The knee arthroplasty module is one of five modules in the PhDx® Orthopaedic software. It includes all tools necessary for clinicians to track and report outcomes on knee arthroplasty procedures. Designed with a physician’s needs in mind, the knee arthroplasty module tracks patient, clinical, functional status, patient satisfaction, return to work, and home program compliance data sets.

The following are survey instruments included in the module:

• Patient Information: Patient demographic information and baseline pain measurement and pain intensity values.
• Initial Clinical Assessment: Questions regarding the clinical condition-range of motion, weight bearing status, neuropathies, pain medication and medical history of the patient.
• SF12v2TM: The survey measures eight categories of physical and emotional health, which indicates the impact poor health and pain have on physical and social activities.
• Knee Society Clinical Rating Scale: Combines ratings in the areas of pain, function (gait and functional activities), walking support and range of motion into Knee and Function Scores.
• Knee Arthroplasty Surgical Summary: Collects data regarding the surgical procedure performed and cost driver information. Also includes prosthesis information and radiographic report on implant.
• Follow-Up Clinical Assessment: Collects information on the patient's clinical condition such as range of motion, weight bearing status, neuropathies, pain medications, any post-operative complications, and implant component position and alignment (if applicable) at the time of visit.
• Patient Satisfaction with Services: Asks about patient satisfaction with the care received at the facility where the surgery was performed.
• Patient Satisfaction with Results: Collects information regarding the patient's satisfaction with results of the surgery, the patient's pain, intensity data, and return to work information.
