Brief Summary:

Unicompartmental knee osteoarthritis (OA) is a common finding especially in patients with lower limb malalignment and previous meniscectomy. Among the various treatment options, in recent years there has been an increasing attention towards the use of biologic agents, such as platelet rich plasma and mesenchymal stem cells, as intra-articular injective approaches to relieve pain and restore joint function. Anyway, the sole intra-articular administration of these agents may not lead to satisfactory outcome in a relevant percentage of patients. In fact, unicompartmental osteoarthritis is not only characterized by degeneration of the articular cartilage, but also by pathologic changes in the subchondral bone, both at the tibial plateaux and in the femoral condyle. Magnetic resonance imaging reveals, in many cases, alterations of the subchondral tissue known as "bone marrow edema", which is a sign of bone overload and play a significant role in the progression of unicompartmental OA and is responsible of OA-related symptoms. Therefore, concurrent treatment of both the subchondral bone damage and intra-articular degeneration could led to better outcome for patients affected by unicompartmental OA: the aim of the present pilot trial is to assess the safety and describe the clinical outcome following concurrent intra-articular and subchondral bone application of Bone Marrow Concentrate (BMC). BMC is an autologous product rich in mesenchymal stem cells, which have immuno-modulatory and throfic properties and are able to restore the joint homeostasis by reducing the inflammatory distress traditionally associated to OA.

BMC will be collected directly in the operating room from the anterior iliac crest or the tibia by using the MARROW CELLUTION kit (Geistlich, Switzerland), which allows to obtain BMC without the need of centrifugation processes. Approximately 9-10 ml of BMC will be harvested: 6 ml will be injected, under fluoroscopic guidance, in the tibial emiplateaux (approx 3 ml) and in the femoral condyle (approx 3 ml) presenting MRI evidence of bone marrow edema. The remaining amount of BMC will be administered intra-articularly to address articular tissues (cartilage, menisci and synovium). Twenty-five patients affected by unicompartmental knee OA will be included in the present pilot trial and treated in a "Day-Surgery" regimen. They will be followed up at 3, 6, and 12 months' after treatment by clinical questionnaires and radiographic evaluations (x-rays at 6 and 12 months, MRI at 12 months' f-up). Any intra-op and post-op adverse events will be documented.

Primary Outcome Measures :
  1. Change in IKDC (International Knee Documentation Committee) subjective score [ Time Frame: baseline vs 12 months' follow-up ]
    IKDC subjective score is a validated clinical questionnaire (available also in Italian) designed to assess the functional status of the knee by a series of 10 items. The IKDC subjective score assess the overall function of the knee as subjectively evaluated by the patient who needs to answer a series of questions concerning symptoms and his/her activity level. It ranges from 0 to 100 points, with higher values representing a better knee status.


Secondary Outcome Measures :
  1. Variation in KOOS (Knee Injury and Osteoarthritis Outcome) Score [ Time Frame: baseline vs 12 months' follow-up ]
    KOOS score is a validated clinical questionnaire (available also in Italian) designed to assess the functional status of the knee by a series of 42 items. KOOS score consists of five sub-scales (Pain, Symptoms, Activity of Daily life, Sport, Quality of Life). The total score is obtained by summing the score of each sub-scale (max 21 point for Pain, 17 points for Symptoms, 41 points for Activity of daily life, 12 points for Sport, 9 points for Quality of Life). The total score's range is 0-100 and higher values represents better knee status.

  2. VAS (Visual Analogue Scale) for pain [ Time Frame: baseline vs 12 months' after treatment ]
    Visual Analogue Scale to evaluate average knee pain during daily life. Range is from 0 to 100 and higher values represent higher pain perceived by the patient.

  3. MRI (Magnetic Resonance Imaging) Changes in subchondral bone edema and cartilage status from basal to 12 months' follow-up [ Time Frame: baseline vs 12 months' follow-up ]
    MRI of the index knee will be performed to assess if the bone marrow concentrate was able to produce any effect on the subchondral bone edema and/or articular cartilage. To this purpose, the WORMS (Whole Organ Magnetic Resonance Imaging Score) will be adopted. This score allows to evaluate: 1) the amount of bone marrow edema (0-3 scale based on the extension of the bone marrow edema in the anatomical region considered, with higher value representing bigger bone marrow edema); 2) the cartilage damage (0 to 6 scale with higher values representing worse cartilage status)
