[A young man with a painless swelling of the ankle].

A 15-year-old boy presented with a swelling on the dorsolateral side of his right ankle. The swelling was moveable and painless. Radiography showed an exostosis with irregular calcification behind the talus.

Long-term results after a triple arthrodesis of the hindfoot: function and satisfaction in 36 patients.

The long-term functional results of a triple arthrodesis of the hindfoot are not well known. In this retrospective cohort study we therefore investigated pain, function and alignment of the tibiotalar joint, patient satisfaction with the procedure and the prevalence of osteoarthritis (OA) of the tibiotalar joint after a median follow-up of six years. We also aimed to investigate whether there are patient and surgical characteristics associated with the outcome.

Activation of receptor for advanced glycation end products in osteoarthritis leads to increased stimulation of chondrocytes and synoviocytes.

Objective: The major risk factor for osteoarthritis (OA) is aging, but the mechanisms underlying this risk are only partly understood. Age-related accumulation of advanced glycation end products (AGEs) could be one of these mechanisms. We undertook this study to investigate the role of the receptor for AGEs (RAGE) in mediating the cellular effects of AGEs on chondrocytes and fibroblast-like synoviocytes (FLS).
