Jumpers knee or patellar tendonitis is an overuse injury that results in pain at the front of the knee, localised at a point towards the bottom of the kneecap. Repetitive strain from too much running or jumping causes inflammation or degeneration of the patella tendon.
Patellar tendonitis can be a tricky condition to treat and requires a substantial period of rest and a thorough treatment and rehabilitation program. In the most severe or persistent cases, surgery may be required.
Constant jumping, landing, and changing direction can cause strains, tears, and damage to the patellar tendon. So kids who regularly play sports that involve a lot of repetitive jumping — like track and field (particularly high-jumping), basketball, volleyball, gymnastics, running, and soccer — can put a lot of strain on their knees.
Jumper's knee can seem like a minor injury that isn't really that serious. Because of this, many athletes keep training and competing and tend to ignore the injury or attempt to treat it themselves. But it's important to know that jumper's knee is a serious condition that can get worse over time and ultimately require surgery. Early medical attention and treatment can help prevent continued damage to the knee.
