Encouragingly at 1 year, second-look arthroscopy revealed no bone formation or bone exposure at the articular surface which was covered with smooth firm hyaline cartilage
. MRI at 1 and 5.5 years showed that the defect was filled, that there was smooth integration with the surrounding tissue, and that the repair was maintained over time.
Compared with normal cartilage cells, dedifferentiated chondrocytes are more likely to generate fibrous cartilage instead of hyaline cartilage
; the latter has better biomechanical properties and is more durable.
Thus, histology of the IGF-1-induced pellets exhibited more similarities to those of normal, hyaline cartilage
. Notably, there were no apparent increases in the presence of hypertrophic chondrocytes with large and round shapes in the IGF-1 transduced pellets as compared with the control pellets (Figure 3(b) upper lane).
The limited regeneration capacity of articular cartilage generally leads to formation of fibrocartilage-like scar tissue, which replaces the native hyaline cartilage
Osteoarthritis (OA) of the knee due to degenerative changes of the articular hyaline cartilage
along with subchondral sclerosis, osteophyte formation, and synovitis represents a clinical conundrum that, due to its increasing prevalence in aging societies, places increasing burden on societal, financial, personal, and medical levels .
Collagen type I is generally considered as an indicator of fibrosis or dedifferentiation of chondrocytes in monolayer, which is not desirable in hyaline cartilage
Second-look arthroscopy performed on the majority of patients in both groups confirmed articular cartilage regeneration, and histologic staining suggested the formation of hyaline cartilage
, both of which are consistent results with previous findings .

; elastic cartilage; fibro cartilage); tendon allograft (achilles tendon; tibialis; patellar tendon); meniscus allograft; dental allograft (free gingival graft; connective tissue graft; pedicle graft); collagen allograft; amniotic allograft.
, such as that found in the nose, microscopically consists of chondrocytes.
These codes reflect different prognoses; grade 1 tumours are distinguished from those of grades 2 and 3.3 Grade 1 chondrosarcomas were reclassified by the World Health Organization in 2013 as "atypical cartilaginous tumorus" (ACT/CS1).4 The tumours are moderately cellular, with an abundant matrix of hyaline cartilage
. They rarely metastasize; the 10-year survival rate is 83-95%.
During this process, careful preservation of hyaline cartilage
was ensured and bones were constantly revised to avoid their damage.
The tumor has a characteristic biphasic histology comprising sheets of primitive mesenchymal cells with interspersed islands of well-differentiated hyaline cartilage
. The tumor is diagnosed primarily on the basis of morphology because of a nonspecific immunoprofile and a general lack of availability of molecular diagnostics.
