The medial collateral ligament complex is the primary constraint of the elbow to valgus forces and is composed of the anterior bundle, the posterior bundle, and a transverse part. Total and partial ruptures have been described. Clinical and radiologic examinations of medial or valgus instability of the elbow are difficult. The effect of different stages of medial collateral ligament ruptures on...

We have shown in a previous study that patients with combined lesions of the anterior cruciate (ACL) and medial collateral ligaments (MCL) had similar anteroposterior (AP) but greater valgus laxity at 30° after reconstruction of the ACL when compared with patients who had undergone reconstruction of an isolated ACL injury. The present study investigated the same cohort of patients after a minim...

The success of total knee arthroplasty depends in part on proper soft tissue management to achieve a stable joint. It is unknown to what degree total knee arthroplasty changes joint stability. We used a surgical navigation system to intraoperatively measure joint stability in 24 patients under going primary total knee arthroplasty to address two questions: (1) Is the total arc of varus-valgus m...

Valgus elbow stress leads to medial tension and lateral compression injuries in baseball pitchers of all ages. This study was undertaken to investigate the relationship between elbow stress in professional baseball pitchers and the kinematic parameters of pitching mechanics. This was done in an attempt to understand valgus extension overload better and in an effort to improve preventive and reh...

Background: Hallux valgus the most common forefoot deformity stretches the medial cutaneous nerve. There is a paucity of information regarding neuropathy associated with this often-progressive deformation. Methods: The current study involves two groups: 30 patients examined prior to hallux valgus surgery and 30 foot surgery candidates without hallux valgus that were scheduled for a different op...

Minimally invasive techniques for hallux valgus correction include arthroscopy, percutaneous and minimum incision surgery. In the last few decades, several techniques have been increasingly used. We performed a comprehensive search of CINAHL, Embase, Medline, HealthSTAR and the Cochrane Central Registry of Controlled Trials, from inception of the database to 4 January 2010, using various combin...

Purpose To compare navigation and weight bearing radiographic measurements of mechanical axis (MA) before and after closed wedge high tibial osteotomy (HTO) and to evaluate post-osteotomy changes in MA assessed during application of external varus or valgus force. Materials and Methods Data from 30 consecutive patients (30 knees) who underwent computer-assisted closed-wedge HTO were prospecti...

©2003 British Editorial Society of Bone and Joint Surgery doi:10.1302/0301-620X.85B7.14405 $2.00 e studied the stabilising effect of prosthetic replacement of the radial head and repair of the medial collateral ligament (MCL) after excision of the radial head and section of the MCL in five cadaver elbows. Division of the MCL increased valgus angulation (mean 3.9 ± 1.5 ̊) and internal rotatory la...

Introduction: Dynamic knee valgus and poor technique during landing are not only key risk factors for lower extremity injuries especially knee injury, it also can reduce performance. Sportsmetrics soccer training is one of the successful knee injury prevention and enhancement performance protocols in female soccer players. But, the effect of Sportsmetrics soccer training has not been investigat...
