Feasibility of Outpatient Total Knee Arthroplasty

Consecutive patients presenting for elective TKA at the General (Dr. Dervin) will be approached for enrollment.

Dr Dervin will present the study to their patients who are appropriate for the study when first confirmed for joint replacement after clinic assessment. If the patient has indicated that they are interested, the surgeon will inform the research coordinator who will then continue the consenting process. The research coordinator will confirm patient's eligibility to ensure that all inclusion and no exclusion criteria are met. The study will be explained in detail to qualify patients and they will be provided with a copy of the consent form. The consent form will also provide a clause of confidentiality informing patient privacy. All questions will be answered. Patients may also talk to the investigators with any additional questions.

Patients will be advised preoperatively about an accelerated path while in hospital that will share many attributes of the standard TOH care map,but with several additions, chosen to help reduce pain and hemarthrosis, both felt to be the major impediments to faster recuperation.

1. Surgery will be performed with a muscle sparing subvastus approach, chosen because of evidenced decreased pain.
2. Tranexamic acid ( 10 mg/kg) intravenously will be administered to further reduce blood loss at time of tourniquet deflation.
3. The "Game Ready" cold - compression device will be used post operatively to help reduce pain and minimize swelling.
