BiPhasic Cartilage Repair Implant (BiCRI) IDE Clinical Trial - Taiwan
Taiwan92 participantsStarted 2011-10
Plain-language summary
The purpose of this trial is to evaluate the safety and effectiveness of the Biphasic Cartilage Repair Implant (BiCRI) compared to marrow stimulation in the treatment of chondral and osteochondral lesions located on the medial femoral condyle, lateral femoral condyle, or trochlea of the knee. The hypothesis is that the BiCRI provides an improvement in pain and function as compared to baseline, that is no worse than marrow stimulation at 1 year.

Inclusion criteria
. Male or female presenting with a single, symptomatic chondral or osteochondral lesion of the medial or lateral femoral condyles or the trochlea requiring primary surgical intervention
. Skeletally mature (epiphyses are confirmed to be closed on x-ray)
. Lesion size requires no more than 2 implants (assuming patient were to be randomized to the treatment group). Lesion size will be assessed at the time of the study procedure for all subjects. If the size of the lesion is appropriate for 1 or 2 implants the patient will be randomized. If the lesion is found to be too large the patient will not be included in the trial, but will be treated according to standard of care. Lesion sizes that are considered appropriate include the following:
. Willing and able to refrain from taking pain medications (including: narcotic and non-steroidal anti-inflammatory drugs) for 7 days prior to the baseline preoperative visit and for 7 days prior to the 12-month postoperative visit (i.e., a "wash out" period)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Willing and able to return for follow-up over a one year post-operative period
. Willing and able to comply with all postoperative guidelines
Exclusion criteria
. ≥ 55 years old
. Lesions \> grade II on the articular surface of the tibia or patella
. Kissing lesions (defined as an opposing lesion \> grade II on the surface of the tibia or patella). Lesion ≤ grade II on opposing surface would be acceptable.
. Prior surgical treatment of the lesion
. Lesion would require more than 2 implants (assuming patient were to be randomized to the treatment group). Lesion sizes that are not considered appropriate include the following:
. Lesion will require bone grafting
. Rheumatoid arthritis and other inflammatory arthritis
