Obesity may not diminish outcomes or increase risk of complications in total knee replacement patients

Obesity alone may not diminish outcomes or increase the risk of complications in total knee replacement (TKR) patients, according to two research studies presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). However, TKR replacement patients may face significantly longer hospital stays and related costs.

Prosthesis may not improve overall outcomes in female total knee replacement patients

Anatomic differences between male and female knees have resulted in the creation and regular use of gender-specific implants. However, a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) finds that a specialized prosthesis may not improve overall outcomes in female total knee replacement (TKR) patients.

Study finds no improvement of vitamin D levels in hip fracture patients who live in sunny climate

While it is well known that a majority of hip fracture patients of all ages and both sexes have insufficient or deficient levels of vitamin D, a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons looks at whether or not living in a warm, sunny climate improves patient vitamin D levels.

Study: Total knee replacements in younger patients with juvenile arthritis last for 10 years

When you think of knee replacement surgery, you generally envision an older adult with painful arthritis. But the procedure is also used for younger patients with juvenile idiopathic arthritis whose joints have been severely damaged by the disease. Because the surgery in younger patients is relatively rare, little data exist on the longevity of knee replacements in JIA patients.
