Brief Summary
This is a prospective cohort study comparing standard inpatient (overnight hospital stay) total knee arthroplasty with same day discharge. Patients who are medically well and have a good support structure at home will be recruited. This study will compare patient satisfaction and costs from the perspectives of the Ministry of Health, the institution, society and the patient.

Study Arms (2)
Outpatient
EXPERIMENTALPatients in the outpatient group (same day discharge following TKA) are discharged the same day following surgery. All patients are required to meet the discharge criteria to be sent home (i.e., capable of using crutches, relatively free of pain, free of nausea and vomiting, free of excess bleeding, alert and oriented, given take-home medications, and in the company of a caregiver).
Inpatient
ACTIVE COMPARATORPatients in the inpatient group (following day discharge following TKA) stay in the hospital overnight and then are discharged home the next day. All patients are required to meet the discharge criteria to be sent home (i.e., capable of using crutches, relatively free of pain, free of nausea and vomiting, free of excess bleeding, alert and oriented, given take-home medications, and in the company of a caregiver).
Interventions
Patients in the outpatient group will be discharged from the hospital the same day of surgery following a total knee arthroplasty
Patients in the inpatient group will be discharged from the hospital the following day after a total knee arthroplasty
