Overview
Brief Summary
Osteoarthritis (OA) is one of the most common diseases resulting in large burdens on society.
Among the emerging treatments, Bone Marrow Concentrate (BMC) intra-articular injections are a promising regenerative approach. However, they offer only a temporary benefit since they target synovial and chondral tissues but fail to address the osteochondral interface, which plays a key role in the onset and progression of joint degeneration.
This project will investigate the efficacy of combined BMC injections, targeting both intra-articular tissues and subchondral bone, to treat OA in a Randomized Controlled Trial (RCT).
Detailed Description
The main aim is to evaluate in a RCT the potential of a new combined BMC treatment for OA, through the use of scores for the clinical outcome, the study of imaging and biological samples for tissue regeneration and systemic effects, and the identification of BMC and patient characteristics predictive of better results. All patients will undergo an arthroscopic procedure to debride degenerated tissues (this can offer a temporary benefit but not long lasting results) before BMC intra-articular injection. Half patients will receive also the injection of BMC at the subchondral level (bone samples obtained to allow BMC placement will be sent to the Lab). The same minimally invasive incisions will be used for all patients, ensuring patient blinding. Evaluations, performed by medical staff not involved in the treatment to ensure double blinding, will document subjective clinical improvement, functional measurements, biomarker study, and imaging with the use of modern 3TMRI and qCT technology. BMC characterization and patient features will be analysed to identify factors predictive of a better outcome.

Outcomes
Primary Outcomes
change of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score trend over time
Time Frame: basal 2,6,12 months after treatment
WOMAC is a validated score, designed to highlight the problems of patients with lower limb pathologies, in particular in terms of pain, stiffness and functionality. The score will be completed by the patient, possibly in the presence of an investigator, and simple guidelines for self-compilation will be provided.
Secondary Outcomes
- IKDC Subjective Knee Evaluation Form (IKDC)(2,6,12 months)
