Presentation
Painful and swollen knee after basketball and rope skipping 2 days ago.
Patient Data
A large joint effusion is present. There is corticated fragmentation of the tibial tuberosity and adjacent soft tissue swelling suggestive of repetitive trauma and long-standing unfused fragments from previous Osgood Schlatter disease.
There is mild narrowing of the medial tibio-femoral joint compartment and associated minor marginal osteophyte formation and mild tibial subchondral sclerosis. There is pointing of the tibial spines. The articular surfaces are congruent.
There is no varus deformity at the knee. The alignment is otherwise anatomical. No recent or healing fracture is evident.
Case Discussion
There is evidence of osteoarthritis predominantly involving the medial tibio-femoral compartment and long-standing unfused fragments from previous Osgood Schlatter disease.
