A longitudinal incision resembling a bucket-handle tear was made in the menisci of 8 rabbits, 6 dogs, 11 pigs and 12 sheep. In some of the animals of each species the cut was repaired by suturing, and in others it was not. Gross inspection, as well as examination by light and electron microscopy, showed that no healing had occurred after six months in the sutured or the unsutured wounds and that the meniscus was incapable of significant intrinsic repair. In a second experiment longitudinal, transverse and T-shaped cuts were made in the menisci of 12 sheep, and a flap of synovium was sutured into the wound. Three months later there was clear evidence of healing by the formation of cartilaginous tissue. Examination by light and electron microscopy showed that the newly formed repair tissue, possibly derived by metaplasia from the synovium, had a morphology intermediate between hyaline cartilage and fibrocartilage. Synovial implantation may therefore be considered as an alternative to meniscectomy in the management of the torn meniscus.

Fifty-four adults with eighty hips affected by congenital disease which had not been treated have been reviewed. Fifty-nine per cent of forty-two dislocated hips had fair or poor grading scores. The incidence of osteoarthritis was markedly increased in the presence of a well-developed false acetabulum. Unilateral dislocation led to valgus deformity and degenerative changes in the ipsilateral knee in seven of twenty-two patients. Dislocation did not increase the incidence of symptomatic lumbar spondylosis. The height of the dislocated head on the ilium was not found to be related to the prognosis for the hip, the knee or the lumbar spine and did not correlate with the development of the false acetabulum. Frank congenital subluxation eventually led to osteoarthritis of the hip.
