Comparison of Minced Cartilage Implantation Versus Microfracture for Acetabular Chondral Lesions Due to FAI (Femoro-acetabular Impingement) (CARTIFRAC)
A femoroacetabular impingement (FAI) is an abnormal contact between pelvis and the neck of femur. It occurs particularly when patient bends his hip and causes damage to the cartilage. In the long term, FAI can lead to the development of osteoarthritis (cartilage destruction) and may require a total hip replacement (THR).
Surgery to treat cartilage damage in the hip aims to maintain joint function and delay the onset of osteoarthritis. Microfracture remains the most commonly used treatment for cartilage lesions. It is a surgical technique for repairing articular cartilage that works by creating tiny fractures in the bone, which in turn stimulate the growth of new cartilage.
Cartilage autografting is a promising alternative to microfracture, offering good results in the knee joint. Cartilage autografting involves the use of autologous cartilage tissue (taken from patient body), which is harvested, ground up and reimplanted in a single surgical procedure to promote the growth of new cartilage and repair.
The published literature lacks large-scale studies comparing autologous cartilage transplantation with traditional joint-preserving surgeries, such as microfracture. This is the reason why this study is set up.

Descrizione dettagliata
Patients with femoro-acetabular impingement (FAI) often develop acetabular chondral lesions, which can impair joint function and reduce quality of life. If left untreated, chondral lesions can progress to osteoarthritis and thus require total hip arthroplasty.
Joint preservation surgeries for the treatment of hip chondral lesions, aim to maintain joint function and delay the onset of osteoarthritis. Microfracture remains the most commonly used treatment for chondral lesions.
Although microfracture is the reference surgical treatment for acetabular chondral lesions, several clinical studies and systematic reviews have reported higher rates of conversion to THA and lower patient-reported outcomes for microfracture compared to other techniques. Furthermore, microfracture can weaken subchondral bone and increase the formation of subchondral cysts, which may explain its inferior outcomes.
Minced cartilage implantation (MCI) has emerged as a promising alternative to microfracture, providing good outcomes in the knee joint. MCI involves the use of autologous cartilage tissue, which is harvested, minced, and re-implanted in a one-stage surgery to promote chondrogenesis and repair. Only one published study has reported on outcomes of MCI in the hip joint, showing good results for 11 male patients with FAI at 2 years follow-up. Therefore, the published literature lacks large-cohort studies that compare MCI to traditional joint preservation surgeries, such as microfracture.
This is the reason why this Clinical Study is set up. The hypothesis is that MCI will provide better short- to mid-term outcomes than microfracture in patients with acetabular chondral lesions due to FAI.

|---|---|
|
Sperimentale: MCI group
MCI involves the use of autologous cartilage tissue, which is harvested, minced, and re-implanted in a one-stage surgery to promote chondrogenesis and repair
|
Autologous minced cartilage will be harvested from the defect site and cam deformity area using a non-aggressive shaver blade .
The cartilage will then be collected and augmented with platelet-rich plasma from the patient's blood.
The platelet-rich plasma will be 100% autologous.
Cautious debridement of the chondral lesion up to the stable chondral margins will be performed, followed by removal of the calcified subchondral bone layer, then the minced cartilage will be implanted on the acetabular chondral lesion using an application cannula.

International Hip Outcome Tool-12 (iHOT-12)
Lasso di tempo: One year
|
The iHOT-12 is a validated self-administered questionnaire that measures health-related quality of life and changes after hip preserving treatments, in young active patients with hip disorders [13].
The questionnaire comprises 12 items, covering four domains: (i) symptoms and functional limitations, (ii) sport and recreational activities, (iii) job-related concerns, and [14] social, emotional, and lifestyle concerns.
Each item is scored using a visual analog scale (VAS) from 0 to 100, with a score of 100 being the best function and least amount of symptoms.
The final iHOT score is calculated as the overall mean of all 12 items, ranging from 0 to 100
