Venous thromboembolism prevention protocol for adapting prophylaxis recommendations to the potential risk post total knee replacement: a randomized controlled trial.

Background: Total knee replacement (TKR) is a major orthopedic surgery that is considered high risk for the development of venous thromboembolism (VTE).

Objective: The aim of this study is to evaluate the clinical outcomes that resulted from the use of a new proposed VTE risk stratification protocol for selecting a suitable extended VTE prophylaxis for post TKR surgery patients administered in conjunction with patient education programs.

Method: A randomized controlled trial was conducted in two medical centers in Saudi Arabia.

Patellar tendon autograft reconstruction of the anterior cruciate ligament with and without lateral plasty in advanced-stage chronic laxity. A clinical, prospective, randomized, single-blind study using passive dynamic X-rays.

Purpose: A prospective randomized study was performed to assess the influence of extra-articular ilio-tibial band tenodesis on the results of arthroscopic anterior cruciate ligament (ACL) reconstruction in patients with advanced-stage chronic anterior laxity of the knee.

Methods: Preoperatively, the two constituent groups of our series of 120 patients: group 1 (Kenneth Jones) and group 2 (Kenneth Jones+extra-articular ilio-tibial band tenodesis) were strictly comparable with regard to demographic data, activity level, interval between the injury and the operation, and even objective laxity. Through radiological measurements made by passive dynamic X-rays, we studied the evolution of the objective laxity on the two compartments (medial and lateral) of the knee before the surgery and in review.

Distraction osteogenesis using a longitudinal corticotomy.

Purpose: The purpose of this study was to evaluate whether the use of a longitudinal corticotomy (S-Z osteotomy) results in more rapid consolidation following distraction osteogenesis of short tibiae.

Methods: Sixty-seven lengthening procedures were performed in 51 patients ranging in age from nine to 38 (mean 25) years. Diagnoses included short stature (32 tibiae), postpolio limb deformity (22 tibiae), osteomyelitis (three tibiae), trauma (two tibiae) and other diagnoses (eight tibiae).

The anterolateral ligament of the human knee: an anatomic and histologic study.

Purpose: The functional anatomy of the knee is frequently studied but remains incompletely understood. Numerous authors have described a structure in the lateral knee connecting the lateral femoral condyle with the lateral meniscus and tibial plateau. The goal of this study is to define the incidence, anatomy, and histology of this structure, the anterolateral ligament.
