This simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement. The knee joint is made up of 3 compartments, the patellofemoral and medial and lateral compartments between the femur and tibia (i.e. the long bones of the leg). Often only one of these compartments wears out, usually the medial one. If you have symptoms and X-ray findings suggestive of this then you may be suitable for this procedure.
A total knee replacement (TKR) or total knee arthroplasty is a surgery that resurfaces an arthritic knee joint with an artificial metal or plastic replacement parts called the ‘prostheses’.
This means that part or all of your previous knee replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone and hence is difficult to describe in full.
All procedures require medical clearance by an internist at HSS which must be done within 28 days prior to your surgery date. We will coordinate these appointments as well as an educational class.
We recommend stopping use of all anti-inflammatory, fish oil supplements, and other blood thinning medications one week prior to surgery. Your clearing doctor will make recommendations regarding other prescription medications.
Your hospital course will entail admission from 1-2 days. Once you are cleared by therapy you can be discharged to home with provided visiting nurse services and physical therapy services at home. This will be followed by outpatient Physical Therapy. Your initial follow-up will be six weeks postoperative.
On average your return to work recovery will be approximately six to eight weeks, depending on individual recovery. The majority of patients will be able to resume most sporting activities in twelve weeks post op.
