1.1 Osteoarthritis is a continuous and entirely physiologic adaptive process that occurs in every joint. These include the replication of cells that produce matrix, enzymes, protease inhibitors, cytokines, and other peptides. Along with the synthesis of new tissue there is a release of breakdown products into the synovial fluid. Enzymes and phagocytes are required to clear these breakdown products. Normal tissue turnover involves synthesis and breakdown in well-regulated balance. In the degenerative state this balance is upset producing inflammation-derived alterations to the synovium, cartilage, capsule, tendons, and bone. Common causes of such alterations include increased loading, physical stress, and traumatic injury to the joint.

1.2 The rationale for the use of corticosteroids in temporomandibular joint therapy is that they inhibit prostaglandin synthesis and decrease the activity of collagenase and other enzymes that degrade the articular cartilage. Platelet rich plasma is a novel therapeutic agent that has several potential advantages over corticosteroids for the treatment of degenerative pathology of the temporomandibular joint. Platelet rich plasma has been shown to have anti-inflammatory, analgesic, and anti-bacterial properties. It also restores intra-articular hyaluronic acid, increases glycosaminoglycan condrocyte synthesis, balances joint angiogenesis, and provides a scaffold for stem cell migration. Autologous platelet rich plasma injections for treatment of knee cartilage degenerative lesions and osteoarthritis have shown longer efficacy than hyaluronic acid injections in reducing pain and recovering articular function. Similarly, platelet rich plasma has shown to have better outcomes than corticosteroid injections in the management of lateral epicondylitis, and better outcomes than hyaluronic acid injections in the management of osteochondral lesions of the talus.

1.3 Current treatments for degeneration and osteoarthritis of the temporomandibular joint are focused primarily on palliation by reducing inflammation and inflammatory mediators. This study seeks to validate a therapeutic agent that has the potential to actively prevent the progression of degeneration in addition to reducing pain and inflammation

Further study details as provided by Kaiser Permanente:

Primary Outcome Measures:
  • Pain relief [ Time Frame: 24 weeks ]
    Changes in pain relief will be evaluated at 1, 3, and six month intervals using the Pain resource centers TMJ scale.

Secondary Outcome Measures:
  • Improvement in function [ Time Frame: 24 weeks ]
    The patients improvement in function will be evaluated at 1,3, and 6 months for improvement using the pain resource centers TMJ scale.

Enrollment: 0
Study Start Date: November 2013
Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Group A (corticosteroid injection group)
Group A will receive one intra-articular injection of 2 ml of solution containing 1ml of 10mg/ml Triamcinolone suspended in 1 ml of 0.5% Bupivacaine solution per affected joint
Drug: Group A (corticosteroid injection group)
Experimental: Group B (platelet rich plasma injection)
Group B will receive a 2 ml intra-articular injection of a platelet rich plasma preparation per affected joint
Biological: Group B (platelet rich plasma injection group)

Detailed Description:


2.1 The purpose of this study is to compare the efficacy, in terms of pain relief and improvement in function, of intra-articular injections with platelet rich plasma versus the current standard which is corticosteroid injections into the temporomandibular joint.


Ages Eligible for Study:   Child, Adult, Senior
