Study summary

Background: Matrix-associated autologous chondrocyte implantation (MACI) has been recently used to treat cartilage defects. The investigators had previously developed a biphasic osteochondral composite as the construct for chondrocyte implantation. The investigators further conducted this feasibility study of such device to treat patients with osteochondral lesion of the knee joints.

Read the detailed description

Methods: Ten patients with symptomatic isolated osteochondritis at the femoral condyle were treated by replacing the pathological tissue with autologous chondrocyte-laden biphasic cylindrical plug of DL-poly-lactide-co-glycolide, with its lower body impregnated with -tricalcium phosphate as the osseous phase. The osteochondral lesion was drilled to fashion a pit of identical size and shape as the plug. The chondrocyte-laden plug was press-fit to fill the pit. Outcome of repair was examined by KOOS scale at 3, 6 and 12 months postoperatively, and tissue sample was collected with second-look arthroscopic needle-biopsy at 12 months. The primary outcome parameter was the postoperative change of KOOS; and the secondary outcome parameter was the regeneration of cancellous bone and hyaline cartilage at the repair site.

The record gives a start of Mar 2009, a primary completion of Dec 2011 and a completion of Dec 2011. It does not say whether these dates are actual or estimated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 22, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
