ORTHOPAEDIC · CONDITION GUIDE
Knee Osteoarthritis
A degenerative condition in which the cartilage cushioning the knee joint slowly wears away, causing bones to rub against each other — leading to pain, stiffness, swelling, and reduced mobility.
ABOUT THIS CONDITION
What is Knee Osteoarthritis?
Knee osteoarthritis is one of the most common joint conditions, where the protective cartilage inside the knee gradually wears away. As cartilage deteriorates, the bones begin to rub directly against each other, causing persistent pain, swelling, stiffness, and reduced mobility. It typically develops after the age of 50, though it can occur earlier due to previous injuries, excess weight, or prolonged physical strain. The condition may affect one or both knees and can range from mild discomfort to severe disability that affects walking, climbing stairs, or sitting comfortably. Dr. Sai Kishan Sirasala specialises in comprehensive knee osteoarthritis treatment at Lux Hospitals, from conservative management to advanced robotic knee replacement surgery.

- Excess body weight placing increased pressure on the knee joint
- Repetitive stress from physical labour, sports, or prolonged standing
- Genetic predisposition or underlying inflammatory joint conditions
- Prior knee fractures or surgeries leading to cartilage damage

Rehabilitation & Recovery
A structured physiotherapy programme begins within 24 hours after surgery. Most patients walk with support in days and resume daily activities within 6–8 weeks.
AVAILABLE TREATMENTS
Treatment Options
Total Knee Replacement (TKR)
The worn-out surfaces of your knee are removed and replaced with metal and plastic implants. The most effective solution for severe arthritis.
Partial Knee Replacement
Only the damaged part of your knee is replaced — your healthy bone, cartilage, and ligaments are kept intact. Recovery is faster and feels more natural.
Revision Knee Replacement
If your previous knee replacement has worn out, loosened, or stopped working well, this surgery replaces or repairs those implants.
