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.

Treatment groups
Trial outcomes
Primary outcomes
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)
Secondary outcomes
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).
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).
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.
