If you’ve been experiencing knee pain or limited mobility due to arthritis, injury, or other joint conditions, knee replacement surgery might be a solution you’re considering. It’s a common procedure that helps millions of people regain the ability to move comfortably and improve their quality of life. But with two main types of knee replacements – partial and total – it’s essential to understand the key differences between them. In this blog, we’ll break down both types of surgeries, explain who’s a good candidate for each, and help you determine which one might be the best fit for you.
What is Knee Replacement Surgery?
Knee replacement surgery is a procedure where damaged parts of the knee joint are replaced with artificial components. The aim is to reduce pain and restore normal knee function. There are two main types of knee replacements: partial knee replacement and total knee replacement. These surgeries are designed to help individuals who suffer from severe knee pain due to conditions like osteoarthritis, rheumatoid arthritis, or injury.
What is Partial Knee Replacement?
Partial knee replacement, also known as unicompartmental knee arthroplasty, involves replacing only one part of the knee joint. There are three main compartments in the knee: the medial, lateral, and patellofemoral. In partial knee replacement, the surgeon replaces the damaged compartment while leaving the rest of the knee intact.
This type of surgery is often recommended for patients whose knee damage is limited to one compartment. For instance, if arthritis or injury has affected only the inner part of the knee, a partial knee replacement might be a better fit. One of the advantages of partial knee replacement is that the recovery time is generally quicker since the surgery is less invasive. Additionally, it may feel more natural since more of the knee joint remains untouched.
What is Total Knee Replacement?
Total knee replacement, also called total knee arthroplasty, involves replacing all three compartments of the knee with artificial components. This procedure is more commonly performed when knee damage is widespread and affects most or all parts of the knee joint. In this surgery, both the damaged cartilage and bone are removed and replaced with metal and plastic components that mimic the knee’s natural movement.
Total knee replacement is often recommended for patients with extensive arthritis or significant knee deformities. This surgery aims to relieve pain and improve knee function, but it comes with a longer recovery period compared to partial knee replacement.
Key Differences Between Partial and Total Knee Replacements
1. Scope of Surgery
Partial Knee Replacement: Only one compartment of the knee is replaced, preserving the other two healthy compartments.
Total Knee Replacement: All three compartments are replaced, resulting in a more extensive procedure.
2. Recovery Time
Partial Knee Replacement: Because less tissue is removed and the surgery is smaller, patients typically experience a quicker recovery time. Most can return to their normal activities in about 6 weeks.
Total Knee Replacement: Recovery is more extensive, and it can take anywhere from 3 to 6 months to fully recover. Physical therapy is usually required to help regain strength and mobility.
3. Pain and Functionality
Partial Knee Replacement: Since less of the knee is altered, many patients report that partial knee replacements feel more natural. However, if arthritis develops in the remaining compartments over time, a total knee replacement may be needed later.
Total Knee Replacement: Although this procedure is more invasive, it often provides a more long-term solution, particularly for patients with widespread knee arthritis.
4. Cost
Partial Knee Replacement: This surgery tends to be less expensive since it is less invasive and requires less hospital time.
Total Knee Replacement: The cost of total knee replacement can be higher due to the complexity of the surgery and the longer hospital stay.
Benefits and Risks of Partial Knee Replacement
Benefits:
- Less pain and faster recovery due to the smaller incision.
- Preservation of healthy knee tissues means more natural movement.
- Patients may experience less post-surgery stiffness and may find it easier to return to daily activities like walking or driving.
Risks:
- While it’s less invasive, there’s a chance that arthritis can develop in the remaining parts of the knee, requiring additional surgeries in the future.
- Partial knee replacements have a slightly higher chance of needing a revision surgery down the road compared to total knee replacements.
Benefits and Risks of Total Knee Replacement
Benefits:
Provides long-term pain relief, particularly for patients with arthritis or damage to multiple areas of the knee.
Greater chance of lasting function for the knee, improving walking, climbing stairs, and other everyday activities.
Risks:
The recovery time is longer and requires more physical therapy.
Although complications are rare, there are risks of infection, blood clots, or issues with the artificial joint over time.
Which Knee Replacement Surgery is Right for You?
The choice between partial and total knee replacement often depends on several factors, such as:
- The extent of damage to your knee: If arthritis or injury affects just one compartment of the knee, partial knee replacement could be the better option.
- Your age and activity level: Younger, more active individuals with localized knee issues may benefit from partial knee replacement, while those with extensive knee damage may require a total knee replacement.
- The condition of your knee: If you have multiple knee issues, such as damage to cartilage, ligaments, or bones, a total knee replacement might provide the best long-term results.
An orthopedic surgeon will assess your knee condition, discuss your lifestyle, and help you decide which option is best suited for you.
Both partial and total knee replacement surgeries can significantly improve your quality of life by reducing pain and increasing mobility. The best option depends on the extent of knee damage, your health, and personal preferences. To determine which procedure is right for you, it’s essential to consult with an experienced orthopedic surgeon who can guide you through the decision-making process.

FAQ
Q1. What are the key differences between partial and total knee replacement?
Partial knee replacement fixes only the damaged part, while total knee replacement replaces the whole knee. Partial recovery is quicker, but total replacement is better for extensive damage.
Q2. Can I return to sports after knee replacement surgery?
You can return to low-impact activities, but high-impact sports like running are generally not recommended.
Q3. Is partial knee replacement less expensive than total knee replacement?
Yes, partial knee replacement is typically less costly due to a smaller procedure and shorter hospital stay.
