Terrible triad of the elbow associates posterior dislocation, radial head fracture and coronoid process fracture. It is a complex trauma, associating severe bone ligament lesions, with high more-or-less long-term risk residual instability, stiffness, pain osteoarthritis. During last 20 years, pathologic, biomechanical clinical knowledge has greatly progressed. Prevention these complications req...

Anterior cruciate ligament (ACL)-derived cells have a character different from medial collateral ligament (MCL)-derived cells. However, the critical difference between ACL and MCL is still unclear in their healing potential and cellular response. The objective of this study was to investigate the mesenchymal differentiation property of each ligament-derived cell. Both ligament-derived cells dif...

Intraoperative injury to the medial collateral ligament (MCL) during total knee arthroplasty (TKA) is a rare but severe complication. The main treatment methods are primary repair and revision with a more constrained implant; however, the clinical outcomes of primary reconstruction without a constrained implant have rarely been reported.A retrospective study was performed to evaluate the preval...

The medial collateral ligament (MCL) is commonly injured in the setting of anterior cruciate ligament (ACL) injuries. Because the MCL has better healing capacity than the ACL, the general perception is that MCL injuries can be treated conservatively. Treating these injuries conservatively, however, can lead to residual valgus laxity. Furthermore, it delays time to surgery, which prevents acute ...

BACKGROUND Medial collateral ligament (MCL) injuries are the second most common injury resulting in player lost time in elite-level ice hockey. PURPOSE To determine the incidence and injury characteristics of knee MCL sprain in male collegiate ice hockey players. STUDY DESIGN Case control. METHODS Athlete exposure data demographics, mechanism of injury, player position, time of injury occ...

BACKGROUND Players in the National Football League (NFL) sustain injuries every season as the result of their participation. One factor associated with the rate of injury is the type of playing surface on which the players participate. HYPOTHESIS There is no difference in the rate of knee sprains and ankle sprains during NFL games when comparing rates of those injuries during games played on ...

Valgus moments on the knee joint during single-leg landing have been suggested as a risk factor for anterior cruciate ligament (ACL) injury. The purpose of this study was to test the influence of isolated valgus moment on ACL strain during single-leg landing. Physiologic levels of valgus moments from an in vivo study of single-leg landing were applied to a three-dimensional dynamic knee model, ...

The role played by macrophage migration inhibitory factor (MIF) in the process of wound healing is controversial. Besides, there have been no reports that investigated the expression or the role of MIF in the repair process after ligament injury. In this study, we hypothesized that the deficiency in MIF gene might delay ligament healing in mice. The aim of this study was to clarify this hypothe...

Forty-five patients with fractures of the tibial spine were reviewed 3 to 10 years after injury in order to determine the degree of residual laxity of the cruciate or collateral ligaments. After fractures which had been partially or completely displaced, some anterior cruciate laxity was evident, even if patients were asymptomatic. It was also found that an anatomical reduction did not prevent ...
