Driving a wedge between orthotics and illiotibial band strain

in Hip injuries, Knee injuries

Illiotibial band syndrome (ITBS) is a common disorder amongst recreational and competitive runners. In fact, it ranks only behind patellofemoral pain syndrome in frequency(1). The iliotibial band (ITB), a tough band of connective tissue that runs from the hip to the lateral knee, serves as the attachment for the gluteus maximus and the tensor fascia... MORE

in Email Newsletters, Knee injuries

Anterior cruciate ligament (ACL) tears continue to plague athletes in greater numbers each year(1). Unlike some athletic injuries, ACL tears, once healed or repaired, continue to impact future physical activity and joint health. A majority of athletes (around 60%) never return to a competitive level of sport(1). While there may be several reasons for this,... MORE

Cyclops lesions after ACL reconstruction: something to keep an...

in Diagnose & Treat, Knee injuries

Cyclops lesions are a common cause of range of motion limitations after ACL reconstruction. Chris Mallac defines the malady, explores the causes, and suggests ways to prevent this syndrome from occurring.  First described in 1990 by Jackson and Schaefer(1), a cyclops lesion is a reasonably common complication following anterior cruciate ligament reconstruction (ACLR), with the...

Growing Pains: Osgood-Schlatter Disease

in Diagnose & Treat, Email Newsletters, Knee injuries

Adolescence is often a period of rapid growth for most children. Because bones grow faster than muscles, this growth can lead to tension from the tendons at their insertion on the bone, causing an apophysitis. One of the most difficult-to-treat conditions related to such growth is Osgood-Schlatter Disease (OSD), an apophysitis at the tibial tuberosity.... MORE

Does the hip control the knee?

in Email Newsletters, Knee injuries

Knee injuries are the bane of athletes in nearly all sports (see figure 1)(1). Clinicians and sports scientists continue to explore the best way to prevent such injuries. The knee, a hinge joint, moves in the sagittal plane. The thought is that most knee injuries occur from forced movement in the frontal plane. Therefore, control... MORE

How reliable is the gait lab in your pocket?

in Knee injuries, Tools and technology

Patellofemoral pain (PFP) plagues up to 17% of runners who complain of knee pain(1). Often weak gluteus medius muscles are to blame with resulting hip adduction (HADD) and positive Trendelenburg sign during the unilateral stance phase of running. Patellofemoral pain also affects knee flexion (KFLEX) in single stance, with runners avoiding KFLEX to prevent pain.... MORE

Jumping to conclusions about anterior knee pain

in Diagnose & Treat, Knee injuries

Jumper’s knee occurs in 14% of athletes, mostly volleyball, basketball, and handball players(1). The term ‘jumper’s knee’ typically refers to anterior knee pain, usually presumed as patellar tendinopathy. However, a careful history and exam reveal that quadriceps tendinopathy exists in up to 25% of patients. These athletes complain of anterior knee pain at the superiorpole... MORE
