Background and study aims
Osteoarthritis is the most common form of arthritis, and the knee is one of the most commonly affected joints. Current treatment guidelines are focused on treatment of the symptoms but no progress has been made regarding the real mechanism of the disease. Carboplasty is a new technique that consists of applying the patient's own bone marrow aspirate directly to the union between the bone and the cartilage to delay the progression of the disease, repair the damage and hopefully regenerate the cartilage. The aim of this study is to evaluate the effectiveness and safety of this new technique by comparing it to a placebo (dummy treatment).

Who can participate?
Patients aged 30-80 years with knee osteoarthritis who have failed medical treatment and with evidence of bone lesions on MRI scans

What does the study involve?
The study involves symptom questionnaires and an MRI scan performed before the treatment. All patients are randomly allocated to either the placebo group or the carboplasty group. Once assigned to a specific treatment (without the patient knowing which treatment) patients undergo the procedure under sedation. After the treatment, all patients are followed up to 1 year after the procedure where the symptom questionnaires and the MRI scan are repeated. Throughout the follow-up, patients are constantly contacted to check for any adverse event to the procedure, and if present, they are treated.

What are the possible benefits and risks of participating?
Carboplasty is a new technique with promising results in previous studies. Probable risks related to the procedures are knee pain after the intervention, minor swelling of the knee, minor bleeding, complications from anesthesia, wound infections, and neurovascular lesions (problems that affect the blood vessels in the brain and spinal cord) during the procedures. However, these complications were minimized by having a clean and controlled environment in the operating room.

Where is the study run from?
Ruby Clinic Hall (India)

When is the study starting and how long is it expected to run for?
January 2013 to June 2017

Scientific titleCarboplasty for managing knee osteoarthritis: a placebo-controlled randomized trial
Study objectivesCarboplasty leads to better clinical and magnetic resonance imaging outcomes than placebo on patients with knee osteoarthritis (OA) and edema-like marrow signals.
Ethics approval(s)Approved 16/08/2014, Poona Medical Research Foundation Ethics Committee (Ruby Hall Clinic, 40 Sassoon Road, Pune, India 411001; +44 (0)20 66455582; reenew20@gmail.com), ref: VAD-01/RB/001
Health condition(s) or problem(s) studiedKnee osteoarthritis
InterventionPatients are randomized with a 1:1 ratio to either carboplasty or placebo. Allocation was performed by a research assistant blinded to the treatment using a computerized random number generator.

Both procedures are performed under sterile conditions, using IV sedation, and with fluoroscopic guidance. Patients in the placebo group have the PeCaBoo system inserted into the inferior and superior bone-cartilage interface (BCI) by itself, with no bone marrow aspirate being applied neither in the BCI nor intra-articular.

A reverse microfracture bio-enhanced with core decompression procedure is performed on the patients in the carboplasty group. 9 cc of tibial marrow aspirate is obtained from the proximal tibia using the PeCaBoo system in a syringe preloaded with 1 cc of heparin. Using the same syringe and the PeCaBoo system, 2 cc out of the 10 cc are injected into the superior BCI on the femoral condyle where the bone edema is detected on MRI. Another 2 cc is injected into the inferior BCI on the tibia ipsilateral to the femoral condyle. The remaining 6 cc is injected into the knee joint using the medial approach and a 22-gauge needle.

Patients are instructed not to exercise for 2 days after the intervention. After day 3, patients are allowed to use a stationary bike for 30 minutes every day followed by 15 minutes of cryotherapy. Complete return to activity is permitted after 1 month.
Intervention typeProcedure/Surgery
Primary outcome measureKnee pain evaluated by the visual analog scale of pain from 0 to 10 at baseline and 1 year after treatment
Secondary outcome measures1. Pain related to different activities measured using the Knee injury and Osteoarthritis Outcome Score (KOOS) from 0 (really symptomatic) to 100 (asymptomatic) at baseline and after 1-year post-treatment
2. Morphological evaluation and bone marrow edema measured using magnetic resonance imaging at baseline and after 1-year post-treatment
3. Adverse events measured using a questionnaire and self-reported monthly for 1-year post-treatment
4. Treatment failure, defined as total knee arthroplasty due to refractory pain despite the treatment, at 1-year post-treatment
