Total Hip Arthroplasty Performed in Patients with Residual Poliomyelitis: Does it Work?

Byung-Ho Yoon MD, Young-Kyun Lee MD, Jeong Joon Yoo MD, PhD, Hee Joong Kim MD, Kyung-Hoi Koo MD

Patients with residual poliomyelitis can have advanced degenerative arthritis of the hip in the paralytic limb or the nonparalytic contralateral limb. Although THA is a treatment option for some of these patients, there are few studies regarding THA in this patient population.

High Complication Rate in Revision Total Hip Arthroplasty in Juvenile Idiopathic Arthritis

Stuart B. Goodman MD, PhD, Katherine Hwang MS, Susanna Imrie PT, MS

Revision total hip arthroplasty (THA) in patients with juvenile idiopathic arthritis (JIA) is challenging as a result of the patient’s young age, systemic disease, multiple affected joints, small proportions, and bone loss. The intermediate- to long-term results of these surgeries remain unknown.

Obesity Increases Length of Stay and Direct Medical Costs in Total Hip Arthroplasty

Hilal Maradit Kremers MD, MSc, Sue L. Visscher PhD, Walter K. Kremers PhD, James M. Naessens PhD, David G. Lewallen MD

The number of obese patients undergoing THA is increasing. Previous studies have shown that obesity is associated with an increased likelihood of complications after THA, but there is little information regarding the impact of obesity on medical resource use and direct medical costs in THA.

Cemented versus Uncemented Hemiarthroplasty for Displaced Femoral Neck Fractures: 5-year Followup of a Randomized Trial

Ellen Langslet MD, Frede Frihagen MD, PhD, Vidar Opland MD, Jan Erik Madsen MD, PhD, Lars Nordsletten MD, PhD, Wender Figved MD, PhD

Displaced femoral neck fractures usually are treated with hemiarthroplasty. However, the degree to which the design of the implant used (cemented or uncemented) affects the outcome is not known and may be therapeutically important.

High Metal Ion Levels After Use of the ASR™ Device Correlate With Development of Pseudotumors and T Cell Activation

Nils P. Hailer Dr, Med, Mats Bengtsson PhD, Christina Lundberg MD, Jan Milbrink PhD

Pseudotumors and immunologic alterations are reported in patients with elevated metal ion levels after resurfacing arthroplasty of the hip. A direct association of increased cobalt and chromium concentrations with the development of pseudotumors has not been established.

Single- or Two-stage Revision for Infected Total Hip Arthroplasty? A Systematic Review of the Literature

Hugh A. C. Leonard MA, BMBCh, Alexander D. Liddle BSc, MRCS, Órlaith Burke PhD, David W. Murray MD, FRCS(Orth), Hemant Pandit FRCS(Orth), DPhil

The best approach for surgical treatment of an infected THA remains controversial. Two-stage revision is believed to result in lower reinfection rates but may result in significant functional impairment. Some authors now suggest that single-stage revision may provide comparable results in terms of infection eradication while providing superior functional outcomes.

Association of Obesity With Inflammation and Pain After Total Hip Arthroplasty

Roja Motaghedi MD, James J. Bae MSc, Stavros G. Memtsoudis MD, PhD, David H. Kim MD, Jonathan C. Beathe MD, Leonardo Paroli MD, PhD, Jacques T. YaDeau MD, PhD, Michael A. Gordon MD, Daniel B. Maalouf MD, MPH, Yi Lin MD, PhD, Yan Ma PhD, Susanna Cunningham-Rundles PhD, Spencer S. Liu MD

The prevalence of obesity is increasing, and obesity often leads to degenerative joint disease requiring total hip arthroplasty (THA). Obesity is a proinflammatory state associated with an increase in chronic, low-grade inflammatory response. As such, it may augment the postoperative inflammatory response, which has been associated with postoperative pain and complications.

Surgical Hip Dislocation for Treatment of Femoroacetabular Impingement: Factors Predicting 5-year Survivorship

Simon D. Steppacher MD, Carmen Huemmer MD, MSC, Joseph M. Schwab MD, Moritz Tannast MD, Klaus A. Siebenrock MD

Patients with femoroacetabular impingement (FAI) often develop pain, impaired function, and progression of osteoarthritis (OA); this is commonly treated using surgical hip dislocation, femoral neck and acetabular rim osteoplasty, and labral reattachment. However, results with these approaches, in particular risk factors for OA progression and conversion to THA, have varied.

Comparison of Robotic-assisted and Conventional Acetabular Cup Placement in THA: A Matched-pair Controlled Study

Benjamin G. Domb MD, Youssef F. El Bitar MD, Adam Y. Sadik BS, Christine E. Stake MA, Itamar B. Botser MD

Improper acetabular component orientation in THA has been associated with increased dislocation rates, component impingement, bearing surface wear, and a greater likelihood of revision. Therefore, any reasonable steps to improve acetabular component orientation should be considered and explored.

Randomized Trial of Hemiarthroplasty versus Internal Fixation for Femoral Neck Fractures: No Differences at 6 Years

Ragnhild Øydna Støen MD, Cathrine M. Lofthus MD, PhD, Lars Nordsletten MD, PhD, Jan Erik Madsen MD, PhD, Frede Frihagen MD, PhD

Hemiarthroplasty has been shown superior to internal fixation for displaced femoral neck fractures (FNF) in the first 2 years. However, there are unanswered questions about the performance of hemiarthroplasty over the longer term compared with internal fixation.
