2. radial tunnel syndrome

3. carpal tunnel syndrome

4. septic or gouty arthritis

5. cervical radiculopathy

6. trauma to the affected elbow within the past 6 weeks

7. neuromuscular or musculoskeletal deficiency, which limits the ability to perform functional measurement (e.g. grip strength test)

7. Subject currently has an acute infection at the injection site

8. Subject has tested positive or been treated for a malignancy in the past or is suspected of having a malignancy or are currently undergoing radio- or chemotherapy treatment for a malignancy anywhere in the body, whether adjacent to or distant from the proposed rhPDGF-BB Injection treatment site

9. Subject is physically or mentally compromised (e.g. currently being treated for a psychiatric disorder, senile dementia, Alzheimer's disease, etc.) to the extent that the Investigator judges the subject to be unable or unlikely to remain compliant

10. Subject has an allergy to yeast-derived products

11. Subject has received an investigational therapy or approved therapy for investigational use within 30 days of injection procedure or during the follow-up phase of this study

12. Subject is a prisoner, or is known or suspected to be transient

13. Subject's condition represents a worker's compensation case

14. Subject is currently involved in a health-related litigation procedure

15. Subject has documented evidence of a history (e.g. liver testing) of drug/alcohol abuse within the 12 months prior to screening for study entry

16. Subject is pregnant, or able to become pregnant but not practicing a medically-accepted form of birth control, and/or intending to become pregnant during this study period

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Elbow Pain Assessments (VAS), Treated Subjects	Subjects were asked to report current pain level at the fusion site on a 100 mm Visual Analog Scale (with 0 being no pain and 100 being worst pain imaginable).	Baseline, 2, 4, 8, 12, and 24 weeks
Primary	Disabilities of the Arm, Shoulder and Hand (DASH), Treated Subjects	The disabilities of the arm, shoulder and hand (DASH) questionnaire is a self-administered region-specific outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The DASH consists mainly of a 30-item disability/symptom scale, scored 0 (no disability) to 100.	Baseline, 4, 8, 12, and 24 weeks
Primary	Total Score Patient Rated Tennis Elbow Evaluation (PRTEE), All Treated Subjects	The Pain and disability measured by the Patient Rated Tennis Elbow Evaluation (PRTEE) is a 15-item questionnaire designed to measure forearm pain and disability in patients with lateral epicondylitis (also known as "tennis elbow"). The PRTEE allows patients to rate their levels of tennis elbow pain and disability from 0 to 10, and consists of 2 subscales: PAIN subscale (0 = no pain, 10 = worst imaginable); -Pain - 5 items; FUNCTION subscale (0 = no difficulty, 10 = unable to do); Specific activities - 6 items; Usual activities - 4 items; In addition to the individual subscale scores, a total score can be computed on a scale of 100 (0 = no disability), where pain and functional problems are weighted equally	Baseline, 4, 8, 12, and 24 weeks
Primary	Grip Strength Test, All Treated Subjects	Grip strength testing will be performed to evaluate changes in the strength and sincerity of effort as a result of treatment for lateral epicondylitis. Testing will be performed to assess the pain-free grip strength (performing the test until discomfort is felt) and maximum grip strength (performing the test to the maximum of their ability). The test will be performed while the patient is standing with the elbow in full extension, as this position has been used to assess grip strength in patients with lateral epicondylitis. A Jamar Plus+ Digital Hand Dynamometer with the grip in the second position will be used because the second position has been assumed to be the most reliable and consistent position. Patients will be asked to perform three repetitions of each test (pain-free and maximum) at each study interval and the mean score will be calculated and used for analysis.	Baseline, 4, 8, 12, and 24 weeks
Primary	Maximum Grip Strength, Treated Subjects	A higher grip strength score indicates an improvement. A positive change from baseline indicates an improvement. Grip strength testing will be performed to evaluate changes in the strength and sincerity of effort as a result of treatment for lateral epicondylitis. Testing will be performed to assess the pain-free grip strength (performing the test until discomfort is felt) and maximum grip strength (performing the test to the maximum of their ability). The test will be performed while the patient is standing with the elbow in full extension, as this position has been used to assess grip strength in patients with lateral epicondylitis. A Jamar Plus+ Digital Hand Dynamometer with the grip in the second position will be used because the second position has been assumed to be the most reliable and consistent position. Patients will be asked to perform three repetitions of each test (pain-free and maximum) at each study interval and the mean score will be calculated and used for analysis.	Baseline, 4, 8, 12, and 24 weeks
