The objectives of this review are to evaluate the relative effects on pain and adverse effects of intra-articular morphine given for pain control after knee arthroscopy versus:

other routes of morphine administration.
We will also examine whether the analgesic effect of intra-articular morphine is dose-dependent by direct comparisons of different doses of morphine.
