Overview
Brief Summary
Hip Osteoarthritis (HOA) is the most common joint disorder and a major cause of disability in the adult population. Thus, the early diagnosis, prevention, and treatment of the early stages of the disease and of the pre-arthritic condition, in particular in adolescents and young adults, is crucial to reducing the incidence of end-stage HOA and the need for total hip replacement (THR).
Evidence has mounted for a prominent etiologic role of femoroacetabular impingement (FAI) in the development of early HOA leading to the development of early cartilage and labral damage in the non-dysplastic hip. Therefore, the surgical treatment of FAI with mini-invasive arthroscopy is crucial. To improve the outcome after surgery, cortisone is routinely injected during the procedure for anti-inflammatory purposes.
The aim of the study is to compare the use of cortisone (gold-standard) (C) to a new class III medical device based on hydrolysed Collagen Peptides PEP-52, Peptys (P) and to investigate potential associations among the preoperative symptoms and hip function, the outcomes after arthroscopic surgery and biomarkers in synovial fluids (SFs).
Detailed Description
Patients scheduled for hip arthroscopy for treatment of FAI and/or labral pathology will be enrolled. The two treatments, C or P, will be administrated to patients with random sampling. SFs samples, when available, are obtained by aspiration just prior to surgical intervention, collected and stored for biomarkers analysis. At the baseline, OA severity will be assessed with a radiographic scoring system (Tönnis classification). Physical examination and clinical assessment using the Hip disability \& Osteoarthritis Outcome Score (HOOS) and VAS score for pain will be performed at the time of surgery and at 1-6 months of follow up. At the time of surgery, chondral (Outerbridge score) and labral pathology based on direct arthroscopic visualization will be also evaluated. The presence of inflammatory molecules at the baseline in the SFs will be also evaluated.

Exclusion Criteria
- •inability to provide informed consent;

Arms & Interventions
Cortisone (C)
To improve the outcome of the arthroscopy during the procedure, cortisone is injected for anti-inflammatory purposes at the end of the surgical procedure.
Intervention: Cortisone
Hydrolyzed Collagen Peptides
The use is alternative to cortisone
Intervention: Class III medical Hydrolyzed Collagen Peptides PEP-52 (Peptys)
Outcomes
Primary Outcomes
Hip disability & Osteoarthritis Outcome Score (HOOS) has five domains (pain, symptoms, activities of daily living, sports, recreational activities, quality of life): higher scores better hip function.
Time Frame: Pre-operative; 1 and 6 months post-operative
Investigate the preoperative symptoms and hip function
Visual Analogue Scale (VAS)
Time Frame: Pre-operative; 1 and 6 months post-operative
Investigate the preoperative hip pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain.
Osteoarthtitis severity assessed with radiographic scoring system (Tönnis classification)
Time Frame: Pre-operative; 1 and 6 months post-operative
Investigate the degenerative changes to the hip. The score consists of three progressive degrees: 0 no osteoarthritis; form 1 to 3 increasing the degeneration.
Secondary Outcomes
- Differences between the two study groups(6 months post-operative)
- Correlation between biomarkers in the pre-operative synovial fluid/urine and post-operative outcomes(Pre-operative; 1 and 6 months post-operative)
- Correlation between biomarkers in the pre-operative synovial fluid/urine and post-operative pain(Pre-operative; 1 and 6 months post-operative)
