THURSDAY, Jan. 22, 2015 (HealthDay News) -- Having knee pain while using the stairs may be an early sign of arthritis, a new study suggests.
"At present, we have little concept of 'early' osteoarthritis and often only see people when they have significant, longstanding pain and loss of function," research leader Philip Conaghan, a professor of musculoskeletal medicine at the University of Leeds in England, said in a university news release.
"This research is vital to understanding early symptoms of knee osteoarthritis," he said.
