The knee is one of the most complex and important joints in the body, playing a key role in both daily movement and athletic performance. Because of its structure and constant use, the knee is highly prone to injury — whether from a sudden impact, twisting motion, or long-term wear and tear such as osteoarthritis. While physiotherapy can often relieve pain and restore function, in some cases surgery may be necessary to repair damage or improve stability. Following knee surgery, physiotherapy plays a vital role in regaining strength, mobility, and full functional recovery.
