Understanding Knee Degeneration
In a healthy knee, smooth cartilage caps protect bone endings, allowing effortless gliding. As osteoarthritis progresses, this cartilage wears thin, eventually exposing bare bone.
The resulting bone-on-bone friction leads to deep aching pain, local swelling, morning stiffness, cracking sounds (crepitus), and a gradual bowing of the legs (varus deformity).
Treatment Pathways
High Tibial Osteotomy (HTO)
For younger patients with arthritis confined to the inner knee compartment. Realignment shifts load to the healthy outer side, preserving natural joint structures.
Partial Knee Replacement
For unicompartmental arthritis. Replaces only the worn side, leaving natural ligaments intact for a more natural feel.
Robotic Total Knee Replacement
For advanced bone-on-bone arthritis. Sub-millimeter robotic precision ensures exact implant alignments and faster recoveries.

Pre-Operative Preparation & Clinical Evaluation
A successful orthopaedic outcome starts with meticulous planning. Prior to scheduling any procedure, patients undergo a thorough medical evaluation, including cardiac clearances, complete blood profiles, and tailored joint imaging.
3D Anatomical Mapping
CT scans or high-res MRIs are loaded into the computer software to pre-plan bone cuts and implant size before entering the theatre.
Pre-Hab Exercises
Mild quadriceps and core strengthening exercises are recommended to build muscle tone, which speeds up postoperative recovery.
Post-Operative Rehabilitation & Recovery Pathways
Rehabilitation is a critical phase of recovery. Following surgery, Dr. Vikrant Sinha Roy's team coordinates with clinical physiotherapists to execute structured post-op exercises, facilitating joint mobilization, restoring gait patterns, and strengthening surrounding muscle groups.
Phase 1: Mobilization (Week 1-2)
Focus on wound healing, swelling management, and walking with support.
Phase 2: Strengthening (Week 3-6)
Transitioning to walking independently, climbing stairs, and building muscle flexibility.
Phase 3: Functional Restoration (Week 6+)
Returning to normal daily work, traveling, and light recreational sports.
Patient Success Stories
"After suffering from severe knee osteoarthritis for years, I decided to consult Dr. Vikrant for robotic knee surgery. I walked with support within 24 hours! His empathy, clear explanation of the process, and post-op physiotherapy coordination were outstanding."
— Subrata Chatterjee, 64, Kolkata
"I was diagnosed with bone-on-bone knee arthritis and was terrified of surgery. Dr. Vikrant explained how the robotic surgery would align my joints precisely. Post-surgery, the pain was minimal, and I am back to climbing stairs without any discomfort."
— Minati Sen, 69, Ballygunge
Knee Treatment FAQs
Most patients stand and walk with a walker within 24 hours of surgery. You can typically return to light activities and driving by 3 to 6 weeks, and full independent mobility is achieved within 2 to 3 months.
Yes, robotic-assisted knee replacement surgery is covered by health insurance policies, subject to your policy terms and TPA pre-authorization. Cashless desk support is available at Manipal Hospitals.
High Tibial Osteotomy (HTO) is a joint-preserving surgical technique where the shin bone is realigned to shift pressure away from the damaged side of the knee. This is ideal for active patients with early-stage osteoarthritis.
