Long-term Evaluation of Outcomes of Patients Undergoing Autologous Bone Marrow Concentrate Infiltration vs. Hyaluronic Acid for the Treatment of Bilateral Knee Osteoarthritis. Prospective Observational Study

This is a prospective observational study for long-term clinical evaluation (minimum 4-year follow-up) in patients treated within the research protocol "OA-bi-blind" (Double-blind randomized trial on the treatment of bilateral knee osteoarthritis: Autologous bone marrow concentrate VS. hyaluronic acid)

Detailed Description

60 patients treated within the "OA-bi-blind" research protocol from 2016 to 2019 at the II Orthopaedic and Trauma Clinic of the Rizzoli Orthopaedic Institute will be recruited. These are patients undergoing infiltration for the treatment of bilateral gonarthrosis of autologous bone marrow concentrate vs. hyaluronic acid within the OA-bi-Blind Research protocol.Prior to enrollment, patients will be contacted provided they have released their personal or legal guardian's e-mail address and/or personal or legal guardian's telephone number in advance and only after verifying the patient's consent to be contacted again for research purposes. If the patient is interested in participating in the study, arrangements will be made with him or her to send the Informed Consent and Disclosure Letter.

The patient will have to return (by means of a pre-stamped envelope that he will have received together with the consent itself) the Informed Consent completed in all its parts to the address given in the information letter. Only upon obtaining the fully completed Informed Consent may the investigator subject the patient to a telephone interview.

Alternatively, the patient may receive the Informed Consent and the questionnaire for clinical evaluations digitally.Clinical score data will be collected from the questionnaires conducted at long-term follow-up of patients enrolled in the study. The data collected during the long-term follow-up, will be used to evaluate the time course of outcomes after treatment with autologous bone marrow concentrate versus hyaluronic acid in patients who received either treatment as per the ''OA-bi-blind'' protocol.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Knee Injury and Osteoarthritis Outcome Score (IKDC)-Subjective Knee Evaluation Form
Time Frame: baseline
This is a subjective, knee-specific rating scale that is considered one of the most reliable assessment tools in the evaluation of knee pathology. The questionnaire examines 3 categories: symptoms, sports activity, and knee function. According to this questionnaire, a score between 0 and 100 can be obtained, where a high score is associated with a high level of function and minor pain symptoms. A score of 100 is in fact interpreted as a condition in which there are neither limitations in conducting activities of daily living nor symptoms.
baseline
Knee Injury and Osteoarthritis Outcome score- (KOOS Score)
Time Frame: baseline
The full questionnaire consists of five subscales and they cover: pain (9 items), symptoms (7 items of which two relate to stiffness), functions and activities of daily living (17 items) physical function, sports activities and leisure (5 items) and quality of life in relation to the knee (4 items). All items in the relevant subscales have the same response mode, use a 5-point Likert scale, and each question is assigned a score from 0 to 4, where 0 indicates "no difficulty" and 4 "a severe difficulty). Score range 0-100 for each subscale
baseline
EuroQol Visual Analogue Scale (EQ-VAS )
Time Frame: baseline
This is a visual analog scale that has a range of scores from 0 (worst imaginable health condition) to 100 (best imaginable health condition).
baseline
Tegner Score
Time Frame: baseline
This questionnaire allows the estimation of a subject's motor activity level with a score between 0 and 10, where 0 represents 'inability' and 10 represents 'participation in competitive sports, such as soccer at the national or international level. This score is the one most commonly used to define the motor activity level of patients with knee disorders. In the study, the Tegner Score will be filled in directly by the investigator, through an interview the patient. In addition, questions will also be asked about return to sports and pre-injury, pre-treatment and recovered/achieved sports level .
baseline
EQ-5D (EuroQoL) Current Health Assessment
Time Frame: baseline
EQ-5D is a standardized measure of health-related quality of life developed by the EuroQol Group to provide a simple generic questionnaire for use in clinical and economic evaluation and population health surveys
baseline
Patient Acceptable Symptom State (PASS)
Time Frame: baseline
A tool to assess patient satisfaction in consideration of their current degree of pain, function, and daily activity. Patients can express if their state of health will be satisfying, answering "yes" or "no.
baseline
Visual Analogue Scale (VAS)
Time Frame: baseline
Visual analog scale consisting of a straight line segment (10 cm length), the ends of which correspond to "no pain" (0) and "the strongest pain imaginable" (10).
baseline
Final treatment opinion
Time Frame: baseline
The patient should indicate satisfaction and relative degree with the treatment performed after a minimum of 4 years after infiltrative treatment. All patients will be able to indicate their health condition by choosing from this answers: much better", "somewhat better", "no change", "a little worse", "much worse".
baseline
Failure
Time Frame: baseline
The patient will be asked to indicate whether and when new infiltrative or surgical treatment was performed. Questions will also be asked about any complications and reinterventions
