Evaluation of Patient Reported Outcomes (PRO) After Total Knee Arthroplasty (TKA) Under Spinal Anesthesia

Evaluation of the Patient Reported Outcomes After Sensor-guided Total Knee Arthroplasty Under Spinal Anesthesia With Limited Motor-block.

The purpose of this study will be to evaluate and compare patients undergoing total knee arthroplasty (TKA) with sensor guidance versus that of a standard technique. Each patient will be assessed for the difference between passive, soft tissue controlled, pressure balance and muscle activated pressure balance.

Inclusion Criteria:

• Patients will be screened for eligibility based on whether they have chronic knee pain as a result of an arthritis-related condition.
• Patient with chronic knee pain who is indicated for total hip or knee replacement surgery
• Patient is at least 50 years of age
• Patient is willing to participate in pre- and postoperative surveys

Exclusion Criteria:

• Failure to complete pre-operative surveys.
• Revision Total Knee Arthroplasty
• Prior ipsilateral knee surgery such as ligament reconstruction or osteotomy
• Contralateral Total Knee Arthroplasty
• Prior tibial plateau fracture
• Ligamentous Insufficiency
• History of fibromyalgia, chronic fatigue syndrome
