A femoral nerve catheter (FNC) is often used to minimize pain following total knee arthroplasty (TKA), but complications including inpatient falls, may increase as a result, despite fall prevention protocols. We evaluated the rate of falls in 707 primary TKAs performed with an FNC at a major academic center from May 2009 to September 2012. ⋯ At a rate of 2.7%, postoperative fall is one of the most common complications of TKA at our institution. While pain control may be good with the use of FNCs following primary TKA, improvements in fall prevention strategies or the use of alternative postoperative pain control modalities may need to be considered.

Head-neck adapters in total hip arthroplasty (THA) promise the reconstruction of optimal femoral offset and leg length in revision THA while retaining stable implants. Radiological parameters after adapter implantation in THA revision were determined in 37 cases. Significant reduction of leg length discrepancy and improvement of femoral offset (P < 0.001) were found. ⋯ Clinical scores were rather poor (median Harris hip score 54, WOMAC score 41) due to age and comorbidities, postoperative dislocation occurred in 3 cases. Only one stable femoral stem had to be revised due to recurrent postoperative dislocation. In conclusion, a head-neck adapter can be a valuable tool in certain cases of revision THA with acceptable dislocation rates while allowing the retention of stable implants.

The Patient Protection and Affordable Care Act (PPACA) is expected to increase health care availability through Medicaid expansion. The objective of this study was to evaluate potential effects of the PPACA by examining access to total hip arthroplasty in Southern California. 39 orthopaedic surgeons were called to schedule a hip arthroplasty. ⋯ This study showed that in Southern California, patients with income-based insurances are limited in the number of surgeons from whom they can receive care. Thus, although the PPACA will increase the number of insured patients, it may not similarly increase access to providers.

An effort to prevent PJI has led to the development of antimicrobial dressings that support wound healing. We sought to determine whether Aquacel Surgical dressing independently reduces the rate of acute PJI following TJA. ⋯ Multivariate analysis revealed that use of Aquacel dressing was an independent risk factor for reduction of PJI (odds ratio of 0.165, 95% confidence interval: 0.051-0.533). Aquacel Surgical dressing significantly reduces the incidence of acute PJI.

Lower extremity osteoarthritis with concomitant low-back pain (LBP) may obscure a clinician's ability to properly evaluate the status of hip or knee osteoarthritis and subsequent total joint arthroplasty (TJA) candidacy. A prospective cohort study was conducted to determine prevalence and severity of preoperative LBP among TJA patients, and the effect of TJA on alleviating LBP. ⋯ Compared to knees, hips also saw significant ODI improvement from preoperative to one-year postoperative. TJA candidates with considerable preoperative LBP should be counselled that TJA outcome may be impaired by the coexistence of spine disease, and that residual spine pain may continue following otherwise successful TJA.
