What should you know about total knee replacement operation?

The surgeon removes worn surfaces from the thighbone and shinbone, prepares the kneecap when needed, and places metal and durable plastic parts that let the knee bend and straighten. The components may be fixed with bone cement or designed for bone growth around the implant. Knee osteoarthritis is a common reason for this operation when pain, stiffness, or reduced movement continues despite non-surgical care.

Arrange help with meals, bathing, and transport, and clear walking routes at home before admission. Your team may ask you to practise exercises, review medicines, and plan physiotherapy. Early movement, prescribed exercises, wound care, and using a walking aid as instructed support a gradual return to daily activities. Recovery differs between people, so follow the plan given for your knee and general health.

Contact your surgical team promptly for increasing wound redness, drainage, fever, worsening pain, or new calf swelling. Seek urgent help for sudden breathlessness, chest pain, fainting, or a cold, pale, or numb foot. These symptoms need assessment rather than waiting for the next appointment.

Which implant components and fixation method are planned? When should I begin physiotherapy, use stairs, drive, and return to work? Which symptoms should lead me to call the hospital?
