About this trial

The goal of this clinical trial is to test whether adding a collagen protein scaffold can improve cartilage repair in elbow joint injuries, compared to standard surgery alone. The study will enroll 90 patients (aged 18-55) with elbow cartilage damage who haven't responded to conservative treatments.

The main questions it aims to answer are:

* Does the collagen scaffold help regenerate better-quality cartilage (measured by MRI scans at 3 and 6 months)? * Do patients experience better pain relief and elbow function after this combined treatment?

Researchers will compare two groups:

* Experimental group : Receives microfracture surgery + collagen scaffold implant * Active Comparator group : Receives microfracture surgery alone

Participants will:

* Undergo arthroscopic surgery (either procedure) * Complete follow-up visits at 1 week, 1 month, 3 months, and 6 months * Have MRI scans and functional assessments * Report pain levels and daily activity limitations through questionnaires
