Results of forty two computer-assisted double level osteotomies for severe genu varum deformity.

Purpose: The goal of this article was to present the clinical and radiological results of 42 severe genu varum operated on between August 2001 and June 2010 using computer navigation.

Methods: All the osteotomies were navigated using the Orthopilot® device (B-Braun-Aesculap, Tuttlingen, Germany). The procedure was performed such that after inserting the rigid bodies and calibrating the lower leg, we first made the femoral closing wedge osteotomy (from four to seven mm) which was fixed by an AO T-Plate, and then, after checking the residual varus, the tibial opening wedge osteotomy was made using a Biosorb® wedge (Tricalcium phosphate, SBM, Lourdes, France) and a plate (AO T-plate or C-plate).

Intraoperative comparisons of knee kinematics of double-bundle versus single-bundle anterior cruciate ligament reconstruction.

Purpose: Based on biomechanical anatomical studies, double-bundle reconstruction of the anterior cruciate ligament (ACL) was introduced to achieve better stability in the knee, particularly in respect of rotatory loads. An in vivo, computer-assisted, double-bundle (DB) ACL reconstruction is superior to a single-bundle (SB) ACL reconstruction at reducing rotatory, and AP laxities of the tibia at 20 degrees of knee flexion and also during the pivot shift test.

Methods: The data of 63 patients who had ACL reconstruction were prospectively collected.

Good surgical outcome of transphyseal ACL reconstruction in skeletally immature patients using four-strand hamstring graft.

Purpose: Our purpose was to evaluate the clinical and radiological outcome at maturity of an « adult-like » transphyseal anterior cruciate ligament (ACL) reconstruction performed in skeletally immature patients using four-strand hamstring graft.

Methods: The records of all skeletally immature patients who underwent transphyseal ACL reconstruction between 2004 and 2006 at our institution were reviewed. Inclusion criteria were age less than 16 years and radiographic evidence of open physes.
