NCT02680392

Brief Summary

This randomized, double blind controlled trial is designed to investigate the potential benefits of radiofrequency in terms of analgesia and functional outcome, compared to the conventional continuous adductor canal block, for patients undergoing total knee arthroplasty for osteoarthritis.

Study Arms (2)

Pulsed and Continuous Radiofrequency

EXPERIMENTAL

In this group of patients undergoing total knee arthroplasty (allocation of patients is randomized), Pulsed radiofrequency (PRF) is applied to the saphenous nerve of the knee, associated to Continuous Radiofrequency (TRF) applied to the genicular nerves of the knee . A sham catheter is inserted in the mid-tigh to simulate a continuous adductor canal block, and connected to an infusion of normal saline (assessor and patient blinded to the treatment)

Procedure: Pulsed and Continuous Radiofrequency

Continuous adductor canal block

ACTIVE COMPARATOR

Continuous Adductor Canal Block Continuous adductor canal block is performed in this group of patients, with a catheter infusing ropivacaine 0.2% in the first 48 hours after surgery. The solutions bags are labelled in order to make assessor and patients, blinded to the treatment (Ropivacaine vs Normal Saline)

Drug: Continuous Adductor Canal Block

Interventions

Preoperative pulsed radiofrequency of the saphenous nerve and Continuous radiofrequency of the genicular nerves of the knee joint. The saphenous nerve will be approached at the adductor canal and it will be treated with Pulsed RF for 4 minutes at 42 Celsius degrees. Ropivacaine 0.5% 10ml with Dexamethasone 10mg will be injected after the RF. The Genicular terminal branches of the sciatic and femoral nerves will be treated with Continuous RF for 3 min at 80 Celsius degrees and then with 2 ml of Ropivacaine 0.5% and 10 mg of Methylprednisolone to each nerve (5 in total) A sham catheter in the mid-thigh will be placed for patients in the RF group, infusing Normal Saline 0.9% and simulating a Continuous Adductor Canal Block. To blind the investigator to the type of treatment for the postoperative assessment , every solution bag will be prepared by the Pharmacy of the Hospital, covered with a plastic envelope and labeled as "Study Solution".

Also known as: PRF
Pulsed and Continuous Radiofrequency

The patients in the Adductor canal group, will have a catheter for peripheral nerve block inserted under strict asepsis in the adductor canal under ultrasound guidance, and will receive for postoperative analgesia a 48-h continuous infusion of Ropivacaine 0.2% at 8 ml/hour The patients will receive, intraoperatively 10 mg of Dexamethasone i.v. To blind the investigator who will do the postoperative assessment to the type of treatment, every solution bag will be prepared by the Pharmacy of the Hospital, covered with a plastic envelope and labeled as "Study Solution". It will be always possible to crack the code and find out to which group the patient belongs
