Patellar tendonitis (also known as patellar tendinosis or colloquially as jumper’s knee) is an overuse injury caused by repetitive overloading of the extensor mechanism of the knee. This repetitive overloading causes microtearing of the patellar tendon near the point of attachment to the patellar which then progresses to inflammation of the tendon. Most affected individuals are between 10 and 16 years old and the incidence tends to be highest in sports involving jumping, like basketball or volleyball. Risk factors include weal gluteal muscles and muscle tightness in the calves, quadriceps and hamstrings. The braces below are designed to reduce the pain of the condition by applying pressure to the site of the inflammation. Please check with us or with your doctor to ensure your choice is right for you.
