Patient nutritional status was evaluated preoperatively using the serological parameters serum albumin, serum transferrin, and total lymphocyte count in 40 patients who underwent replacement arthroplasty (33 hips and 7 knees). Using the standard criteria, the overall incidence of malnutrition was 40% (16 cases). Ten percent (4 patients) had a negative value in the Rainey McDonald nutritional index. On follow-up, no patient had delayed wound healing or wound infection. Attention to surgeondependent factors can offset the high risk of delayed wound healing imposed by patient-dependent factors.
