Introduction: Knee osteoarthritis (OA) is the most prevalent OA worldwide, particularly in USA. Studies show that knee leads to functional limitations, including problems with weight tolerance during walking, climbing stairs, household activities, and lightweight package transport. Since quadriceps muscles play a critical role throughout joint, weakness these diminishes capacity protect results...

BACKGROUND Triathlon is an increasingly popular sport at both the elite and the recreational level. However, there have been few high-quality studies of injuries and illnesses among triathletes. OBJECTIVE To register overuse problems and acute injuries among iron-distance triathletes throughout a training season leading up to a major event. METHODS A 26-week prospective cohort study was con...

Background Involvement of the intramuscular (central) tendon in acute hamstring injuries, as detected on magnetic resonance imaging (MRI), may prolong recovery times. To date, it is unclear whether hamstring injuries exhibiting intramuscular tendon involvement can be identified though routine clinical examinations that assess flexibility and strength. Purpose To test whether MRI-detected intr...

BACKGROUND There is a lack of knowledge on the primary and secondary static stabilizing functions of the posterior oblique ligament (POL), the proximal and distal divisions of the superficial medial collateral ligament (sMCL), and the meniscofemoral and meniscotibial portions of the deep medial collateral ligament (MCL). HYPOTHESIS Identification of the primary and secondary stabilizing funct...

Aim: This study aimed to evaluate the anatomy of anterolateral ligament (ALL), ALL injuries and relationship between other knee ligaments injuries, meniscal tears, bone by retrospectively scanning patients’ magnetic resonance imaging (MRI). 
 Material Methods: Our was designed as a retrospective, non-randomized, single-center clinical study. We included MR images 320 patients who applied o...

BACKGROUND The relationship between biological tissue healing following knee injury or surgery and long-term clinical outcome has come to the forefront of sports medicine practice. This has led many knee surgeons to incorporate biologically mediated healing factors into the management of knee injuries. In particular, the clinical use of mesenchymal stem cells has opened new horizons. EVIDENCE...

Meniscus injuries are a common cause of knee pain, accounting for one sixth of knee surgeries. Tears are the most common form of meniscal injuries, and have poor healing ability primarily because less than 25% of the menisci receive a direct blood supply. While surgical treatments have ranged from total to partial meniscectomy, meniscal repair and even meniscus transplantation, all have a high ...
