Why replace your entire knee when only one compartment is worn out? Preserves your healthy ACL & PCL ligaments, natural bone, and un-diseased cartilage with 0.5mm submillimeter 3D robotic precision at Sattva Hospital.
A Targeted Medical Approach to Single-Compartment Osteoarthritis by Dr. Satvik Patel
The knee joint is naturally divided into three distinct functional compartments: the Medial Compartment (inside aspect of the knee), the Lateral Compartment (outer aspect), and the Patellofemoral Compartment (behind the kneecap).
In over 40% to 50% of patients suffering from knee arthritis in India, joint wear is restricted solely to the medial (inner) side. The lateral cartilage and crucial stabilizing ligaments—specifically the Anterior Cruciate Ligament (ACL) and Posterior Cruciate Ligament (PCL)—remain completely healthy and undamaged.
Traditional total knee replacement removes all three compartments regardless of health, sacrificing your natural ACL. Robotic Partial Knee Replacement (UKA) acts like a precision dental crown: we resurface only the damaged compartment, leaving your healthy bone, natural cartilage, and stabilizing ligaments intact.
Bears up to 70% of body weight during walking. Most commonly affected by early osteoarthritis. Robotic UKA targets this specific area.
Outside area of the knee. When healthy, it is preserved completely during robotic partial knee resurfacing.
Area between kneecap and thigh bone. Left fully intact in isolated medial or lateral unicondylar knee replacement.

| Surgical Feature | Robotic Partial Knee (UKA) | Total Knee Replacement (TKA) |
|---|---|---|
| ACL & PCL Ligaments | ✅ Retained & Intact | ❌ ACL Sacrificed / Replaced |
| Natural Joint Feel | ✅ Feels natural like your original knee | Artificial / Synthetic joint feel |
| Surgical Incision | ✅ Minimal (3 to 4 inches) | Standard Open (7 to 8 inches) |
| Healthy Bone Preservation | ✅ Maximum bone preserved (Resurface 1 side) | Resurfacing across all 3 compartments |
| Walking & Discharge | ✅ Walk in 12 hrs; Home in 24 - 48 hrs | Walk in 24 hrs; Home in 3 - 4 days |
| Blood Loss & Pain | ✅ Minimal blood loss & reduced post-op pain | Moderate blood loss & standard recovery |
| Knee Bending & Flexion | ✅ Deep flexion (Easy squatting & sitting) | Good flexion (115° to 125°) |
Submillimeter accuracy without pre-operative CT radiation at Sattva Hospital
During surgery, Dr. Satvik Patel uses optical tracking spheres to paint your bone cartilage surface. The CORI robot creates a real-time, patient-specific 3D digital model of your joint in under 3 minutes. No pre-op CT scan required!
The system measures soft tissue and ligament tension dynamically through your full range of motion. Dr. Satvik calculates exact implant positioning to ensure your ACL and PCL remain perfectly balanced.
The high-speed robotic burr operates with intelligent active boundary control. If the burr moves even 0.5mm beyond the pre-planned surgical boundary, the cutter automatically cuts off—protecting healthy cartilage and ligaments.
The specialized micro-implant is securely seated into the prepared compartment with exact mechanical alignment, providing friction-free motion and extending implant survival up to 20+ years.
Clinical indications evaluated by Dr. Satvik Patel during OPD assessment
Pain, stiffness, or tenderness is felt primarily on the inner (medial) or outer (lateral) side of your knee when walking or standing.
Your anterior and posterior cruciate ligaments are intact and functionally stable, retaining natural knee joint balance.
You can bend your knee past 90 degrees and do not have severe fixed deformity or joint stiffness.
Non-surgical treatments such as physiotherapy, weight management, anti-inflammatories, or PRP injections no longer provide lasting relief.
Individuals seeking a fast recovery, active walking, stair climbing, travel, squatting, and sports participation.
Patients who want a joint that feels authentic and native rather than an artificial replacement.
The world's most clinically proven mobile-bearing partial knee implant. Its free-floating meniscal bearing reduces contact stress and friction, replicating natural knee kinematics.

What to expect after Robotic Partial Knee Replacement at Sattva Hospital
Procedure completed in 45 to 60 minutes under targeted regional anesthesia. Under physical therapy guidance, you stand and walk with full weight-bearing within 12 hours of surgery.
Pain is comfortably managed with multimodal pain management. Patients practice stair climbing and walker navigation. Most patients are discharged home within 24 to 48 hours.
Surgical dressing checked; walking sticks/walkers are phased out. Patients resume office work, driving, domestic activities, and unassisted walking around the house.
Complete return to active lifestyle including long outdoor walks, swimming, cycling, yoga, stair climbing, and travel without joint pain or stiffness.
Got questions about UKA surgery in Ahmedabad? Dr. Satvik Patel provides expert clinical answers.
Robotic Partial Knee Replacement (Unicondylar Knee Arthroplasty - UKA) is an advanced, targeted surgical procedure that resurfaces only the damaged compartment of your knee joint (usually the inner/medial side). Unlike total knee replacement, it leaves your healthy bone, un-diseased cartilage, and crucial ACL and PCL stabilizing ligaments intact.
The key medical differences include:
Yes. If arthritis develops in the remaining compartments 15 to 20 years later, converting a partial knee replacement to a total knee replacement is very straightforward. Because minimal bone was removed during the primary robotic partial knee surgery, standard primary total knee components can usually be utilized.
No! The CORI™ 3D robotic system is completely imageless. It builds a high-definition 3D digital model of your joint inside the operating theatre during surgery. This saves you from pre-operative CT scan costs, extra hospital visits, and unnecessary radiation exposure.
Modern robotic partial knee implants have an exceptional lifespan. With 0.5mm submillimeter robotic accuracy placing implants at ideal mechanical alignment, stress distribution is optimized. International joint registry data demonstrates implant survivorship of 15 to 20+ years in over 90-95% of patients.
Post-operative pain is substantially lower than total knee replacement. Because surgery is minimally invasive and avoids cutting healthy bone or ligaments, surgical trauma is minimized. Combined with multimodal regional nerve blocks, most patients experience only mild, manageable discomfort.
Under the supervision of Dr. Satvik Patel's physical therapy team, patients stand and walk full weight-bearing within 12 hours of surgery. Stair climbing is routinely mastered on Day 1 or Day 2 prior to hospital discharge.
Yes! Inner side knee pain is the classic symptom of medial compartment osteoarthritis. If your X-rays confirm single-compartment cartilage wear and your ligaments are intact, you are likely an excellent candidate for robotic UKA.
Absolutely. Preserving your natural ACL and PCL retains your joint's natural proprioception (spatial position awareness). Patients enjoy smooth deep knee flexion for squatting, sitting cross-legged, walking, swimming, cycling, and playing golf.
