Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

A - will be shown their photograph at 2 weeks post-operative.

40-50 arms: patients undergoing a unilateral, cementless primary TKA, secondary to osteoarthritis will be shown a photograph of their knee, photographed in maximum flexion and extension, at 2 weeks postoperatively.

Group Type EXPERIMENTAL

Patient will be shown a photograph of their knee at 2 weeks postop

Intervention Type OTHER

Patients who undergo primary TKA surgery will then be shown a photograph of their knee at 2 weeks postoperative.

B - will not be shown their photograph

40-50 arms: patients undergoing a unilateral, cementless primary TKA, secondary to osteoarthritis will not be shown a photograph of their knee, photographed in maximum flexion and extension, at 2 weeks postoperatively.

Group Type ACTIVE_COMPARATOR

Patient will not be shown a photograph of their knee at 2 weeks postop

Intervention Type OTHER

Patients who undergo primary TKA surgery will not be shown a photograph of their knee at 2 weeks postoperative.
