A knee sprain refers to torn or overstretched ligaments, the tissues that hold bones together. If you have a sprained knee, the structures within the knee joint that connect the thigh bone to the shin bone have been injured.
Hip internal rotation is the twisting movement of your thigh inward from your hip joint. If you try this while standing, your foot should also turn so that your toes are pointing toward the rest of your body.
For hockey great Bobby Orr, a torn knee ligament ended his career at age 30. Orr had more than 17 knee operations, at one point having his meniscus removed—the cartilaginous tissue that helps stabilize and lubricate the knee joint. Now scientists can see in real time just how important the meniscus is.
Patients who have received a new hip joint must first learn to walk "normally" again after the operation. A mobile gait analysis and feedback system developed by a Kaiserslautern research team in cooperation with physicians and biomechanics shall help to achieve this goal.
Patellar tendonitis is a knee injury affecting the patella tendon. It is common in athletes who jump and land with force.
