Background summary
Anterior knee pain occurs in up to 31% of patients after total knee arthroplasty without patellar resurfacing, and in approximately up to 16% of patients with patellar resurfacing. The cause of patellofemoral pain after total knee arthroplasty is unknown but may at least be partly related to postoperative malalignment and anatomic variations resulting in high patellofemoral contact forces. Immunohistochemical studies on innervation of the anterior knee have found hyperinnervation in the peripatellar soft tissues. In theory, circumpatellar denervation using electrocautery could result in a lower prevalence of anterior knee pain. To date, no relevant clinical studies addressed the results of circumpatellar electrocautery denervation in total knee arthroplasty without patellar resurfacing. Primary objective was therefore to determine the effect of circumpatellar electrocautery denervation in total knee arthroplasty without patellar resurfacing, particularly with regard to anterior knee pain.
Study objective
The null hypothesis is that there is no difference in terms of pain and clinical outcome between total knee arthroplasty with and that without circumpatellar electrocautery denervation.
Study design
Preoperative, 12 months, 2 years and 4 years after total knee arthroplasty.
Intervention
Circumpatellar electrocautery denervation in total knee arthroplasty without patellar resurfacing.
