Core tip: This paper discusses the current arthroscopic treatment options of cartilage injuries. Over 1 cm2 full thickness chondral lesions are seen in 4%-5% of patients under 40 years undergone arthroscopy. Conventional arthroscopic treatment may not have successful results although chondral defects are observed with such a high incidence. Addition of novel scaffolds to conventional methods will provide beneficial effects on healing of articular cartilage lesions with hyaline. We now formulate a new treatment algorithm with scaffolds under the light of existing literature. In future, we expect the widespread use of arthroscopic surgery in chondral defects.
