Joint regeneration in adults
There is clear evidence for spontaneous joint remodelling and repair in man. Following injury various joint structures, including ligament and tendon, go through a fairly classical cascade of acute injury with immobility, subsequent inflammatory responses and finally adaptive repair response [1]. Synovium also has considerable powers of regeneration given its reappearance following surgical synovectomy [2]. Adaptive responses at fracture sites, at regions of weight bearing and osteophytosis attest to the remodelling capabilities of bone [3]. Additionally, cartilage regeneration at sites of osteophytosis is well recognized and even hyaline articular cartilage-like tissue may occur following corrective osteotomies in OA [4] or following subchondral bone microfracture techniques [5].
A better understanding of the pathophysiological basis for these diverse joint remodelling responses could have major implications for future joint repair strategies. The classical paradigm of joint repair involves the concept of a mesenchymal
