The study by Gomez et al., "The Fate of Spacers in the Treatment of Periprosthetic Joint Infection," evaluates the clinical course and success rate of treatment of periprosthetic joint infection with two-stage revision with spacer placement in the interim period. The current review critically analyzes the findings of this study and examines how these findings may influence patient care in the field of hip and knee replacement. Gomez et al. report sobering results of two-stage revision with spacer placement for periprosthetic joint infection...

BACKGROUND: Although relatively rare, non-unions and mal-unions of tibial plateau fractures present significant challenges for the orthopedic surgeon. With careful pre-operative planning, tibial plateau mal-union or non-union revision surgery with intra-articular and varus opening osteotomies can provides good functional results when performed early (within 1 year) after primary surgical procedure. QUESTIONS/PURPOSES: We present our treatment algorithm for approaching and treating non-union or mal-union of tibial plateau fractures...

BACKGROUND: The role of platelet-rich plasma (PRP) in the treatment of sport-related injuries is unclear, largely due to the heterogeneity of clinical results. This may relate to compositional differences in PRP from different separation systems. QUESTIONS/PURPOSES: This study aims to compare the composition of PRP produced with five different commercially available systems, focusing on cellular concentrations and pH. METHODS: Seven donors (41 ± 12 years) provided blood for PRP preparation using five systems (Arthrex Angel, Emcyte Genesis CS, Arteriocyte Magellan, Harvest SmartPrep, and Biomet GPS III)...

BACKGROUND: Obesity is an established risk factor for complications after total knee arthroplasty (TKA) and is often associated with malnutrition. QUESTIONS/PURPOSES: 1. What is the prevalence of hypoalbuminemia in obese patients undergoing TKA? 2. What is the independent morbidity risk of malnutrition relative to obesity? METHODS: TKA cases were identified from the National Surgical Quality Improvement Program from 2005 to 2013. Propensity scores for having preoperative albumin measurements were calculated using demographics, BMI, and modified Charlson Comorbidity Index (CCI)...

BACKGROUND: Attaining stability during total knee arthroplasty (TKA) is essential for a successful outcome. Although traditional constrained total knee prostheses have generally been used in conjunction with intramedullary stems, some devices have been widely used without the use of stems, referred to as non-modular constrained condylar total knee arthroplasty (NMCCK). QUESTIONS/PURPOSES: The aim of this study was to compare revisions rates after total knee replacement with a non-modular constrained condylar total knee (NMCCK) compared to a posterior-stabilized (PS) design...

BACKGROUND: Trapeziometacarpal arthrodesis (TMA) has been complicated by nonunion and hardware failure. QUESTIONS/PURPOSES: We hypothesized that modification of the TMA technique with a locking cage plate construct would afford reliable bony union while producing greater hand function than trapeziectomy with ligament reconstruction and tendon interposition (LRTI) at early follow-up. METHODS: We enrolled 36 consecutive patients with trapeziometacapal osteoarthritis (14 TMA patients (15 thumbs), 22 LRTI patients (22 thumbs))...

The current generation of hip resurfacing consists of a metal-on-metal ball and monoblock socket of minimal thickness. Although results in certain patient subgroups have been excellent at up to 15 years of follow-up, other subgroups have had poor results. The hard-on-hard bearing is susceptible to edge-loading conditions and may produce excessive metallic debris; furthermore, other patients have had allergic reactions to the metal byproducts. In both situations, there can be clinical failures from adverse local tissue reactions...

BACKGROUND: The modular head taper junction has contributed to the success of total hip arthroplasty (THA) greatly. Taper corrosion and wear problems reported for large and extra-large metal-on-metal bearings as well as for bi-modular THA stems have cast doubt on the benefit of the taper interface. Presently, corrosion problems are being reported for nearly all kinds of artificial hip joints incorporating metal heads, questioning taper connections in general. QUESTIONS/PURPOSES: This study aimed to review the mechanical and electrochemical relationships that may lead to taper corrosion, which have been reported more commonly in recent literature, and to also review the contribution of patient characteristics and surgical techniques involved in taper assembly that may contribute to the problem...

BACKGROUND: Modularity in total hip arthroplasty has been used for decades with great success, but new findings regarding corrosion artifacts have caused a resurgence in tapered junction research. Mechanically assisted crevice corrosion (MACC) is thought to be the mechanism by which corrosive attack occurs. Myriad multi-factorial variables are known to influence the susceptibility of a modular taper junction to MACC. Some of these variables are design and manufacture related and others can be controlled by the surgeon...

BACKGROUND: Oxidized zirconium (OxZr) femoral component for total knee arthroplasty (TKA) have been introduced in an attempt to reduce polyethylene wear and secondary osteolysis and improve longevity of implants. QUESTIONS/PURPOSES: We reviewed clinical studies in literature evaluating OxZr femoral component for TKA. The aim of this review was to evaluate the clinical outcome and survival rate of TKA with an OxZr femoral component. METHODS: A review of the existing literature was undertaken to collect data on the OxZr femoral component in order to provide a better understanding of its performance...

BACKGROUND: Polyethylene (PE) wear is a major contributor to implant loosening following total knee arthroplasty (TKA), and advanced bearings in TKA are being investigated with hopes of reducing or eliminate wear-related loosening. Currently, information on knee tribology is available from national joint registries and may be the best tools to evaluate the efficacy and safety of design innovations in joint arthroplasty. QUESTIONS/PURPOSES: We performed a review of national joint registries trying to answer the following questions: "Which is the main factor directly related to revisions rate in TKA?" and "Are there new bearing options better than conventional ones?" METHODS: A review was performed of all published annual reports of National Joint Registers, as well as of the literature...

BACKGROUND: Precision medicine has been adopted in a range of clinical settings where omics data have led to greater characterisation of disease and stratification of patients into subcategories of phenotypes and pathologies. However, in orthopaedics, precision medicine lags behind other disciplines such as cancer. Joint registries have now amassed a huge body of data pertaining to implant performance which can be broken down into performance statistics for different material types in different cohorts of patients...

BACKGROUND: There is little data on whether preexisting allergies to implant materials and bone cement have an impact on the outcome of TKA. QUESTIONS/PURPOSES: This review article analyzes the current literature to evaluate the prevalence and importance of metal and cement allergies for patients undergoing total knee arthroplasty. METHODS: A review of the literature was performed using the following search criteria: "knee," "arthroplasty," and "allergy" as well as "knee," "arthroplasty," and "hypersensitivity...

Julien Girard
BACKGROUND: The hip resurfacing concept was developed for young and active patients, especially for femoral bone stock preservation. However, concerns about metal-on-metal bearings with adverse reactions to metal debris have led to a drop off in hip-resurfacing procedures. QUESTIONS/PURPOSES: The goal of this review is to evaluate our current knowledge of survivorship of second-generation hip resurfacing devices and elaborate international perspectives for product improvement...

BACKGROUND: The current role of metal-on-metal (MoM) bearings in hip arthroplasty remains controversial. The low wear offered by MoM bearings compared to metal-on-polyethylene and the possibility of a lower risk of dislocation with larger head sizes, encouraged a trend towards the re-introduction of the MoM bearing couple. However, recent evidence has shown that not all designs of the MoM bearing have been successful. QUESTIONS/PURPOSES: The purpose of this paper is to provide an update on the use of MoM bearings and address the following issues: (1) the reintroduction of metal-on-metal bearings in total hip arthroplasty, (2) the failure of metal-on-metal bearings in stemmed total hip arthroplasty, (3) the role of metal-on-metal hip resurfacing in modern orthopaedics and (4) metal-on-metal hip resurfacing versus total hip arthroplasty...
