Introduction
Total knee replacement surgery is a common treatment for severe knee arthritis or injury that causes pain and limits mobility. This procedure involves replacing damaged knee joint surfaces with artificial components, helping restore function and reduce discomfort.
Causes and Indications
- Osteoarthritis causing cartilage loss
- Rheumatoid arthritis leading to joint damage
- Traumatic injuries or deformities affecting the knee
Surgical Procedure
During surgery, the damaged bone and cartilage are removed and replaced with metal and plastic implants designed to mimic natural knee movement. The procedure typically takes 1-2 hours under general or spinal anaesthesia.
Hospital Stay and Postoperative Care
Patients usually stay 3-5 days in hospital. Early mobilisation with the help of a physiotherapist begins within 24 hours to improve circulation and prevent complications.
Rehabilitation and Recovery
Physical therapy is crucial to regain knee strength and flexibility. Full recovery often takes 3-6 months, with gradual return to activities such as walking, climbing stairs, and light exercise.
Patient FAQs
Q1: How long will my knee replacement last?
Most knee replacements last 15-20 years depending on activity levels and overall health.
Q2: When can I walk after surgery?
Most patients start walking with assistance the day after surgery.
Q3: Will I have pain after surgery?
Pain is managed with medication and usually decreases steadily during recovery.
Q4: Can I kneel or squat after knee replacement?
Some patients can kneel or squat after full recovery but this varies and should be discussed with your surgeon.
Q5: What activities should I avoid?
High-impact activities like running or jumping are usually discouraged to protect the implant.
