Firefighters Have a Higher Incidence of Trochlear Chondral Lesions than the Normal Population.

Background: Firefighters' knees are subjected to significant dynamic and static forces, resulting in increased knee complaints and a higher relative risk of osteoarthrosis, compared with aged-matched office workers. Firefighters wear or carry a total of 80 to 100 lbs. of gear while performing intensive physical activity.

Two-bundle posterior cruciate ligament reconstruction. An in vitro analysis of graft placement and tension.

This study had two purposes: first, to determine how femoral attachment location affects the load sharing between the two bundles of a Y-type posterior cruciate ligament reconstruction, and second, to determine how the bundles, separately and in combination, control posterior tibial translation throughout the full range of knee flexion. One and two-bundle reconstructions were performed in 12 cadaveric knees. The one-bundle reconstructions were attached within the femoral posterior cruciate ligament footprint at one of three locations, high and shallow (S1), mid and shallow (S2), or mid and deep (D).

Long-term follow-up of Chiari pelvic osteotomy in myelomeningocele.

The management of hip instability in myelomeningocele patients is controversial. The purpose of this study is to review our long-term results of isolated Chiari osteotomies in the treatment of hip instability in children with myelomeningocele. Between 1975 and 1988, 11 patients underwent 13 Chiari osteotomies for reducible hip subluxation or dislocation and acetabular deficiency.

Meta-analysis of surgical outcome in adolescent idiopathic scoliosis. A 35-year English literature review of 11,000 patients.

Study Design: Meta-analysis of the English literature on the surgical treatment of adolescent idiopathic scoliosis.

Objective: To gather comparable data from a number of different sources and combine the data to create a larger, more statistically significant pool of information for the analysis of surgical outcome.

Summary Of Background Data: Meta-analysis is a technique of scientific literature review used in outcome evaluation of medical treatment.
