What to expect from total knee replacement for knee osteoarthritis

Expect an assessment before surgery, a short hospital recovery or monitored discharge, early movement, and a gradual return to daily activities. The operation replaces damaged joint surfaces; it does not restore a naturally healthy knee or remove every possible source of discomfort.

A surgeon removes the worn surfaces of the thigh bone and shin bone and places artificial components, with a smooth surface between them. The kneecap may also be treated depending on its condition. Knee osteoarthritis is the reason for the operation, while the replacement addresses pain and loss of function caused by joint damage.

Afterward, swelling, bruising, stiffness, and tiredness are common. Pain relief, wound care, and physiotherapy help you bend and straighten the knee and build strength. Progress varies with general health, muscle condition, balance, and the plan made by your surgical team.

Before surgery, arrange transport, help with meals and bathing, and a clear route through your home. Tell the team about medicines, allergies, dental problems, and any skin infection. Follow the instructions about fasting, medicines, exercises, and mobility aids.

After discharge, complete the prescribed exercises without forcing a painful movement. Walk as advised, use your walking aid safely, keep the wound clean and dry as instructed, and attend follow-up visits. Ask when you may drive, work, kneel, climb stairs, or return to sport.

Contact your surgical team promptly for increasing wound redness, drainage, wound opening, fever, worsening pain, or a new inability to move the knee. Seek urgent help for sudden breathlessness, chest pain, fainting, or a painful swollen calf, especially after surgery.

Ask which implant design is planned, what movement goal is realistic for you, how pain will be managed, and which medicines should change around surgery. Clarify the physiotherapy schedule, wound review, warning signs, and the expected timing of work, driving, and stairs.
