Top 5 Things You Need to Know About Knee Replacements


Knee replacement surgery is becoming increasingly common, especially among those who suffer from osteoarthritis, rheumatoid arthritis, or certain types of injuries. If you're considering this procedure, it's essential to arm yourself with accurate information. To that end, here are the top five things you need to know about knee replacements, presented by our team of expert MSK doctors at

1. Not Everyone is a Candidate for Knee Replacement

Contrary to popular belief, knee replacement isn't a one-size-fits-all solution. Several factors, such as age, weight, activity level, and overall health, can determine if you're a suitable candidate. An exhaustive medical evaluation, including imaging tests like X-rays or MRIs, will be required to make this assessment.

2. There are Different Types of Knee Replacements

There's more than one type of knee replacement surgery. The two primary categories are total knee replacement (TKR) and partial knee replacement (PKR). In a TKR, the entire knee joint is replaced, whereas in a PKR, only a portion is replaced. Your MSK doctor will guide you in choosing the procedure that’s best suited to your needs.

3. The Importance of Rehabilitation

Rehabilitation is crucial for a successful knee replacement. A carefully structured physiotherapy programme can help you regain strength and mobility more rapidly. At, we offer a holistic approach to rehabilitation that includes both pre-surgery strengthening exercises and post-surgery recovery plans.

4. Risks and Complications

While knee replacement is generally considered safe, like any surgical procedure, it comes with certain risks. Potential complications include infection, blood clots, and issues related to anaesthesia. It's essential to discuss these risks with your MSK doctor to make an informed decision.

5. Longevity of Knee Implants

With modern advancements in medical technology, knee implants are designed to last longer than ever before. Most knee replacements can last 15 to 20 years or even longer. However, the longevity of the implant can vary based on several factors, such as your activity level and body weight.

Understanding these five key aspects can go a long way in preparing you for a knee replacement surgery. While the procedure can dramatically improve your quality of life, it's crucial to go in with realistic expectations and a full understanding of the process, from preparation to recovery.
