Stem cell intra-articular injection in Japan follows a sequence of assessment, cell collection, preparation, and injection into the target joint. Adipose tissue is the common source in private practice, taken under local anesthesia. Preparation happens away from the patient, so collection and injection are usually separate appointments.
The injection itself is performed in a clinical setting with sterile technique, and some clinics use ultrasound guidance to confirm placement. Ask whether guidance is used, since accuracy of placement is one of the factors that varies between providers offering otherwise similar treatments.
Regulatory framework affects documentation rather than technique. Ask which classification applies, what records you will receive, and whether they can be provided in English. For patients who will continue care elsewhere, documentation that a physician at home can actually read is more useful than a certificate that cannot be interpreted. Ask what the record includes about cell numbers and preparation method, as those details are the ones an outside physician will look for. Ask also whether imaging performed at the clinic can be exported in a standard format.
