Detailed Description
Lateral epicondylitis and other chronic tendinopathies are now understood to be non-inflammatory conditions characterized by collagen degeneration, fibroblast proliferation, mucoid degeneration and neovascularization Biological-based treatments can trigger the release of cytokines and growth factors from platelets, leukocytes, macrophages and other inflammatory cells. These growth factors support neovascularization and the chemotaxis of fibroblasts and tenocytes. It stimulates proliferation and collagen remodeling of fibroblasts and tenocytes.
PrT involves multiple injections of a small amount of irritant or sclerosing solution. Common irritants include hypertonic dextrose, phenol-glycerin-glucose and sodium morrhuate. PrT injection mechanism is as follows; while hypertonic dextrose causes cell rupture through osmosis, monosodium morrhuate attracts inflammatory mediators and improves blood flow of the diseased tendon.Previous studies have shown benefit of PrT in the treatment of tendinopathies HA injection is a treatment method that increases the ability of sliding with its viscoelastic properties, reduces tendon surface friction and accelerates regeneration. In vitro models suggest that HA can increase collagen I production and accumulation with a dose-dependent positive collagen I / collagen III ratio. However, controlled randomised studies are still needed.
Mechanism of action of both PrT and HA is cell proliferation and the healing process of tendons, this study was conducted to compare the effect of PrT and HA in chronic lateral epicondylitis .

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Hyaluronic acid injection group
This is the study group in whom Hyaluronic acid injection was injected at lateral epicondylitis site.
|
Patients were infiltrated with injection single dose 30 mg/2 ml 1500 kilodalton high molecular weight hyaluronic acid at the lateral epicondyle according to the standard technique.
Other Names:
|
Active Comparator: Prolotherapy injection group
This is the control group in whom prolotherapy injection was given at lateral epicondyle site.
|
Patients were infiltrated with 5cc of dextrose 15% at the lateral epicondyle according to the standard technique.
For solution, 1 cc 2% lidocaine, 5 cc 30% hypertonic dextrose and 4 cc 0.9 % isotonic were used.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain via Visual Analogue Scale
Time Frame: Baseline, 6 week, 12 week
|
Change from baseline at 6 week and at 12 week Pain of the participants will be assessed by most widely used and accepted "visual analogue scale". It consists of a 10 centimeter line marked at one end with "no pain" and at other end with "worst pain ever". Participant is asked to indicate where on the line he or she rates the pain on the day of presentation, baseline, 6 and 12 weeks of follow-ups. Numerical score is given to it simply by measuring length between "no pain" to patients mark. |
Baseline, 6 week, 12 week
|
Quick - Disabilities of the Arm, Shoulder and Hand (QuickDASH)
Time Frame: Baseline, 6 week, 12 week
|
Change from baseline at 6 week and at 12 week The elbow disability scale was assessed using the Quick DASH (disability of arm, shoulder & hand) questionnaire containing 11 questions with five choices for each question. The final score can range between 0 (best condition) and 100 (worst condition). Participant is asked to answer the Quick DASH at baseline, 6 and 12 weeks of follow-ups |
Baseline, 6 week, 12 week

Grip strength via dynamometer
Time Frame: Baseline, 6 week, 12 week
|
Change from baseline at 6 week and at 12 week Pain-free grip strength is a commonly used objective measure of lateral epicondilitis-related disability with high reliability and validity. In the study, we used a hand dynamometer (Baseline® Hydraulic Hand Dynamometer 200 LB Standard). Patients were asked to sit, adduct the shoulder, flex the elbow to 90 degrees and put their forearm in a neutral position, then squeeze the dynamometer for three to five seconds. This test was conducted three times with 60-second intervals for each patient, and the mean patient grip strength was recorded at baseline, 6 and 12 weeks of follow-ups. |
