From small jumps to big jumps, jumping is a pretty simple and ordinary action helping us get places and get on or off things. In sports, jumping is just as routine especially where jumping plays a big role in the action such as soccer, basketball, volleyball, tennis and track. It is also the cause of many knee injuries.
Jumper's knee (patella tendonitis) often affects athletes who jump repeatedly with rapid acceleration and deceleration and who play on hard, unforgiving surfaces.
Symptoms: Typically an athlete will feel a shooting pain or aching along the front of the knee that follows sports activity. Swelling might occur, but it is not always an indication of jumper's knee>
Prevention: Strengthening the muscles surrounding the knee cap will help prevent the injury from occurring. Try implementing quad exercises and stretching before your sports season starts and throughout your regular training once the season is underway.
If pain still persists, non-operative treatments include ice, medication, physical therapy and activity restriction and modification. Neoprene braces and straps can also provide support and comfort while playing sports.
If the knee pain persists you may need to consider surgery. The recovery time is often 6 to 12 months accompanied by physical therapy and rehabilitation.
