This retrospective, controlled clinical study aims to evaluate the effectiveness of a targeted biological support injection containing a hyaluronic acid and amino acid combination in patients with chronic lateral epicondylitis (tennis elbow). Medical records will be reviewed to compare outcomes between patients treated in routine clinical practice with a 3-dose injection regimen (weeks 0, 2, and 4) plus a home exercise program and those treated with a home exercise program alone. Key outcome measures include pain intensity (VAS), functional status (PRTEE), grip strength, and pressure pain threshold.

Change in Pain Intensity (VAS)
Pain intensity will be measured using a 10-cm Visual Analog Scale (VAS).
Time frame: Baseline, Week 4, and Month 3
Change in Pressure Pain Threshold (Algometry)
Pressure pain threshold over the common extensor tendon will be measured using a handheld algometer.
Time frame: Baseline, Week 4, and Month 3
Change in Functional Status (PRTEE Score)
Functional disability and pain will be assessed using the Patient-Rated Tennis Elbow Evaluation (PRTEE).
Time frame: Baseline, Week 4, and Month 3
Change in Grip Strength (Hand Dynamometer)
Grip strength will be measured using a hand-held dynamometer. Measurements will be recorded in kilograms (kg). Higher values indicate greater strength.
Time frame: Baseline, Week 4, and Month 3
