The pain in the knee joints had gradually increased over the last 10 years. At the time of presentation the patient was severely incapacitated and could not walk without support. There was no history of trauma.

On clinical examination, there was diffuse swelling around both the knee joints. A distinct swelling was also present in the region of upper one third of the tibia on both sides.

Painless mobility waspresent at the level of the tibial swellings. Radiographs of both lower limbs were taken and are shown in fig 1.
