BACKGROUND: Medial collateral ligament (MCL) reconstruction of the elbow mandates precise characterization of where the centerline of elbow rotation projects onto the medial epicondyle (ME). A muscle-splitting approach allows the flexor-pronator muscles to remain attached to the ME and facilitates visualization of the MCL remnant, the sublime tubercle, and the ulnohumeral joint line. Knowledge of where the centerline of rotation intersects the ME relative to the ulnohumeral joint line may assist the surgeon during placement of the proximal drill hole...

BACKGROUND: Limited information in basic science and clinical trials exists to determine if ligament healing may be accelerated with the use of biological adjuvants, such as platelet-rich plasma (PRP). However, there has been widespread acceptance of PRP for use in clinical practice, despite an inadequate understanding of its biological mechanism of action. PURPOSE: To determine whether a single dose of PRP could accelerate ligament healing and correspondingly improve histological characteristics and biomechanical properties when injected immediately postoperatively into the injured medial collateral ligament (MCL) of New Zealand White rabbits...

Some patients complain of chronic persistent medial knee pain after isolated low-grade injuries of medial collateral ligaments (MCL). These injuries often respond to various conservative treatments but insufficient healing of ligaments is believed to be responsible for symptoms in this group of patients. We report on successful treatment of chronically symptomatic MCL injuries in 3 patients using autologous leukocyte-reduced platelet-rich plasma (PRP) injections. There were 3 men with a mean age of 39.3 years and a mean disease duration of 10 months...

Introduction: Old neglected posterior type of elbow dislocations is not very common and generally requires open reduction. It was usually treated with open reduction and K-wire stabilization. We did a newer method in which in addition cruciate type ligament reconstruction; we have reconstructed lateral ulnar collateral ligament (LUCL) and UCL (medial collateral ligament) using semitendinosus graft. This allowed extra stability and early mobilization of the elbow joint. Authors report 3-month-old neglected posterior type of elbow dislocation without any fracture...

PURPOSE: Medial soft tissue release in a varus deformity knee during total knee arthroplasty is essential for accurate balancing of the reconstruction. This study attempts to quantify the effect of sequential needle puncturing of the medial collateral ligament (MCL) using a pressure sensor insert (Verasense by OrthoSensor) and gap measurement under tension. METHODS: Cruciate-retaining arthroplasties were placed in 14 cadaveric knees. The MCL was elongated by step-wise perforation, in five sets of five perforations, with the use of an 18-gauge needle, followed by valgus stress...

Background: Jobe revolutionized the treatment of medial ulnar collateral ligament (MUCL) tears with his reconstruction technique. However, not all MUCL injuries require operative management; Rettig showed that 42% of MUCL injuries respond to conservative management. This was improved by Podesta, who showed that augmentation of nonoperative management with platelet-rich plasma (PRP) and magnetic resonance imaging (MRI) for detecting partial MUCL tears resulted in significantly higher success rates...

Md Abu Bakar Siddiq, Israt Jahan
Medial knee pain can originate from both osseous and non-osseous soft tissue structures including medial collateral ligament (MCL), creating a raft for patients' sufferings. Previously published works demonstrated MCL calcification as a rare medial knee pain entity. Alongside physical examination, radio-imaging techniques, namely conventional X-ray, CT/MRI scanning, etc. have been reported to be useful in recognizing MCL calcification. The present study demonstrates MCL calcification in a 60-year-old Asian-Bangladeshi woman, using high frequency diagnostic ultrasonogram and is the first reported study in the literature...

PURPOSE: There has been increased interest in the role of the posterior bundle of the medial collateral ligament (pMUCL) in the elbow, particularly its effects on posteromedial rotatory stability. The ligament's effect in the context of an unfixable coronoid fracture has not been the focus of any study. The purposes of this biomechanical study were to evaluate the stabilizing effect of the pMUCL with a transverse coronoid fracture and to assess the effect of graft reconstruction of the ligament...

Magnetic resonance imaging and a thorough understanding of its interpretation in the diagnosis and management of injuries to the ligaments about the knee is an essential skill for orthopedists. The goal of this review is to provide a description of the native and injured anatomy through magnetic resonance imaging and its correlations, when appropriate, as seen through the arthroscope at the time of surgery. The ligaments of focus include the anterior cruciate ligament, the posterior cruciate ligament, the medial collateral ligament, the posterolateral corner, the anterolateral ligament, and the medial patellofemoral ligament...

Knee laxity, defined as the net translation or rotation of the tibia relative to the femur in a given direction in response to an applied load, is highly variable from person to person. High levels of knee laxity as assessed during routine clinical exams are associated with first-time ligament injury and graft reinjury following reconstruction. During laxity exams, ligaments carry force to resist the applied load; however, relationships between intersubject variations in knee laxity and variations in how ligaments carry force as the knee moves through its passive envelope of motion, which we refer to as ligament engagement, are not well established...

The posteromedial corner of the knee encompasses five medial structures posterior to the medial collateral ligament. With modern MRI systems, these structures are readily identified and can be appreciated in the context of multiligamentous knee injuries. It is recognized that anteromedial rotatory instability results from an injury that involves both the medial collateral ligament and the posterior oblique ligament. Like posterolateral corner injuries, untreated or concurrent posteromedial corner injuries resulting in rotatory instability place additional strain on anterior and posterior cruciate ligament reconstructions, which can ultimately contribute to graft failure and poor clinical outcomes...

BACKGROUND: A hamstring autograft is commonly used in anterior cruciate ligament (ACL) reconstruction (ACLR); however, there is evidence to suggest that the tendons harvested may contribute to medial knee instability. HYPOTHESIS: We tested the hypothesis that the gracilis (G) and semitendinosus (ST) tendons significantly contribute to sagittal, coronal, and/or rotational knee stability in the setting of ACLR with a concurrent partial medial collateral ligament (MCL) injury...
