Abstract:
Purpose: Osteoarthritis and other joint disorders are the leading cause of disability in
the elderly and the treatment of joint lesions is challenging. Autologous chondrocyte implantation
(ACI) has been reported with variable effects for the treatment of osteochondral and other joint lesions.
In this study, we performed a meta-analysis of the recent literature to determine the clinical
applicability of ACI for osteochondral defects.
Methods: A meta-analysis was performed on the recent literature showing the effects of ACI on
osteochondral defects. The PUBMED, ScienceDirect and Google Scholar databases were used to
identify eligible studies from Jan 2010 to Sep 2022. Both fixed and random models of meta-analysis
were applied with all reported scoring systems to quantify the effectiveness of ACI on osteochondral
defects.
Results: The pool data of 965 patients as a case series after ACI from a fixed model showed a significant
improvement in the osteochondral defects (odds ratio = 8.75, 95%CI = 7.127 to 10.743, p
= 0.000). These results were further verified by a random model of meta-analysis. The data also
showed a substantial heterogeneity among the studies used in the meta-analysis (Q-value =
160.41, I-squared = 87.53, p = 0.000). Furthermore, this meta-analysis also compared different
ACI procedures with different scoring systems but the overall outcome remains the same as ACI
was found to be useful for the healing of the osteochondral defects.
Conclusion: This meta-analysis of 965 case series revealed that the ACI markedly improved the
damage osteochondral defects scores but the optimal treatment is still controversial, therefore further
studies are needed to validate these findings in a clinical setting.
