PURPOSE: Arthroscopy of the hip joint is considered a demanding procedure with long learning curve. There are only a few studies that concentrate on this topic. This prospective clinical study evaluates the learning curve of the hip arthroscopy based on clinical outcomes, surgical time, and complication rate. MATERIALS: In this study, we first evaluated 150 hip arthroscopy procedures performed by a single surgeon. The patient group consisted of 86 females and 64 males with mean age 37 years (range 16-69)...

PURPOSE: Injection drug users are at high risk for both infection with blood-borne pathogens, namely, human immune deficiency virus (HIV), hepatitis-B, -C virus, various bacterial infections, as well as early primary and secondary joint degeneration. When total knee arthroplasty (TKA) is anticipated the risk of septic complications is a major concern. The purpose of this study was to assess the clinical and radiographic outcome of patients with a history of intravenous drug use after total knee arthroplasty...

Lukas Ernstbrunner, Mohamed A Imam, Octavian Andronic, Tabea Perz, Karl Wieser, Sandro F Fucentese
PURPOSE: Currently, individual studies lack the power to successively illustrate different failure modes; therefore, we undertook a systematic review to examine lateral unicompartmental knee replacement (lat UKR) failure modes. Furthermore, we compared early with midterm and late failures and fixed-bearing with mobile-bearing implants. METHODS: A search using the databases of PubMed, EMBASE, Cochrane, and annual registries was performed to search for failed lat UKRs...

BACKGROUND: Pubic bone nonunion and delayed union are reported as post-operative complications after peri-acetabular osteotomy (PAO). However, few studies have determined the incidence of delayed union using computed tomography (CT) scans. This study aimed to determine the incidence of delayed union at one year after PAO using X-ray and CT scans. METHODS: We performed a retrospective review of 150 hips in 132 consecutive patients with acetabular dysplasia who underwent PAO between January 2012 and June 2016 and evaluated 107 hips for which pelvic CT scans taken at one year after PAO were available...

PURPOSE: We investigated the various impingement angles (including both bony and prosthetic impingement) and impingement types that can occur after THA, even when the same combined anteversion parameter is used. We also investigated the relationship between impingement angle and acetabular morphology or femoral anteversion. METHODS: We evaluated 83 patients with no hip arthritis. We divided them into six groups according to acetabular CE angle (≤15°, >15-≤25°, and >25°) and femoral anteversion (≤20° and >20°)...

PURPOSE: Osteoporotic hip fractures are increasing in prevalence with the growing elderly population. Morbidity and mortality remain high following osteoporotic hip fractures despite advances in medical and surgical treatments. The associated costs and medical burdens are increased with a re-admission following hip fracture treatment. This study sought to identify demographic and clinical values that may be a predictive model for 30-day re-admission risk following operative management of an isolated hip fracture...

PURPOSE: The purpose of this study was to evaluate the outcomes of total hip arthroplasty (THA) revision with cementless stems using a numeric global radiological score (GRxS) that summarizes two previously validated scores: secondary bone stock (SBS) and osseointegration-secondary stability (O-SS). METHOD: One hundred fifty cases of THA were evaluated at a mean follow-up of 6.5 ± 3.7 years. The GRxS combines the SBS, which evaluated cortical bone thickness, bone density and bone defects in each Gruen zone and the O-SS, which evaluated the location and extent of a single radiolucent line...

PURPOSE: The fracture stage of non-traumatic osteonecrosis (ON stage 3) of the femoral head (ONFH) has an unfavourable prognosis frequently requiring total hip replacement (THR). The percentage could be lowered after core decompression. In earlier non-fracture ON stages, implantation of autologous bone marrow aspirate concentrate (BMAC) improved the effect of core decompression. The purpose was to evaluate the effect of BMAC in addition to core decompression in stage 3 ONFH. METHODS: A double blind RCT was conducted comparing two groups: core decompression plus saline injection or core decompression plus BMAC implantation...

#11
REVIEW
Tristan E McMillan, Alan J Johnstone
The surgical treatment of proximal humerus fractures remains controversial primarily due to the high complication rate associated with the available fixation methods. In an attempt to reduce the incidence of serious complications and subsequent poor clinical outcomes, proximal humerus locking plates have become popular but even these implants cannot overcome the risk of complications, especially those associated with loss of fracture reduction and screw cut-out/migration through the humeral head. In an attempt to address these issues, we have reviewed the literature, investigating the most likely causes for these predominantly mechanical complications and propose technical solutions...

OBJECTIVES: The influence of chondromalacia patellae (CMP) on post-operative anterior knee pain (AKP) following total knee arthroplasty (TKA) remains controversial, and few studies have focused on the relationship between them. The purpose of this study was to determine whether different CMP grades affect the incidence of AKP after TKA without patellar resurfacing. METHODS: We performed a retrospective analysis of prospectively collected data on 290 TKAs with the use of the low contact stress mobile-bearing prosthesis, without patellar resurfacing in 290 patients from February 2009 to January 2013...

PURPOSE: Whilst much is known on the multiple variables associated with a poor prognosis in soft tissue sarcomas, little evidence exists on the impact of fungation at the time of presentation. The aim of this study was to assess the impact of fungation on overall and disease free survival in soft tissue sarcomas. METHODS: The study comprised a retrospective review of all patients presenting with a soft tissue sarcoma between 1996 and 2014 managed at a single institution...

PURPOSE: National registries are valuable tools for understanding the results of shoulder arthroplasty across populations. These databases provide an unselected view of shoulder joint replacement within geographical areas that cannot be obtained from case series or prospective studies. They can be particularly helpful in determining which diagnoses, patients, procedures, and prostheses have higher than expected rates of revision. In an attempt to determine the generalizability of registry data, we asked, 'how similar are the patients and procedures among the different national registries?' METHODS: We analyzed national shoulder arthroplasty registries and databases accessed via Internet portals and through a PubMed literature search...

PURPOSE: Several therapeutic strategies have been used for managing unicameral bone cyst (UBC) of the proximal femur. However, there is insufficient evidence to support one treatment over another, and the optimal treatment is controversial. This study aims at describing our experience with surgical reconstruction of paediatric UBCs of the proximal femur using a proximal locking plate and fibular strut allograft. METHODS: In total, 14 consecutive paediatric patients with Dormans types IB (four cases) and IIB (10 cases) UBC were assessed...

REVIEW
Jun Yuan, Yufei Yan, Jiong Zhang, Bibo Wang, Jianmin Feng
BACKGROUND: Alpha-defensin, a novel biomarker, has shown great potential for the accurate diagnosis of periprosthetic joint infection (PJI) in recent years: many published studies have presented encouraging results. Nevertheless, the diagnostic accuracy of alpha-defensin is inconsistent across published studies. Moreover, the optimum value of the diagnostic threshold urgently needs to be ascertained. This meta-analysis sought to estimate the precision of alpha-defensin for the diagnosis of PJI and, where possible, to confirm the threshold...
