Nganvongpanit and colleagues investigated serum levels of hyaluronic acid HA and chondroitin sulfate CS for their correlation with tissue quality after cartilage repair with autologous chondrocytes versus subchondral drilling in a dog model. They reported better tissue quality in animals treated with chondrocyte implantation. Serum levels correlated with the histological score of biopsy samples CS showed a negative r and HA a positive r correlation. Many questions remain to be answered before serum markers can provide a reliable non-invasive tool to assess tissue quality but these data provide an important foundation for additional research. In the previous issue of Arthritis Research Therapy Nganvongpanit and colleagues 1 of Chiang Mai University in Thailand investigated the potential use of serum biomarkers such as hyaluronic acid HA and chondroitin sulfate CS to evaluate healing after cartilage repair procedures. They randomly assigned dogs to treatment with autologous chondrocyte implantation ACI versus subchondral drilling SD and followed the animals for 24 weeks post-operatively with .
