             perform. Then this can progress to having pain during and after the activity. This can then progress to a constant pain during activity and prolonged long after the activity. If the tendonitis is left untreated for a long period of time then the tendon could rupture (Arnheim & Prentice, 2000, p. 554). With the mechanism and signs and symptoms stated, the next focus will be on how Jumper's knee is prevalent to volleyball players.
             Jumper's Knee is a very common injury in volleyball players. These players are constantly running and jumping, which is the primary mechanism for this injury. When volleyball players jump and land, there is a forceful contraction of the quadriceps and an intense compression force of the knee. When the volleyball player has begun the season, many times the patellar tendon gets overused. Plus, the playing season is very long, so the tendonitis does not get the chance to heal correctly if the player continues to play. When a volleyball player goes to make a hit or a block, there are fierce accelerating and decelerating forces that the patellar tendon goes through. The constant movements can cause strain, and result in Jumper's Knee. Every movement that a volleyball player has to perform are all mechanisms that could result in patellar tendonitis. .
             There are many anatomical sites include in the knee complex that is apart of the patellar tendon. The bones that are involved are the femur, tibia, and the patella. The tibial tuberosity is a prominence on the tibia that is an important landmark. For the patella, the superior and inferior poles are significant landmarks also. The tendons that are involved are the patellar tendon and quadriceps tendon. The vastus medialis oblique is the primary quadriceps muscle that is involved. However, all of the quadriceps come together to form the quadriceps tendon.
