Plancher Orthopaedics breaks down the complexities of the procedure and the recovery process, giving you the insights needed for an informed choice about your knee’s future.

Key Takeaways

• Knee arthroplasty, commonly known as knee replacement surgery, is intended to alleviate severe knee pain and improve quality of life, with variations including Total Knee Arthroplasty (TKA) and Partial Knee Arthroplasty (PKA) designed for different patterns and severities of arthritis.
• The procedure typically results in significant pain relief and improved mobility, with an overall positive impact on mental health and quality of life; knee implants are generally durable, lasting 15-20 years with high success rates.
• Potential risks such as blood clots, nerve damage, infection, and the need for revision surgery must be recognized; the decision to undergo knee arthroplasty involves assessing these risks, understanding the expected benefits, and careful pre- and postoperative planning.

Understanding Knee Arthroplasty

Knee arthroplasty, also known as knee replacement surgery, serves as a beacon of hope for those suffering from severe knee arthritis. This modern medical procedure involves replacing damaged knee joint surfaces with artificial components, aiming to alleviate pain and improve the quality of life for patients. The knee, an engineering masterpiece in its own right, is a complex joint consisting of bones, ligaments, and cartilage, all of which can succumb to the relentless wear and tear of life.

The decision to undergo this procedure is a serious one, generally rooted in severe pain, specifically severe knee pain, and a substantial loss of joint function that significantly disrupts a person’s quality of life. No longer exclusive to the elderly, knee arthroplasty now offers solace to younger patients as well, reflecting advancements in surgical techniques that promise reliable outcomes even for those in the prime of their lives suffering from end-stage degenerative knee osteoarthritis.

Total vs. Partial Knee Replacement

When it comes to knee replacement surgery, one size does not fit all. Total knee replacement, a more common variant, is typically recommended for patients whose arthritis has taken a toll on multiple compartments of the knee. On the flip side, partial knee replacement is tailored for those with ‘unicompartmental’ arthritis, where the damage is localized to one particular section of the knee. Only about 10% of knee replacement patients fall into the category suitable for partial knee replacement, highlighting the specificity required in selecting the right type of procedure.

There are several variations of total knee arthroplasty, including:

• Cruciate-Retaining
• Posterior-Stabilized
• Medially Stabilized
• Hinged types

Each is designed to imitate the knee’s natural movements and is suitable for different severities and patterns of arthritis. Understanding the types of knee arthroplasty procedures—Total Knee Arthroplasty (TKA) and Partial Knee Arthroplasty (PKA)—is the first step toward a pain-free new knee.
