Abstract
Introduction
Autologous chondrocyte implantation (ACI) is expected to become applicable for middle-aged and elderly patients. Several techniques using suture anchor devices have been developed to fix artificial collagen membranes . However, no studies have investigated whether these suture devices affect clinical outcomes and MRI findings.
OBJECTIVE*
To compare postoperative outcomes and MRI findings in middle-aged and elderly patients who underwent ACI using the All Suture anchor (Jaguar knot suture anchor mini®︎) (AA group) and Knotless anchor (BC Push lock anchor®︎) (KA group).
Methods
A retrospective comparison was conducted on 18 knees (11 in the AA group and 7 in the KA group) that underwent ACI for traumatic knee cartilage injuries in patients aged 50 and older (average age of 58.8 years) between 2020 and 2023. Clinical scores (KOOS, IKDC, resting/motion VAS) before surgery and at 6 months postoperatively, as well as MOCART scores on MRI at 6 months postoperatively, were compared.
Results
Motion VAS in the KA group was significantly higher than that in the AA group(22.4±15.6 vs 56.6±27.9, p=0.018). MOCART scores in the KA group tended to be lower than that in the AA group (69.1±6.6 vs 57.1±24.8, p=0.25).
Conclusion
ACI fixed by all suture anchor devices can show a better clinical outcome. It might be caused by a smaller size of an anchor diameter than other devise not to effect to a cartilage surrounding graft in inserting an anchor.
