Mid-Term Outcomes in HIV-Positive Patients After Primary Total Hip or Knee Arthroplasty.

J Arthroplasty. 2013 Jul 15;

Authors: Lin CA, Takemoto S, Kandemir U, Kuo AC

Abstract
We hypothesized that infection rates following total joint arthroplasty (TJA) in those with the human immunodeficiency virus (HIV) without hemophilia or drug use would be similar to rates in HIV-negative patients. Records at an urban HIV referral hospital were searched for patients who underwent primary total hip and knee arthroplasty from 2003 to 2010. The primary outcome was revision for infection. 372 HIV-negative and 22 HIV-positive TJA patients met inclusion criteria. The HIV-positive group had more deep infections than the HIV-negative group (9.1% v 2.2%, P=0.102). There were no infections in those with AIDS-defining CD4 counts. Those with HIV may have a higher risk of developing a deep infection. A low CD4 count is not an absolute contraindication to TJA in HIV positive patients.

Vitamin D Insufficiency in Patients With THA: Prevalence and Effects on Outcome.

Clin Orthop Relat Res. 2013 Jul 19;

Authors: Lavernia CJ, Villa JM, Iacobelli DA, Rossi MD

Abstract
BACKGROUND: The consequences of vitamin D insufficiency in the elderly remain controversial. The prevalence and potential effects of its chronic insufficiency on quality of life and physical function in patients undergoing THA have received little attention.
QUESTION/PURPOSES: We determined (1) prevalence of preoperative vitamin D insufficiency in patients undergoing THA and (2) relationships of insufficiency to patient-perceived outcomes (PPOs) and hip scores.

Leaded Eyeglasses Substantially Reduce Radiation Exposure of the Surgeon's Eyes During Acquisition of Typical Fluoroscopic Views of the Hip and Pelvis.

J Bone Joint Surg Am. 2013 Jul 17;95(14):1307-11

Authors: Burns S, Thornton R, Dauer LT, Quinn B, Miodownik D, Hak DJ

Abstract
BACKGROUND: Despite recommendations to do so, few orthopaedists wear leaded glasses when performing operative fluoroscopy. Radiation exposure to the ocular lens causes cataracts, and regulatory limits for maximum annual occupational exposure to the eye continue to be revised downward.
METHODS: Using anthropomorphic patient and surgeon phantoms, radiation dose at the surgeon phantom's lens was measured with and without leaded glasses during fluoroscopic acquisition of sixteen common pelvic and hip views. The magnitude of lens dose reduction from leaded glasses was calculated by dividing the unprotected dose by the dose measured behind leaded glasses.
RESULTS: On average, the use of leaded glasses reduced radiation to the surgeon phantom's eye by tenfold, a 90% reduction in dose. However, there was widespread variation in the amount of radiation that reached the phantom surgeon's eye among the various radiographic projections we studied. Without leaded glasses, the dose measured at the surgeon's lens varied more than 250-fold among these sixteen different views.

Continuing Clopidogrel During Elective Total Hip and Knee Arthroplasty: Assessment of Bleeding Risk and Adverse Outcomes.

J Arthroplasty. 2013 Jul 12;

Authors: Jacob AK, Hurley SP, Loughran SM, Wetsch TM, Trousdale RT

Abstract
Limited research assessing risks of continued clopidogrel perioperatively in patients undergoing elective orthopedic procedures exists. Patients that underwent elective primary or revision total knee arthroplasty (TKA) or total hip arthroplasty (THA) from 2007 to 2012 while taking clopidogrel at the time of surgical evaluation were retrospectively identified. Patient demographics, last dose of clopidogrel, intraoperative blood loss, blood transfusion, and presence of 30-day adverse cardiac events (ACE) were collected. Of 142 patients meeting criteria, 24 (16.9%) patients remained on clopidogrel perioperatively. Patients that continued clopidogrel were more likely to receive a blood transfusion within 24hours of surgery (31.8% vs. 7.7%; P=0.004) and during hospitalization (37.5% vs. 15.3%; P=0.02), but the incidence of 30-day ACE was not significantly different. Continuation of clopidogrel perioperatively for elective THA or TKA should be carefully considered.
