Patellar tendinopathy treated with PRP

Achilles tendinopathy treated with PRP

Plantar fasciosis treated with PRP

Chronic epycondylitis treated with PRP

A minimal description of the standard PRP preparation and administration protocol will be included to document clinical variability and enable comparative analyses. Across all participating centers, the following variables will be systematically recorded:

Type of PRP used (leukocyte-rich vs. leukocyte-poor), with standardized coding

Preparation method (single vs. double centrifugation), including specification of the device used

Injected volume

Anatomical site and administration technique (ultrasound-guided whenever feasible)

Number of treatment sessions and interval between sessions

Change in pain and functional limitation assessed using the Victorian Institute of Sport Assessment-Patella (VISA-P) questionnaire. Scores range from 0 to 100, with higher scores indicating better function and lower pain levels.

The VISA-A is an eight item questionnaire measures Achilles tendon pain and function, with scores ranging from 0 to 100 (higher scores indicating better function).

The Patient-Rated Tennis Elbow Evaluation (PRTEE) is a 15-item self-report questionnaire designed to measure pain and functional disability in patients with lateral epicondylitis (tennis elbow). It includes a 5-item pain subscale and a 10-item function subscale, providing a total score out of 100 to assess, evaluate, and monitor recovery.

The Foot Function Index (FFI) is a 23-item, self-administered questionnaire designed to measure the impact of foot pathology on function, assessing pain, disability, and activity limitation. It uses a 0-10 Likert scale for items within three subscales, with higher total percentages (0-100%) indicating greater, more severe pain and dysfunction.
