Do You Need to Have a Knee Replacement Surgery? Here are some Fast Facts

Knee Pain

Knee PainArthroplasty, commonly known as knee replacement surgery, is performed to replace a diseased, worn, or damaged knee with artificial knee components. It is actually a pretty common procedure for knee pain that is typically due to arthritis. In Wales and England, over 70,000 knee replacement procedures are performed every year, and this number keeps rising. The majority of people who undergo knee replacement surgery are those older than 65 years old.

Knee Replacement Surgery: The Basics

Your knee joint is composed of your femur, your thigh bone’s bottommost portion, and your tibia, your shinbone’s uppermost portion. These are covered and protected by a smooth cartilage to make sure they can glide over each other smoothly. When your cartilage gets injured or worn due to arthritis, your knee joint will become stiff and painful, drastically reducing your mobility.

Depending on your knee joint’s specific condition, you may be required to have some or your entire knee joint replaced. If you suffer from arthritis in just one portion of your keen joint — typically the medial compartment — a unicondylar knee replacement, also called Partial Knee Replacement (PRK), may be an option for you. A Total Knee Replacement (TKR), however, is more commonly recommended.

An artificial knee joint can significantly reduce your pain and bring back some of your mobility, but it won’t be capable of performing the same range of movement as a natural knee joint. Artificial knee components are usually composed of metal and plastic and can last you 20 years.

When to Have Knee Replacement Surgery

Although the most common reason people choose to undergo knee replacement surgery is osteoarthritis, these conditions that can likewise damage your knee joint and warrant a knee replacement:

  • Severe knee injuries
  • Rheumatoid arthritis
  • Gout
  • Haemophilia

Your doctor may recommend the procedure if you experience severe knee joint stiffness, swelling and pain resulting in reduced mobility and if your knee joint pain is so intense that it significantly interferes your sleep and your daily activities. A knee replacement procedure is a major operation, so it is usually only recommended if simpler treatments including steroid injections and physiotherapy have not succeeded in improving your mobility and reducing pain.
