About this study
Official title: Comparison of Autologous Osteoperiosteal and Osteochondral Transplantation for the Treatment of Medial Large Cystic Osteochondral Lesions of the Talus
Autologous osteoperiosteal transplantation using tissue harvested from the iliac crest is used to treat large cystic osteochondral lesions of the talus. This study is to compare clinical and radiological outcomes between patients undergoing AOPT and those undergoing AOCT for large cystic OLTs.
Read the detailed description
From March 2015 to March 2018, 23 patients who underwent AOPT and 23 patients who underwent AOCT to treat large cystic OLTs (>10mm) were retrospectively evaluated. For comparability, the two groups were matched based on their demographics, including sex, age, body mass index, side of injury, follow-up period, and the preoperative cyst volume. Clinical outcomes were assessed using the visual analog scale (VAS), the American Orthopaedic Foot \& Ankle Society (AOFAS) score, and the Tegner score. Donor-site morbidity was recorded according to the symptoms, including pain, stiffness, swelling and discomfort. Radiological outcomes were evaluated using the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score, and the International Cartilage Repair Society (ICRS) score was obtained during second-look surgery.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AOPTProcedure or surgery
The Osteochondral Autograft Transplant System (Arthrex) was used to create donor plugs. Osteoperiosteal grafts were harvested from the ipsilateral anterior superior iliac spine.
AOCTProcedure or surgery
Osteochondral grafts were harvested from the non-weight-bearing zone of the ipsilateral anterolateral distal femur.

Questions about this trial
What is this clinical trial studying?
An observational study of Osteochondral Lesions of the Talus, run by Peking University Third Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
MOCART (time frame: two years after sugery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jul 2021; AzTrials last refreshed its copy on 8 Nov 2026.
