Osteoarthritis

This 52 year old gentleman complaint of chronic bilateral knee pain worst on the right compared to the left. He gave a history of frequent falls and being active in rugby during his younger days.
This is his right knee x-ray which showed signs of osteoarthritis - reduction in knee joint space, sclerosis of articular margin and osteophyte formation.

This is his left knee x-ray that showed similar signs but to a lesser degree.
A diagnosis of osteoarthritis was made. Interestingly, osteoarthritis usually affects the medial compartment more than the lateral compartment. In this particular case, the lateral compartment is worst affected compared to the medial compartment. This is possibly related to his earlier active younger sporty days and frequent falls.
