Functional scores and prosthetic implant placement are different for navigated medial UKA left in varus alignment.

Purpose: The purpose of this study was to analyze the clinical outcomes and radiologic position of the knee in two groups of patients after medial unicompartmental knee arthroplasty (UKA): one group with residual varus axis (RVA) alignment and other one with neutral mechanical axis (NMA) of the lower limb.

Methods: All patients who underwent UKA between January 2015 and January 2018 were evaluated retrospectively. Inclusion criteria were: medial UKA for isolated medial femoro-tibial osteoarthritis, a varus deformity of < 15°, and a minimal follow-up of 2 years.

Tibial tunnel expansion does not correlate with four-strand graft maturation after ACL reconstruction using adjustable cortical suspensory fixation.

Purpose: Anterior cruciate ligament reconstruction (ACLR) using a short, quadrupled semitendinosus (ST-4) autograft, fixed  with an adjustable suspensory fixation (ASF), has several potential advantages. However, the construct is suspected to generate micromotion, tunnel widening and poor graft maturation. The aim of this study was to evaluate post-operative tibial tunnel expansion, graft maturation and clinical outcomes for this type of ACLR.

Two-year postoperative MRI appearances of anterior cruciate ligament hamstrings autografts are not correlated with functional outcomes, anterior laxity, or patient age.

Aims: MRI has been suggested as an objective method of assessing anterior crucate ligament (ACL) graft "ligamentization" after reconstruction. It has been proposed that the MRI appearances could be used as an indicator of graft maturity and used as part of a return-to-sport assessment. The aim of this study was to evaluate the correlation between MRI graft signal and postoperative functional scores, anterior knee laxity, and patient age at operation.

Combined Anterior Cruciate Ligament Primary Repair With an Autograft Reconstruction.

Anterior cruciate ligament (ACL) reconstruction using an autograft gives good results that could provide improved failure rates. ACL augmentation saving the remnant has demonstrated advantages, such as saving vascular supply and nerve receptors, which could be useful for healing. Conversely, isolated repair techniques are gaining interest but do not give good results because structural augmentation is necessary to reinforce the repair and expect healing.

The Migratory Cortical Button: A Rare Case of Hypersensitivity to Titanium after an Anterior Cruciate Ligament Reconstruction.

Allergy to metal, especially to titanium, is a poorly known subject in orthopedic surgery and is mostly found after arthroplasty. Here, we describe an original case of titanium allergy that developed after an anterior cruciate ligament (ACL) reconstruction of the left knee in a patient with a history of severe atopic dermatitis. Three years after the surgery, he returned to the clinic with the femoral cortical button in his hand; he removed the device from the wound when the skin spontaneously opened at the lateral part of the thigh.
