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
