Details and patient eligibility

About

Based on the previous successful experiences, the investigators like to extend our patient population. In this study, the investigators aim to determine the safety and effectiveness of the Biphasic Cartilage Repair Implant (BiCRI) in the treatment of chondral and osteochondral lesions of the knee, including but not limited to more than one (1) lesion and the lesion that had been treated with microfracture or mosaicplasty but failed.

Full description

Patients who qualify for this trial and who are interested in participating will be consented using an Institutional Review Board (IRB) approved Informed Consent. Once a patient has signed the Informed Consent Form he/she is considered enrolled in the trial. If during surgery the size of lesion is found to meet exclusion criteria, the subject will be considered withdrawn (screen failure) from the trial.

Clinical trial eligibility should be determined by confirmation that the patient meets the criteria included in the Protocol. Standard arthroscopic technique should be used to fully assess the joint and determine if the chondral or osteochondral defect is appropriate for inclusion in the study. Through arthroscopic examination after initial debridement, the investigator should use his best judgment to estimate the size of the lesion, and the number of BiCRI to be applied.

Plain radiographs and MRI prior to 6-month (inclusive) visit will be performed according to routine clinical practice; however, 12-month and 24-monthpostoperative images should be done for study outcome evaluation

Enrollment: 11 patients

Sex: All

Ages: 16 to 65 years old
