Causes & Symptoms

Non‑Surgical / Lifestyle Care

Many patients improve with a structured, non‑operative plan. Dr. Nakul Shah recommends a personalized mix of the following based on your examination and imaging:

• Activity modification: reduce high‑impact activities; choose cycling, swimming, or elliptical.
• Physiotherapy: quadriceps/hip strengthening, hamstring and calf stretches, gait training, and balance work.
• Weight management: even 5–10% weight loss reduces knee joint load and pain.
• Pain control: paracetamol/acetaminophen or prescribed NSAIDs as appropriate; adjunct topical NSAIDs or capsaicin.
• Bracing and supports: offloading braces for unicompartmental arthritis; patellar trackers if kneecap maltracking.
• Footwear/orthotics: cushioned shoes, medial/lateral wedges when indicated.
• Injections: corticosteroids for short‑term flare relief; hyaluronic acid for select patients; PRP in carefully chosen cases.
• Self‑care: heat for stiffness, ice for swelling, and scheduled rest periods to prevent flares.
• Comorbidity optimization: diabetes control, vitamin D, and bone health assessment.

Treatment & Surgical Options

When is knee replacement considered?

Surgery is considered when pain and functional limits persist despite comprehensive conservative care, X‑rays show advanced joint damage, or deformity/instability compromises safety and mobility.

What is robotic knee replacement?

Robotic‑assisted knee replacement combines 3D planning with intraoperative sensors and haptic guidance. The system helps your surgeon map your knee, protect soft tissues, and execute bone cuts within millimetre accuracy while constantly assessing ligament balance through your range of motion.

How Dr. Nakul Shah performs the procedure

• Personalized planning: Preoperative imaging and live intraoperative mapping build a 3D model of your knee.
• Registration and balancing: Key anatomical landmarks are registered; ligament tension is measured to plan implant size and alignment.
• Haptic‑guided bone preparation: The robotic arm creates precise cuts within defined boundaries to protect surrounding tissues.
• Trialing and fine‑tuning: Trial implants are assessed for stability, alignment, and patellar tracking; adjustments are made in real time.
• Final implantation: Cemented or cementless components are placed depending on bone quality and indications.
• Closure and analgesia: Multimodal pain control and targeted local anaesthesia support early mobilization.

Anaesthesia, duration, and hospital stay

Most patients receive spinal/epidural or general anaesthesia with regional nerve blocks. Surgery typically lasts 60–120 minutes depending on the case. Mobilization usually begins the same day or next morning, with a typical hospital stay of 1–3 days when medically appropriate.

Recovery and rehabilitation

• Day 0–2: Walk with assistance; begin range‑of‑motion and strengthening exercises.
• Week 1–2: Wound check; progress with physiotherapy and independent home exercises.
• Week 3–6: Increase endurance, balance, and functional tasks; many patients resume driving around 4–6 weeks (after medical clearance).
• Week 6–12: Return to light work; continue strength and flexibility training.
• 3–6 months: Ongoing gains in comfort and function; most daily activities feel natural.

Potential risks include blood clots, infection, stiffness, residual pain, implant misalignment/loosening, and rare nerve or vessel injury. Robotic assistance aims to reduce alignment and soft‑tissue errors, but risks cannot be eliminated. Prophylaxis, sterile protocols, and early rehabilitation reduce complications.


How Robotic Surgery is helpful ?

Compared with conventional knee replacement, robotic assistance offers higher accuracy in bone cuts and implant alignment, better soft‑tissue protection through haptic boundaries, and more consistent ligament balancing. Many patients experience smoother early recovery, though long‑term outcomes also depend on surgical expertise, rehabilitation, implant design, and your overall health. Robotic systems may involve higher procedural costs and are not necessary for every patient. Partial (unicompartmental) knee replacement can be an option when arthritis is limited to one compartment, preserving more native bone and ligaments. Total knee replacement addresses multi‑compartment disease and deformity. Both can be performed with robotic assistance; the best choice depends on imaging, exam findings, and your activity goals.
