Brief Summary
SHARC is an observational study of cartilage patients who are treated with surgery that involves obtaining a harvest biopsy. SHARC will study the natural healing process of the harvest biopsy site based on histological and biochemical analyses of repair tissue biopsies, synovial fluid biomarkers, medical imaging (MRI) and gait analysis.

Eligibility Criteria
Patients undergoing surgery that involves the harvest of cartilage tissue as part of the treatment
You may qualify if:
- Being able to provide signed and dated informed consent form.
- Scheduled for one of the following surgical treatments
- Surgery that involves the harvest of cartilage tissue as part of the treatment, thus creating a fresh cartilage defect, which is then left to heal naturally. Examples of such surgery are autologous chondrocyte implantation (ACI) and mosaicplasty.
- Autologous stromal cell implantation (ASCI), as part of the ASCOT randomised clinical trial.
You may not qualify if:
- Inadequate understanding of verbal explanations or written information given in English, or having special communication needs.
- Chronic severe renal insufficiency
- Anything that would preclude the individual's full compliance with or completion of the study.

- After the study end and after the study results have been published
- Access Criteria
- The access will adhere to Keele University's Research Data Management Policy. Briefly, a data-sharing agreement must be issued and signed by appropriate authorities before data are released or analyses are performed on behalf of the requester. The Data-sharing agreement will prohibit any attempt to (a) identify study participants from the released data or otherwise breach confidentiality, (b) make unapproved contact with study participants.
After the study end and publication of results, individual data will be available upon request to the PI. No patient identifiable information will be shared. All individual data will be link-anonymized and a minimum of 3-way anonymization of relevant data will be used to ensure that participants cannot be identified from the supplied data.
