We wish to address the efficacy and safety of Platelet Rich Plasma (blood platelets), a new treatment for lateral epicondylitis (tennis elbow) and compare this new treatment to either injection with steroid or saline solution.

All injections are guided by ultrasonography.

Condition Intervention
Lateral Epicondylitis
Biological: Platelet Rich Plasma
Procedure: Isotonic Saline Solutions
Drug: Triamcinolonacetonid

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Treatment of Lateral Epicondylitis. Platelet Rich Plasma vs. Steroid vs. Saline Solution

Primary Outcome Measures:
  • Changes in pain as a continuous outcome measure. Using The Patient-Rated Tennis Elbow Evaluation (PRTEE) questionaire. [ Time Frame: first day, 1 months, 3 months, 6 months, 12 months. ]
    We use the PRTEE questionaire, which is validated for tennis elbow.

Secondary Outcome Measures:
  • Functional Disability [ Time Frame: First day, 1 month, 3 months, 6 months, 12 months ]
    We use the PRTEE questionaire, validated for tennis elbow.

  • Ultrasonographic changes [ Time Frame: first day, 1 months, 3 months, 6 months, 12 months ]
    We meassure ultrasonographic changes in: tendon thickness and doppler activity.

  • Adverse events [ Time Frame: through out the entire 12 months ]
    The number of adverse events leading to withdrawal

  • Pain induced by the treatment [ Time Frame: 1 months after treatment ]
    A numeric scale 0-10 adressing if the treatment caused any aditional pain, and the duration: <1 week, 1-2 week, 3-4 weeks, > 4 weeks.

Arms Assigned Interventions
Experimental: Platelet Rich Plasma Biological: Platelet Rich Plasma
27ml of autologous whole blood added to 3ml of ACD-A (Citrate Anticoagulant). After separation of the platelets, a high concentration of platelets (3-4ml Platelet Rich Plasma) is injected into the tendon through 7 perforations of the tendon, guided by ultrasound.
Other Names:
  • Plasma, Platelet Rich
  • PRP
  • Blood Platelets
Sham Comparator: Isotonoic Saline Solution Procedure: Isotonic Saline Solutions
3ml of Isotonic Saline Solution is injected into the tendon through 7 perforations of the tendon, guided by ultrasound.
Other Name: Physiological Saline Solution
Active Comparator: Steroid (Triamcinolonacetonid) Drug: Triamcinolonacetonid
Triamcinolonacetonid 40mg/ml. 40mg of Triamcinolonacetonid is mixed with 2ml of Lidocaine 10mg/ml. It is injected deep into the tendon, guided by ultrasound.
Other Name: Kenalog

Detailed Description:
Plate Rich Plasma (PRP) is a new treatment for tendinopathy. A high concentration of blood platelets is made from the patients own blod, and then injected into the tendon. The idea is that the complex mixture of growth factors within the platelets can stimulate the healing process of the tendon. We want to address the efficacy and safety of this new treatment and compare it to either the best documented treatment, Steroid injection, or to a saline solution. We want to make a randomized controlled trial with 60 participants, 20 in each of the 3 groups, and a 12 months follow up. All injections are guided by ultrasonography.
