What should you know about partial total knee replacement?

Partial replacement is generally considered when wear is mainly confined to one knee compartment and the remaining joint surfaces and supporting ligaments are functioning well. Knee Osteoarthritis can cause pain, stiffness and reduced confidence on stairs, but symptoms alone do not decide whether partial replacement is appropriate. Examination and imaging help the surgeon map the affected area.

The implant may combine metal and a durable plastic bearing. Depending on the design, materials can include Cobalt-Chrome Alloy, Highly Cross-Linked Polyethylene or Titanium Implant, and Bone Cement may be used to secure components. Computer Navigation for Surgery can help plan alignment and guide bone preparation in some settings.

Before surgery, review medicines, dental concerns, mobility at home and plans for transport and support. Afterward, early movement and a structured rehabilitation programme help restore bending, strength and walking control. Your team will set limits for wound care, driving, work and stairs. Track swelling, pain and function rather than judging recovery by a single day. Tell the team if exercises repeatedly cause sharp pain or the knee loses function.

Contact the surgical team promptly for increasing wound redness, drainage, feverish illness, calf swelling or pain, new shortness of breath, or a sudden inability to bear weight. Urgent assessment is needed for chest pain, severe breathlessness, a cold or numb foot, or a knee that becomes suddenly locked or visibly displaced.

Ask which compartment is affected, why partial rather than total replacement is being considered, what implant materials are planned, and how ligament condition affects the choice. Clarify expected milestones for walking, stairs, driving and return to work.
