Hip osteoarthritis and the active patient: will I run again?

The popularity of running as a recreational sport for health gains has steadily increased. Runners may acquire several types of injuries including hip osteoarthritis (OA). Running is possible with mild forms of OA if proper joint mechanics, neuromuscular control, and technique are present. Recent literature will be discussed that builds upon previously published articles regarding forces encountered at the hip joint during running. This article will outline the biomechanics and necessary muscle forces during running, and theories regarding strengthening and neuromuscular control. Perspectives on treatment, based on known evidence and our clinical reasoning are presented.
