      <study_design>Randomization: Randomized, Blinding: Triple blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: The randomization method will be simple and unit of randomization will be individual. Randomization will be done using www.randomization.com and using random numbers in sealed envelopes. Based on the random number in the envelope and its evenness and individuality, the patient will belong to the test and control group, Blinding description: According to the study design, it is not possible to blind the researcher and the clinical caregiver. Study participants are not aware of the size of bone particles and patients' information is not provided to the outcome assessor and data analyzer.</study_design>
