- Implant choice and recovery expectations are reviewed with the patient
Common patient questions about knee replacement surgery
When is knee replacement needed?
Knee replacement is usually considered when arthritis or joint damage causes severe pain, walking limitation, stair difficulty, and reduced quality of life, and non-surgical care such as medication, physiotherapy, injections, or weight management has not helped enough.
How long is recovery after knee replacement?
Recovery depends on age, general health, muscle strength, and physiotherapy. Many patients walk with support in the early weeks and gradually increase daily activity, while fuller recovery of strength and confidence takes longer.
What care is needed after knee replacement?
Wound care, correct medication use, clot prevention, regular exercises, and planned follow-up are important. Fever, wound redness or discharge, unusual severe pain, or shortness of breath should be checked urgently.
