About this trial

The goal of this observational study is to evaluate the technique of subchondroplasty in patients with advanced knee osteoarthritis.

The main question it aims to answer is:

• Does the subchondroplasty technique with the administration of AccuFill Porous Bone Substitute Material (BSM) is effective in the relief of mechanical pain in patient with knee osteoarthritis ?

Participants will go under a minimally invasive surgery procedure (subchondroplasty) and fulfil 3 validated questionnaires to assess pain, functional impairments and subjective improvement.

This study will be conducted for 4 years.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patient 18 years of age or older;

Patient with a Body Mass Index ≤35 (BMI=kg/m2);

Patient with Kellgren-Lawrence grade 3-4 Osteoarthritis, as reviewed on MRI and plain radiography;

Patient with knee bone marrow lesions confirmed by MRI result at least 3 months before the intervention;

Disqualifiers

Patient with a Body Mass Index > 35 (BMI=kg/m2);

Patient with inflammatory rheumatic pathologies;

Patient with frontal deformities (varus, valgus) of more than 12°;

Patient with degenerative pathologies at the operative stage but likely to benefit from a conservative intervention (osteotomy), except if the knee is centred;

Trial population

Trial outcomes

Primary outcomes

1

Change from baseline (inclusion) in Patient-Reported Pain Scores on the Visual Analog Scale (VAS) to 3 months.

Visual Analog Scale (VAS) is a unidimensional measure of pain intensity, used to record patients' pain progression. It will helped the patient to assess the perceived mechanical knee pain on a horizontal, non-calibrated line of 10 cm, ranging from very low (0) to very high (10)

Time frame
Month 3

Secondary outcomes

1

Change from baseline (inclusion) in Patient-Reported Pain Scores on the Visual Analog Scale (VAS) to each visits

Visual Analog Scale (VAS) is a unidimensional measure of pain intensity, used to record patients' pain progression. It will helped the patient to assess the perceived mechanical knee pain on a horizontal, non-calibrated line of 10 cm, ranging from very low (0) to very high (10).

Time frame

2

Change from baseline (inclusion) in International Knee Documentation Committee (IKDC) score to each visits

IKDC is a subjective knee evaluation form to detect improvement or deterioration in symptoms, function and sports activities due to knee impairment. This self-questionnaire is divided into three parts (symptoms, sports activities, function) and gives a score between 0 (worst) and 100 (best).

Time frame
Week 3, Week 6, Month 3, Month 6, Month 12, Month 24, Month 36, Month 48
3

Change from baseline (inclusion) for the Knee injury and Osteoarthritis Outcome Score (KOOS) to each visits

KOOS is a knee-specific instrument, developed to assess the patient's opinion about their knee and associated problems. The KOOS evaluates both short-term and long-term consequences of knee injury. It contains 42 items divided into five subscales: KOOS Pain, KOOS Symptoms, Activities of Daily Living (KOOS ADL), Sport (KOOS Sport), and Quality of Life regarding the knee (KOOS QOL). Total scores can range from 0 to 100.
