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.
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.

total length of hospital stay
total length of hospital stay as defined by number of days from date of surgery to date of discharge
Time frame: outcome measure will be taken at 2 weeks postoperatively
Knee Society Score
Knee Society Score. The score is on a scale from 0-100. A higher value represents a better outcome.
Time frame: outcome measure will be taken preoperatively (4-6 weeks prior to date of surgery)
Knee Society Score
Knee Society Score. The score is on a scale from 0-100. A higher value represents a better outcome.
Time frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
WOMAC Score
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
Time frame: outcome measure will be taken preoperatively (4-6 weeks prior to date of surgery)
WOMAC Score
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
Time frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
Active range-of-motion (ROM)
Active ROM (range-of-motion) as measured by a goniometer (range of 0-135 degrees)
Time frame: outcome measure will be taken preoperatively (4-6 weeks prior to date of surgery)
Active range-of-motion (ROM)
Active ROM (range-of-motion) as measured by a goniometer (range of 0-135 degrees)
Time frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively

Incidence of loss of knee motion requiring an MUA (manipulation under anesthesia)
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.
Time frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
Operative Time
Total Operative Time as defined in minutes
Time frame: outcome measure will be taken at 2 weeks postoperatively
Tourniquet time
Total Tourniquet Time is the number of minutes that the tourniquet is inflated, as defined in minutes.
Time frame: outcome measure will be taken at 2 weeks postoperatively
Estimated Blood Loss (EBL)
Estimated Blood Loss as defined by the amount of intraoperative blood loss measured in cubic centimeters (cc).
Time frame: outcome measure will be taken at 2 weeks postoperatively
Number of Participants with postoperative complications
Number of Participants with postoperative complications. A postoperative complication is defined as any diagnosis or condition that necessitates a re-operation or procedure on the surgical knee
Time frame: outcome measure will be taken 6 weeks (± 2 weeks) postoperatively
