Knee Pain Chronic
Conditions
Brief summary
Researchers are trying to determine if knee pain can be reduced by proactively protecting the free end of the saphenous nerve versus leaving it in the standard position during total knee arthroplasty.
Detailed description
Subjects scheduled for total knee arthroplasty will be randomized to two arms. One arm will have the standard saphenous nerve neurectomy during their surgery. The other arm will have the same neurectomy procedure with the free end of the nerve tucked into soft tissue to protect the nerve ending.
Interventions
PROCEDUREProphylactic Infrapatellar Saphenous Neurectomy in Primary Total Knee Arthroplasty
Prophylactic infrapatellar saphenous nerve neurectomy will be performed at the same time as the TKA.
