How long is recovery after unicondylar knee replacement?

Most patients walk without support within 2 to 4 weeks and return to most daily activities by 6 to 10 weeks — significantly faster than total knee replacement. Full functional recovery is typically achieved by 3 months.

What is the difference between unicondylar and total knee replacement?

Unicondylar replacement resurfaces only one damaged compartment, preserving healthy tissue. Total knee replacement resurfaces all three compartments. UKR is less invasive with faster recovery but is only suitable for single-compartment arthritis with intact ligaments.

How long does unicondylar knee replacement last?

Unicondylar knee implants are designed to last 10 to 15 years or longer in appropriately selected patients. If arthritis progresses to other compartments over time, conversion to total knee replacement is possible.

Unicondylar knee replacement surgery — minimally invasive partial knee arthroplasty for single compartment arthritis in Jaipur

Partial Knee Replacement · Jaipur

Unicondylar Knee Replacement in Jaipur

Not all knee arthritis requires a total joint replacement. When arthritis is confined to a single compartment of the knee — most commonly the medial (inner) side — unicondylar knee replacement offers a minimally invasive solution that targets only the damage, preserving everything healthy.

Dr. Harish Talreja performs unicondylar (partial) knee replacement at Manipal Hospital Jaipur — a leading orthopaedic specialist in Jaipur with extensive joint replacement expertise. The result is a more natural-feeling knee, smaller incision, and significantly faster return to daily life compared to total knee replacement.

Smaller Incision

5–8 cm vs 8–12 cm for total knee

Faster Recovery

Return to activities in 6–10 weeks

Natural Knee Feel

Healthy tissue and ligaments preserved

Less Blood Loss

Understanding the Procedure

What is Unicondylar Knee Replacement?

Unicondylar knee replacement (UKR) — also called partial knee replacement or unicompartmental knee arthroplasty — is a procedure in which only the single damaged compartment of the knee is resurfaced with an artificial implant.

The knee has three compartments: medial (inner), lateral (outer), and patellofemoral (front). In UKR, only the worn compartment — most commonly the medial — is replaced. The cruciate ligaments, healthy cartilage, and natural bone in the remaining compartments are completely preserved.

This targeted approach restores the knee's natural biomechanics more closely than total replacement — many patients describe their replaced knee as feeling more natural after UKR than after total knee replacement.

Medial Compartment (Most Common)

The inner compartment — most commonly affected by osteoarthritis. Medial UKR is the most frequently performed partial knee procedure.

Lateral Compartment

The outer compartment. Lateral unicondylar replacement is less common but is performed for isolated lateral compartment arthritis.

Preserved Ligaments

The ACL, PCL and collateral ligaments are retained — enabling more natural joint mechanics and proprioception after surgery.

Implant Components

A femoral component and tibial baseplate with polyethylene insert are used — smaller and less disruptive than total knee implants.

Patient Selection

Who is a Good Candidate for Unicondylar Knee Replacement?

Patient selection is the most critical factor in UKR success. A thorough clinical examination and weight-bearing X-rays — and MRI where needed — are essential to determine eligibility.

✓ Suitable Candidates

✓

Isolated single-compartment knee osteoarthritis (usually medial)

✓

Intact anterior cruciate ligament (ACL) confirmed on examination or MRI

✓

Healthy cartilage in the opposite compartment and patellofemoral joint

✓

Correctable varus or valgus deformity of less than 10–15 degrees

✓

Good range of knee motion — at least 90–100 degrees of flexion

✓

Full extension achievable (fixed flexion deformity less than 5–10 degrees)

✗ Not Suitable — TKR Recommended

✗

Multi-compartment arthritis affecting two or three compartments

✗

Absent or deficient ACL — the ligament is required for UKR stability

✗

Significant fixed deformity greater than 15 degrees varus or valgus

✗

Inflammatory arthritis (rheumatoid, psoriatic) affecting the whole joint

✗

Significant patellofemoral arthritis with anterior knee pain

✗

Severely limited range of motion or advanced fixed flexion deformity

Surgical Process

How Unicondylar Knee Replacement is Performed

The procedure typically takes 1 to 1.5 hours under spinal or general anaesthesia. Most patients begin walking on the same day as surgery.

Pre-Operative Assessment

Weight-bearing X-rays, MRI (where needed), blood tests and anaesthesia review. Implant sizing planned to match the individual knee anatomy.

Anaesthesia and Preparation

Spinal anaesthesia preferred. Smaller tourniquet and incision compared to total knee. Strict sterile technique throughout.

Single Compartment Resurfacing

Only the worn bone and cartilage in the single damaged compartment are removed. A precisely fitted femoral and tibial component are implanted, preserving all healthy structures.

Day 1 Rehabilitation

Wound closed in layers. Physiotherapy begins on Day 1 — standing, walking with support and early range-of-motion exercises start the same day.

Rehabilitation

Recovery After Unicondylar Knee Replacement

One of UKR's most significant advantages over total knee replacement is the dramatically faster recovery timeline. A structured physiotherapy programme starting on Day 1 ensures optimal strength and mobility are regained as quickly as possible.

Day 1

Standing and First Walk

Most patients stand and take supported steps on the day of or the day after surgery. Physio exercises begin immediately.

Days 2–3

Discharge Home

Most patients are discharged within 2 to 3 days. Wound care, home exercises, and gradual weight-bearing continue at home.

Weeks 2–4

Walking Without Aids

Most patients walk independently without a walker or crutches by 2 to 4 weeks — significantly earlier than total knee replacement.

Weeks 6–10

Return to Full Daily Activities

Return to driving, office work, climbing stairs and most social activities. Strength and confidence continue to improve.

Month 3

Full Functional Recovery

Most patients achieve complete functional recovery — including light recreational activities — by 3 months post-surgery.

Day 1

Walking with support after surgery

2–4 Wks

Independent walking without aids

6–10 Wks

Return to daily activities

10–15 Yrs

Why Choose UKR

Benefits of Unicondylar Knee Replacement

For appropriately selected patients, unicondylar knee replacement offers distinct clinical advantages over total knee replacement.

Minimally Invasive

Smaller incision, less tissue disruption and reduced blood loss compared to total knee replacement — enabling faster healing and less post-operative discomfort.

Faster Recovery

Return to daily activities, driving, and light work in 6 to 10 weeks — significantly faster than the 3 to 6 month total recovery required after TKR.

More Natural Feel

Preserving the ACL, PCL and healthy cartilage maintains the knee's natural proprioception — many patients report a more natural-feeling knee than after total replacement.

Targeted Repair

Only the damaged compartment is replaced — all healthy bone, cartilage and ligaments in the rest of the knee are completely preserved.

Less Blood Loss

Smaller operative field means significantly less blood loss during surgery — reducing the risk of transfusion and aiding faster post-operative recovery.

Shorter Hospital Stay

Most patients are discharged in 2 to 3 days — a day or two earlier than after total knee replacement — allowing return home and recovery in familiar surroundings.

Upgradeable if Needed

If arthritis progresses to other compartments in later years, unicondylar replacement can be converted to total knee replacement — the best outcome is not compromised.

Bone-Preserving

Less bone is removed than in total knee replacement — a significant advantage, particularly for younger, more active patients who may require future surgery.

Frequently Asked Questions

Unicondylar Knee Replacement — Common Questions

Unicondylar knee replacement (UKR), also called partial knee replacement, is a minimally invasive procedure that resurfaces only the single damaged compartment of the knee — most commonly the medial (inner) compartment — while preserving the healthy bone, cartilage and ligaments in the rest of the joint. It is distinct from total knee replacement, which replaces all three compartments.

Ideal candidates have isolated single-compartment knee osteoarthritis (usually medial), an intact anterior cruciate ligament (ACL), healthy cartilage in the other compartments, correctable deformity of less than 15 degrees, and good range of motion. Inflammatory arthritis, absent ACL, or multi-compartment disease are indications for total knee replacement instead. A detailed clinical and X-ray assessment determines eligibility.

Recovery after UKR is significantly faster than after total knee replacement. Most patients walk without support within 2 to 4 weeks and return to most daily activities — including driving, climbing stairs, and office work — by 6 to 10 weeks. Full functional recovery is typically achieved by 3 months. This is considerably faster than the 3 to 6 month full recovery timeline for total knee replacement.

Unicondylar replacement resurfaces only one damaged compartment, preserving all healthy tissue and both cruciate ligaments. Total knee replacement resurfaces all three compartments and is appropriate for more widespread disease. UKR offers a less invasive approach with faster recovery and a more natural knee feel — but is only suitable for carefully selected patients with single-compartment arthritis and an intact ACL.

Unicondylar knee implants are designed to last 10 to 15 years or longer in appropriately selected patients. Long-term registry data shows excellent survival rates at 10 years in well-selected patients. If arthritis progresses to other compartments over time, conversion to total knee replacement is a straightforward procedure and produces good outcomes.

Due to the smaller incision and less tissue disruption, post-operative pain after UKR is generally less than after total knee replacement. Most patients manage comfortably with oral pain medications in the first few days. The Day 1 mobilisation protocol at Manipal Hospital Jaipur ensures early movement — which itself reduces post-operative stiffness and pain.

The cost depends on the implant type and brand selected, hospital stay duration, and any associated tests. An accurate estimate is provided after consultation and clinical assessment. Most major health insurance policies in India — including CGHS and RGHS for Rajasthan government employees — cover unicondylar knee replacement surgery.
