The introduction of operative arthroscopy as a treatment option for a
wide spectrum of trauma and orthopaedic complaints in a small group of
in-patients has led to changes in operative procedures. With knee-joi
nt injuries, any operative procedure can be precisely planned and is o
ften carried out in two steps. Anterior displacement of the tibial tub
erosity and other repair procedures for cartilage lesions have now lar
gely given way to arthroscopic treatment. Arthroscopic diagnosis is su
perior in accuracy to clinical/apparative diagnosis and reveals many a
dditional findings that can also be treated immediately. In our group
of patients the high number of degenerative lesions often combined wit
h synovial disorders was striking.
