Whether symptoms are affecting your ability to exercise, enjoy daily activities or continue participating in sport, early assessment and the right treatment strategy can significantly improve long-term outcomes.
At Pro Sports Medicine in Cardiff, we provide a specialist sports medicine approach to knee osteoarthritis, combining accurate diagnosis, advanced imaging, rehabilitation and the latest regenerative medicine and injection therapies to help patients reduce pain, improve function and remain active for longer.
