Overview
Brief Summary
The goal of this prospective, randomized study is to compare the outcomes of patients undergoing primary TKA after photographing final knee range of motion immediately post-operatively and sharing these photographs with patients at their first follow-up appointment versus a group that does not see a photograph.
Detailed Description
The goal of this prospective, randomized study is to compare the outcomes of patients undergoing primary total knee arthroplasty (TKA) after photographing final knee range of motion immediately postoperatively and sharing these photographs with patients at their first follow-up appointment versus a group that does not see a photograph. The knee will be photographed in maximum flexion and extension. The primary objectives will be to compare the range of motion of the operative knee at 2 weeks and 6 weeks postoperatively. In the investigator's institution, patients who have failed to achieve 90 degrees of flexion at a postoperative period of 6 weeks undergo manipulation of the knee under anesthesia (MUA). The investigators will also measure how many patients require MUA in the photograph group and non-photograph group. MUA will be performed if patients fail to achieve 90 degrees of flexion at 6 weeks post-op.

Eligibility Criteria
Inclusion Criteria
- •Patient is between the age of 22-89
- •Patient is scheduled to undergo a unilateral, cementless primary TKA, secondary to osteoarthritis
- •Patient agrees to participate as a study subject and signs the Informed Consent and Research Authorization documents
- •Patient is able to read and speak English.
Exclusion Criteria
- •Patient is under the age of 22 or over the age of 89

Outcomes
Primary Outcomes
Knee Society Score
Time Frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
Knee Society Score. The score is on a scale from 0-100. A higher value represents a better outcome.
WOMAC Score
Time Frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
WOMAC score. The score is on a scale from 0-100. In contrast to the Knee Society Score, on the WOMAC a lower value represents a better outcome
Active range-of-motion (ROM)
Time Frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
Active ROM (range-of-motion) as measured by a goniometer (range of 0-135 degrees)
total length of hospital stay
Time Frame: outcome measure will be taken at 2 weeks postoperatively
total length of hospital stay as defined by number of days from date of surgery to date of discharge
Operative Time
Time Frame: outcome measure will be taken at 2 weeks postoperatively
Total Operative Time as defined in minutes
Tourniquet time
Time Frame: outcome measure will be taken at 2 weeks postoperatively
Total Tourniquet Time is the number of minutes that the tourniquet is inflated, as defined in minutes.
Incidence of loss of knee motion requiring an MUA (manipulation under anesthesia)
Time Frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
Loss of knee motion is defined as failure to achieve greater than 100 degrees of active flexion. Manipulation under anesthesia is an outpatient procedure performed by orthopedic surgeon to help improve patient's range-of-motion.
Estimated Blood Loss (EBL)
Time Frame: outcome measure will be taken at 2 weeks postoperatively
Estimated Blood Loss as defined by the amount of intraoperative blood loss measured in cubic centimeters (cc).
Secondary Outcomes
- Number of Participants with postoperative complications(outcome measure will be taken 6 weeks (± 2 weeks) postoperatively)
