Among the first of disease entities of which there are any historical records is the syndrome of arthritis. The terms hypertrophic arthritis and degenerative arthritis are considered analogous to the term osteoarthritis. There are various views regarding the aetiology of this condition. Key (1933) observed in a series of human cadveric knee joints that the lesions were usually on the weight bearing areas of the knee, and in majority the age was above 50. Harrison et al. (1953) observed that the earliest lesion of degenerative arthritis in man was found in the non-weight bearing areas of the joint, which were not subjected to the pumping action that occurred in the weight bearing areas. Bennet and Baur (1931) supported this view and stated that the nourishment and maintenance of normal cartilage was dependent upon adequate lubrication by the synovial fluid which in turn was best maintained by normal articular apposition and function: absence of which would lead to accelerated articular cartilage degeneration.
