Overview
UniCondylar Replacement, also known as Unicompartmental Knee Replacement (UKR), is a minimally invasive knee surgery designed to replace only the damaged portion of the knee joint instead of the entire knee.
The knee joint is divided into three compartments:
- Medial (inner)
- Lateral (outer)
- Patellofemoral (front)
When osteoarthritis or localized cartilage damage affects only one compartment, a UniCondylar Replacement can be an effective, bone-preserving surgical option.

How UniCondylar Replacement Differs from Total Knee Replacement
Many patients assume knee replacement always means replacing the entire joint. However, that is not always necessary.
| UniCondylar Replacement | Total Knee Replacement |
|---|---|
| Replaces only one damaged compartment | Replaces entire knee joint |
| Smaller incision | Larger incision |
| Preserves healthy bone & ligaments | More bone removed |
| Faster recovery | Slightly longer recovery |
| More natural knee movement | Artificial joint mechanics |
Who is a Good Candidate for UniCondylar Replacement?
Not every patient with knee pain qualifies for this surgery. Ideal candidates typically have:
- Osteoarthritis limited to one compartment
- Intact ligaments (especially ACL)
- Minimal knee deformity
- Stable knee joint
- Good range of motion
- Failure of non-surgical treatments like physiotherapy or injections
Patients with advanced arthritis affecting multiple compartments may require total knee replacement instead.
Benefits of UniCondylar Replacement
One of the major reasons patients prefer UniCondylar Replacement is its conservative and tissue-preserving nature.
Key Benefits:
✔ Smaller surgical incision
✔ Less blood loss
✔ Reduced post-operative pain
✔ Faster hospital discharge
✔ Quicker rehabilitation
✔ More natural knee movement
✔ Preservation of healthy bone and ligaments
Dr. Ashish Jain emphasizes that preserving natural knee anatomy often results in better long-term functional outcomes for selected patients.
Surgical Procedure Overview
The UniCondylar Replacement procedure involves:
- Detailed pre-operative evaluation (X-rays, MRI if required)
- Removal of damaged cartilage and bone from the affected compartment
- Placement of precision-designed implant components
- Preservation of remaining healthy joint structures
The surgery is typically completed within a short operative duration and patients are encouraged to mobilize early.
At KneeJointReplacement, advanced techniques and structured recovery protocols are followed to ensure patient safety and optimal results.
Recovery After UniCondylar Replacement
Recovery is generally faster compared to total knee replacement.
What to Expect:
- Walking with support within 24–48 hours
- Shorter hospital stay
- Faster return to daily activities
- Physiotherapy guidance for strength and mobility
- Gradual improvement over 4–6 weeks
Most patients experience significant pain relief and improved joint function within weeks.
Longevity of UniCondylar Implants
Modern implants used in UniCondylar Replacement are designed for durability. With proper patient selection and surgical precision, implants can last 15 years or longer.
However, outcomes depend on:
- Patient weight
- Activity level
- Surgical technique
- Post-operative care
- Regular follow-ups
Dr. Ashish Jain ensures thorough evaluation before recommending this surgery to maximize implant longevity.
Is UniCondylar Replacement Safe?
Yes. When performed by an experienced knee specialist, UniCondylar Replacement is a safe and effective procedure with high patient satisfaction rates.
However, like all surgeries, it requires:
- Proper case selection
- Experienced surgical expertise
- Structured rehabilitation
- Regular monitoring
Choosing a specialized knee surgeon is critical for optimal outcomes.

Conclusion
UniCondylar Replacement is an excellent option for patients with localized knee arthritis who wish to preserve as much of their natural joint as possible. It offers quicker recovery, improved function, and less invasive treatment compared to total knee replacement.
FAQs
1. What is UniCondylar Replacement?
Ans. It is a partial knee replacement surgery that replaces only the damaged compartment of the knee joint.
2. How long does recovery take?
Ans. Most patients resume daily activities within 4–6 weeks, depending on individual health and rehabilitation.
3. Is UniCondylar Replacement better than total knee replacement?
Ans. It is better for patients with single-compartment damage. However, total knee replacement may be required for advanced arthritis.
4. Will I be able to walk normally after surgery?
Ans. Yes. Most patients regain near-normal knee function with proper rehabilitation.
5. How do I know if I am eligible?
Ans. A detailed evaluation by an experienced knee specialist like Dr. Ashish Jain is necessary to determine suitability.
