Brief summary

The infiltration of Platelet Rich Plasma (PRP) at the end of Temporomandibular Joint (TMJ) arthrocentesis is already an established procedure in the treatment of Temporomandibular Disorders (TMD). Arthrocentesis is a minimally invasive surgical procedure, which aims to eliminate the inflammatory mediators from the inside of the TMJ. PRP is an autologous concentrate of platelets and growth factors, derived from centrifugated blood. Several studies have described the benefits of PRP: it enhances wound healing because of the presence of cytokines and growth factors, and is also stimulates chondrocytes to biosynthesis of collagen. Ropivacaine is a local anesthetic that has been synthesized for use in infiltration anesthesia and to produce both peripheral and central block. Unlike one of its analogues, Bupivacaine, Ropivacaine anesthetize the sensory fibers without affecting the motor ones. The main goal of this investigation is to test the benefits of adding Ropivacaine to the infiltration of PRP in patients submitted to TMJ arthrocentesis.

Detailed description

To investigate the potential reduction of pain in the postoperative week in patients submitted to temporomandibular joint double portal arthrocentesis with lavage and Platelet Rich Plasma (PRP) the authors designed a double-blind randomized clinical trial, comparing a treatment group with additional ropivacaine and a control group without ropivacaine.

Interventions

DRUGRopivacaine injection

Ropivacaine is a local anesthetic that has been synthesized for use in infiltration anesthesia and to produce both peripheral and central block. Unlike one of its analogues, Bupivacaine, Ropivacaine anesthetize the sensory fibers without affecting the without affecting the motor ones. Ropivacaine comes as solution for injection.

Temporomandibular arthrocentesis is a minimally invasive surgical procedure, which aims to eliminate the inflammatory mediators from the inside of the TMJ.

DRUGPRP injection

Platelet-Rich Plasma (PRP) is an orthobiological adjuvant treatment. PRP has properties to restore intra-articular hyaluronic acid, increases glycosaminoglycan chondrocyte synthesis and balances joint angiogenesis. It is often used as a viscosupplement in TMJ arthrocentesis

Ringers lactate solution is used during arthrocentesis to wash out the joint inflammatory cells and to release the stuck disc phenomenon.

Masking description

The distribution of intervention is performed by attributing a code for each patient. Each code will have been previously distributed randomly between PRP + Ropicavaine and PRP only. The codes are kept closed singularly in an envelope. Before treatment, the nurse will ask the patient to choose an envelope. At this moment, the envelope is placed on a table, and the patient writes his name. Alone, the nurse opens the envelope and sees the code and the indication of PRP or PRP + Ropivacaine. Then, she will prepare, in her room, isolated from the whole team, one 3cc syringe with PRP or PRP + 1cc ropivacaine (7.5mg/ml), depending on the code. Once the code is attributed to the patient, she will deliver a tray with the prepared syringe for treatment. After finishing the arthrocentesis, the doctor injects the chosen treatment. Daily for one week, the patient answers a questionnaire, and at the end of the postoperative week, each patient will be blinded evaluated with a clinical examination.

Intervention model description

For this randomized clinical trial an appropriate number of sealed envelopes will be prepared: 15 for PRP and 15 for PRP + Ropivacaine. Patients with inclusion criteria will be seen in an orofacial pain session and assessed for pain using the VAS scale, by scoring the degree of pain between 0 (absence of pain) and 10 (maximum pain). Then the patients are proposed for TMJ arthrocentesis.
