Partial or Unicondylar Knee Replacement (Microplasty) is a minimally invasive procedure designed to treat arthritis that affects only one compartment of the knee—usually the inner (medial) or outer (lateral) side. Instead of replacing the entire knee joint, only the damaged portion is resurfaced, preserving healthy bone, ligaments, and natural knee movement.
This advanced technique offers quicker recovery, reduced pain, and more natural knee function compared to total knee replacement.
When Is Partial Knee Replacement Needed?
You may be recommended for Microplasty if:
Arthritis is limited to a single knee compartment
You experience pain mainly on one side of the knee
Knee ligaments (especially ACL) are intact
You have good range of motion
Daily activities are affected despite physiotherapy and medications
You want a faster recovery with less tissue disruption
This procedure is especially beneficial for younger, active individuals or those with early-stage arthritis.
Benefits of Partial / Unicondylar Knee Replacement
1. Smaller Incision, Less Pain
Minimal soft-tissue disturbance leads to reduced postoperative discomfort.
2. Faster Recovery & Return to Activities
Many patients resume normal walking within days.
3. Preserves Natural Knee Mechanics
Healthy bone, cartilage, and ligaments—including the ACL—are maintained.
4. Greater Range of Motion
Patients often achieve more natural bending and joint movement.
5. Shorter Hospital Stay
Often performed as a short-stay or same-day procedure.
6. Less Blood Loss & Minimal Scarring
A refined surgical technique with fewer complications.

How Microplasty Works
Focused Assessment:
The damaged knee compartment is identified through clinical exams and imaging.Minimally Invasive Approach:
A small incision is used to access only the affected side of the joint.Precision Bone Resurfacing:
Damaged surfaces are removed and replaced with smooth, durable implants.Implant Placement:
Components are positioned to replicate the natural movement of the knee.Preservation of Healthy Structures:
Ligaments and unaffected compartments remain untouched.
Ideal Candidates for Partial Knee Replacement
You may be a suitable candidate if:
Knee pain is localized to one compartment
You have minimal deformity
Your ligaments are stable and functional
You wish to maintain high mobility
You prefer a minimally invasive option over total replacement
A specialist evaluation is essential to confirm eligibility.
Recovery After Microplasty
Recovery is typically faster compared to total knee replacement:
Walk within hours of surgery (for many patients)
Early physiotherapy to restore strength and movement
Minimal swelling due to reduced tissue trauma
Return to daily activities within a few weeks
Low risk of complications with proper follow-up
Most patients enjoy rapid improvement with long-lasting results.
Partial/ Unicondylar Knee Replacement (Microplasty) in Indore with Dr. Devansh Goyal
Partial knee replacement is suitable only when arthritis is limited to one compartment and the ligaments are healthy. Dr. Devansh Goyal assesses this carefully with standing X-rays and examination at Bombay Hospital, Indore, and offers partial (unicondylar) replacement when it is the better long-term choice for you.
Frequently Asked Questions
What is a partial knee replacement?
Only the worn part of the knee (usually the inner compartment) is replaced, while healthy cartilage and ligaments are preserved.
Who is suitable for partial knee replacement?
Patients whose arthritis is limited to one compartment, with stable ligaments, good knee movement and no inflammatory arthritis are usually suitable.
What are the advantages over total knee replacement?
A smaller operation, less blood loss, faster recovery and a knee that often feels more natural, because more of your own knee is kept.
Can a partial knee be converted to a total knee later?
Yes. If arthritis develops in other parts of the knee in future, a partial knee replacement can be converted to a total knee replacement.
How is suitability confirmed?
Standing and stress X-rays, clinical examination and sometimes MRI are used, and the final check is made during surgery.
