Health-related quality of life and direct costs in patients with anterior cruciate ligament injury: single-bundle versus double-bundle reconstruction in a low-demand cohort--a randomized trial with 2 years of follow-up.

Purpose To evaluate health-related quality of life (HRQL) in patients undergoing anterior cruciate ligament (ACL) reconstructive surgery by use of 2 procedures and to estimate the direct costs of surgery. Methods We performed a 2-year randomized, prospective intervention study of 2 surgical ACL reconstruction techniques (anatomic single bundle [SB]v double bundle [DB]). Fifty-five consecutive outpatients, with a mean age of 30.88 years, were randomized to SB or DB ACL reconstruction. The Medical Outcomes Study 36-item Short Form Health Survey (SF-36) was used to measure HRQL (primary outcome). ACL injuries were assessed by the International Knee Documentation Committee (IKDC) score (secondary outcome). The use of medical resources and their costs were evaluated. Results We included 52 patients in the final analyses (23 in the SB group and 29 in the DB group). At baseline, there were no significant differences in study variables. At 2 years of follow-up, there were no significant differences in SF-36 and IKDC scores between groups. However, compared with baseline, the SF-36 physical function, physical role, bodily pain, social function, and emotional role scores were significantly better in the SB group (P Conclusions HRQL and medical outcomes were similar between SB and DB ACL reconstruction techniques, 2 years after surgery. However, the SB technique was more cost-effective. Level of Evidence Level I, randomized controlled trial.</p

SAT0475 Locus of control of pain in patients with knee osteoarthritis

Knee osteoarthritis (OA) is a degenerative joint disease in which pain and disability tend to increase in parallel with the disease duration. As in other chronic diseases, pain togetherwith functional disability supposes not only a reduced quality of life but also the need for sufferers to adapt. The importance of the concept of locus of control, i.e. the belief in the possibility and/or ability to control symptoms and achieve and maintain a specific level of health, has been suggested in patients with chronic pain
