Document Summary
Knee pain in activities such as running, jumping, squatting, and especially going up/down stairs and during kneeling. Also called apophysitis of the tibial tubercle. Due to repetitive quadriceps contraction, fatigue of patellar ligament and tibia under. Inflammation of the patellar ligament as it inserts onto the tibial tuberosity stress and pulls the bone out. Xray, us and mri, soft tissue swelling and bony fragments. Xray : soft tissue swelling (edema, bone fragmentation @ tibial tuberosity, lateral view will show irregular changes in the tibial tuberosity. Can detect swelling within the tissue as well as cartilage swelling @ early stage. Two part patella with an unfused accesory ossification centre superolaterally. More common in males than in females. Only 2% experience symptoms anterior knee pain. If you were to take volume, it would be wider than the mass of the two bones which enables you to distinguish between bipartite and a fracture. Superolateral accessory ossification centre is characteristic of bipartite.
