What should you know about Johnson and Johnson total knee replacement?

The procedure removes damaged surfaces of the thigh bone and shin bone and places shaped implant components between them; the kneecap may also be resurfaced. Knee osteoarthritis is one reason people consider this operation when pain and loss of function remain limiting. A cobalt-chrome alloy or titanium implant may form metal parts, while highly cross-linked polyethylene can provide a smooth bearing surface. Bone cement may be used to secure selected components.

Discuss your pain pattern, medical history, medicines, dental issues and home support with the surgical team. Ask how to prepare the skin, arrange transport and practise the exercises recommended before surgery. Afterward, rehabilitation usually works on swelling control, knee straightening, bending, walking and thigh strength. Computer navigation for surgery may assist planning and alignment in selected cases, but the surgeon should explain whether it is relevant to you. Progress is guided by wound review, function and symptoms rather than a fixed timetable.

Follow the discharge plan and contact the surgical team for increasing wound redness, drainage, fever, worsening pain or a sudden reduction in movement. Seek urgent help for chest pain, sudden breathlessness, fainting, or a new painful swelling in the calf.

Ask which implant materials and fixation method are planned, whether the kneecap will be resurfaced, how rehabilitation will be supervised, and which symptoms should trigger an urgent call.
