autologous bone grafting: a prospective clinical trial. Rev. bras. ortop. [online]. 2017, vol.52, n.5, pp.555-560. ISSN 0102-3616.  http://dx.doi.org/10.1016/j.rboe.2017.09.001.

Objectives:

To test the hypothesis that autologous iliac bone grafts do not enhance clinical results and do not decrease complication rates in patients undergoing medial opening-wedge high tibial , osteotomy.

Methods:

Forty patients allocated in a randomized, two-armed, double-blinded clinical trial were evaluated between 2007 and 2010. One group received bone graft, and the other group was left without filling the osteotomy defect. The primary outcome was the Knee Society Score. , Radiographic measurement of the frontal anatomical femoral-tibial angle and the progression of osteoarthritis according to the modified Ahlback classification were used as secondary outcomes.

,

Results:

There was no difference in KSS scale between the graft group (64.4 ± 21.8) and the graftless group (61.6 ± 17.3; p= 0.309). There was no difference of angle between the femur and tibia in the frontal plane between the groups (graft, = 184 ± 4.6 degrees, graftless = 183.4 ± 5.1 degrees; p= 1.0), indicating that there is no loss of correction due to the lack of the graft. There was significant aggravation of osteoarthritis in a greater number of patients in a graft group (p= 0.005) .

Conclusion:

Autologous iliac bone graft does not improve clinical outcomes in medium and long-term follow-up of medial opening-wedge high tibial osteotomy fixed with a first generation Puddu plate in the conditions of this study.
