Patient specific instrumentation allow precise derotational correction of femoral and tibial torsional deformities.

Background: Rotational malalignment deformities of the lower limb in adults mostly arise from excessive femoral anteversion and/or excessive external tibial torsion. The aim of this study was to assess the correction accuracy of a patient specific cutting guides (PSCG) used in tibial and femoral correction for lower-limb torsional deformities.

Methods: Forty knees (32 patients) were included prospectively.

Resection of calcaneonavicular coalition: Arthroscopic or open approach?

Purpose: Calcaneonavicular coalition accounts for more than half of all tarsal coalitions. Resection of calcaneonavicular coalition by an open approach is the standard treatment. Treatment of calcaneonavicular coalition by an arthroscopic approach appears promising.

Posteromedial Opening-Wedge Tibial Osteotomy for Metaphyseal Varus and Abnormal Posterior Slope Correction in Failed Anterior Cruciate Ligament Reconstructions Using a Custom Cutting Guide.

Anterior cruciate ligament reconstruction after graft failure may need associated bone correction to ensure stability of the knee. This article presents a technique of posteromedial opening-wedge osteotomy using a custom cutting guide to correct increased tibial slope and metaphyseal varus deformity after recurrent graft failure. An autograft quadriceps tendon graft was selected for the revision anterior cruciate ligament graft.

Femoral and tibial bone bruise volume is not correlated with ALL injury or rotational instability in patients with ACL-deficient knee.

Purpose: Some researchers have suggested that bone bruises are evidence of rotational instability. The hypothesis was that the extent of lateral bone edema is correlated with the presence of an anterolateral ligament (ALL) injury. The main objective was to determine whether there was a correlation between the presence of an ALL injury the extent of bone bruises.

Outpatient total knee arthroplasty: Readmission and complication rates on day 30 in 61 patients.

Background: Total knee arthroplasty (TKA) on an outpatient basis is controversial due to concerns about patient safety. In France, only 1.1% of TKAs performed in 2017 were outpatient procedures.
