Knee replacement surgery is a common surgical procedure designed to replace a damaged or worn-out knee joint with an artificial implant. This surgery is primarily performed to alleviate chronic knee pain and restore mobility, especially in older adults or individuals suffering from degenerative joint diseases like osteoarthritis.
There are two main types of knee replacement surgery: Total Knee Replacement (TKR) and Partial Knee Replacement (PKR). Understanding the differences between these knee replacement surgery options is important, as the choice depends on the severity of joint damage and the patient’s overall health.
Synopsis
Common Knee Conditions That Require Replacement
Several conditions may lead to knee joint damage severe enough to require surgery:
-
Osteoarthritis is the leading cause, involving the gradual breakdown of cartilage which results in painful bone-on-bone contact.
-
Rheumatoid arthritis, an autoimmune disorder, causes joint inflammation and destruction.
-
Post-traumatic arthritis develops after injuries like fractures or ligament damage, accelerating joint wear.
These conditions can affect either one or multiple compartments of the knee joint, which is divided into the medial (inner), lateral (outer), and patellofemoral (front) compartments. The extent and location of damage determine whether a partial knee replacement procedure or a total knee replacement is the best treatment.
Understanding the Procedures
Total Knee Replacement (TKR)
In total knee replacement, the entire knee joint is replaced, including the femur (thigh bone), tibia (shin bone), and patella (kneecap). This surgery is recommended for patients with widespread arthritis affecting most or all compartments of the knee or those with severe deformities.
TKR is the standard treatment for severe, advanced arthritis and is ideal for individuals experiencing persistent pain and reduced knee function throughout the joint.
Partial Knee Replacement (PKR)
The partial knee replacement procedure is less invasive, involving replacement of only the damaged compartment while preserving the healthy parts of the knee joint. This technique involves smaller incisions, less tissue disruption, and often allows for a quicker recovery.
PKR is suitable for patients with arthritis confined to a single compartment, offering the advantage of maintaining more of the knee’s natural structure and movement.
Partial vs Total Knee Replacement: A Side-by-Side Comparison

|
Surgical scope |
Only the affected compartment was replaced |
The entire knee joint was replaced |
|
Recovery duration |
Generally quicker recovery |
Longer rehabilitation required |
|
Ideal candidates |
Arthritis is limited to one compartment |
Extensive arthritis across multiple areas |
|
Implant lifespan |
May be shorter than TKR |
Typically longer-lasting |
|
Pain relief & function |
Good pain relief, more natural movement |
Excellent pain relief and improved mobility |
Knowing the difference between partial and total knee replacement helps patients and doctors decide on the best surgical approach.
Risks and Advantages
Risks
Both TKR and PKR share some potential risks:
-
Risk of infection at the surgical site.
-
Development of blood clots (deep vein thrombosis).
-
Bleeding complications.
-
Possible nerve or blood vessel damage.
-
Implant loosening or failure requiring revision surgery.
-
Persistent pain or knee instability in some cases.
Because TKR is a more extensive surgery, the risk profile may be slightly higher than that of PKR.
Benefits
-
Despite the risks, the benefits are significant:
-
Substantial relief from pain caused by arthritis.
-
Improved knee function and movement.
-
Enhanced ability to perform everyday activities independently.
-
Overall better quality of life.
Hospitals like Manipal Hospitals Pune offer advanced surgical techniques such as minimally invasive procedures and fast-track total knee replacement recovery time programmes, which help reduce complications and promote quicker healing.
Recovery and Post-Operative Care
Recovery from knee replacement surgery is a critical phase for a successful outcome. Although care after both procedures is similar, total knee replacement recovery time is usually longer than after PKR.
-
Hospital stay: Patients typically stay in hospital for 2 to 4 days after surgery. Those undergoing PKR often have a shorter stay.
-
Mobility aids: Crutches or walkers are used initially to assist with walking.
-
Physiotherapy: Early and consistent physical therapy is essential to regain strength and flexibility.
-
Pain and swelling: These symptoms are common but generally improve over time.
-
Recovery timeline: PKR patients may return to normal activities within a few weeks, while TKR patients may require several months to fully recover.
Following the rehabilitation plan and physiotherapy is crucial for regaining full knee function and maximising the benefits of surgery.
Selecting the Right Surgery for You
Choosing between partial vs. total knee replacement depends on various factors:
-
The severity and distribution of knee joint damage.
-
The patient’s age, body weight, and lifestyle.
-
Overall health and presence of other medical conditions.
-
Expectations regarding recovery time and functional outcomes.

FAQ's
Partial knee replacement replaces only the damaged knee compartment, preserving healthy parts. Total knee replacement replaces the entire knee joint. Choice depends on arthritis severity and joint damage.
Partial knee replacement typically has a faster recovery time due to less invasive surgery and quicker rehabilitation compared to total knee replacement.
Patients with arthritis limited to one knee compartment, good overall health, and stable knee ligaments are ideal candidates for partial knee replacement.
Yes, both surgeries carry risks such as infection, blood clots, implant failure, and nerve damage, though total knee replacement generally has higher risk due to its extensive nature.
Yes, Manipal Hospitals Kharadi has expert orthopaedic surgeons with extensive experience in both partial and total knee replacements, offering advanced techniques and personalised care.
