An efficient calculational method for distorted wave impulse approximation analyses of quasifree knockout reactions is described. Since the usual Racah algebra is eliminated, it is straightforward to include spin-orbit distortions. Results are presented for 150 MeV ($p, 2p$) and ($p, \mathrm{pn}$) reactions. In some cases the effects of the spin-orbit terms are large.
