Partial knee replacement is one of the most advanced solutions available today for patients living with chronic knee pain. Unlike total knee replacement, the partial knee replacement procedure only considers the damaged compartment of the knee, preserving more of your natural bone, ligaments, and cartilage.

With smaller incisions, faster recovery, and improved outcomes, it’s no surprise that many people want to know: Who is a candidate for partial knee replacement?

This blog will explore what makes someone eligible, the pros and cons of partial knee replacement, recovery expectations, and how to recognise potential complications.

What Is a Partial Knee Replacement?

Partial knee replacement, also called unicompartmental knee arthroplasty (UKA), involves resurfacing only the worn-out or arthritic portion of the knee joint. The procedure may target the inner (medial), outer (lateral), or kneecap (patellofemoral) compartment.

Patients often experience a knee that feels more natural by leaving healthy tissue and ligaments intact.

Who Is a Candidate for Partial Knee Replacement?

The ideal candidate for this surgery is a person with osteoarthritis limited to one part of the knee, intact ligaments, and good overall health.

Specific factors include:

Persistent pain and stiffness despite conservative treatment (medications, injections, physiotherapy)
Arthritis confined to only one compartment of the knee
Stable knee ligaments (ACL, PCL, MCL, LCL)
Adequate range of motion (usually more than 90°)
Minimal deformity or misalignment
Healthy body weight

Who May Not Be a Candidate?

Some patients are unsuitable due to conditions that affect the whole knee or compromise surgical success. These include:

Advanced osteoarthritis or rheumatoid arthritis affecting multiple compartments
Severe obesity, which increases implant wear and risk of revision
Significant deformity (varus or valgus >10°)
Active infections or poorly controlled medical conditions
Severe stiffness or loss of knee function

Other surgical options, such as complete joint replacement, may be considered for many ineligible patients.

Pros and Cons of Partial Knee Replacement

Like any surgery, this procedure has benefits and limitations.

Advantages of partial knee replacement:	Disadvantages of partial knee replacement:
Smaller incision and less invasive than total replacement Faster recovery and shorter hospital stay Preserves healthy bone and ligaments More natural knee function post-surgery Lower risk of infection and blood loss	Not suitable for widespread arthritis Risk of needing revision surgery if arthritis spreads Limited correction for severe deformities May not relieve kneecap pain if that compartment is also affected

Life After Partial Knee Replacement

Patients often report a dramatic improvement in mobility and quality of life. You can return to daily routine activities, enjoy low-impact exercises like cycling or swimming, and experience reduced pain.

3 Months After Partial Knee Replacement

By the three-month mark, many patients can walk unaided, have regained a significant range of motion, and are back to light work and hobbies.

However, progress still depends on consistent physiotherapy and following medical guidance.

What Not to Do After Partial Knee Replacement

To protect your new joint, avoid:

High-impact sports like running or jumping
Excessive twisting or pivoting
Heavy lifting in the early recovery phase
Driving before you’re medically advised

Success Rate of Partial Knee Replacement

Research shows that partial knee replacement success rates are high, with many implants lasting 10–15 years or more. Outcomes are best in carefully selected patients who meet eligibility criteria.

Partial Knee Replacement Failure Symptoms

Although rare, it’s important to recognise warning signs of failure, which may include:

Persistent or worsening pain
Swelling or stiffness that does not improve
Instability or giving way of the knee
Grinding or clicking sounds
Signs of infection (redness, warmth, discharge)

If you experience these, seek immediate medical review.

FAQ's

How do you qualify for a partial knee replacement?

You qualify if your arthritis affects only one knee compartment, your ligaments are intact, and you have not responded to conservative treatments.

What is the average age for a partial knee replacement?

Traditionally performed in patients over 60, advanced techniques make it suitable for younger individuals with localised disease.

What are the symptoms of needing a partial knee replacement?

Common signs include chronic knee pain, swelling, stiffness, and difficulty climbing stairs or standing for long periods.

How do I know if I need a full or partial knee replacement?

A specialist determines this using physical examination and imaging. If arthritis is limited, a partial replacement may be recommended. If the entire knee is affected, a full replacement is often necessary.
