Repetitive stress or trauma
High-impact sports like football, gymnastics, and basketball can put excessive strain on the knee.
Reduced blood supply to the bone
A lack of blood flow can weaken the affected bone, causing it to break away.
Genetic factors

Pain during activity
Especially when running, jumping, or bending the knee.
Swelling or stiffness
The knee may feel puffy and difficult to move.
Catching or locking sensation
If loose fragments are present in the joint.
Weakness or instability
The knee may feel like it could give way.
Physical examination
Assessing pain, swelling, and movement limitations.
X-rays or MRI scans
To check for bone separation or loose fragments.
Rest and activity modification
Avoiding high-impact activities to allow healing.
Physiotherapy
Strengthening the knee to improve stability.
Pain relief medication
Anti-inflammatories like ibuprofen can reduce pain and swelling.
Bracing
A knee brace may help stabilise the joint.
Fixation surgery
Screws or pins secure the loose bone fragment.
Debridement (clean-up surgery)
Removing loose fragments if they cannot be fixed.
Cartilage grafting
If severe damage has occurred, a healthy cartilage transplant may be needed.
