When it comes to having good mobility, healthy knees are essential. Experienced orthopaedic surgeon Dr. Sha Wai Leung has performed thousands of knee replacement surgeries for patients with degenerative joint diseases. In a recent interview, Dr Sha explains that poor habits, physical work, poor posture when lifting heavy items are common problems that cause damage to knee joints. In the early stages, medications can help. But when the problem progresses, surgery is the best way. Dr. Sha has diverse experience in treating degenerative knee joints. He points out that knee replacement surgery only takes around an hour, involvingthe replacement of the damaged joint with a metal, artificial one. It only takes patients half a day to start walking again, and they can even be discharged in 3-4 days. The artificial joints nowadays are very durable and can last for around 10 years. Dr. Sha suggests people with degenerative joints can consider having knee replacement to improve their quality of life.
