Identifying the period of greatest blood loss after lower limb arthroplasty.

Arthroplast Today 2018 Dec 16;4(4):499-504. Epub 2018 Oct 16.

Primary Joint Outcomes Unit, Musgrave Park Hospital, Belfast, Northern Ireland.

Background: The use of tranexamic acid (TXA) in total hip replacement (THR) typically reduces blood loss by approximately 400 mL, and typical total blood loss is still approximately 1 L. A barrier to harnessing the full potential of TXA is disagreement on the optimum timing of administration. To address this, we aimed to identify the period of greatest blood loss. Read More

Confounding pain and function: the WOMAC's failure to accurately predict lower extremity function.

Arthroplast Today 2018 Dec 15;4(4):488-492. Epub 2018 Oct 15.

Department of Anesthesia and Pain Management, Toronto General Hospital, University Health Network, and Department of Anesthesia, University of Toronto, Toronto, ON, Canada.

Background: Investigations have revealed the Western Ontario and McMaster Universities Osteoarthritis Index's (WOMAC) inability to provide distinct assessments of pain and function. The Lower Extremity Functional Scale (LEFS) has not displayed this deficiency. Our purposes were to investigate further the WOMAC physical function's (WOMAC-PF) ability to accurately assess lower extremity mobility in patients undergoing total knee arthroplasty (TKA) and to establish a relationship between pre- and post-TKA WOMAC-PF and LEFS scores that accounts for the apparent bias WOMAC pain scores impose on WOMAC-PF scores.

Timed Up and Go test is predictive of Patient-Reported Outcomes Measurement Information System physical function in patients awaiting total knee arthroplasty.

Arthroplast Today 2018 Dec 1;4(4):505-509. Epub 2018 Sep 1.

Department of Orthopaedics, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.

Background: The Patient Reported Outcomes Measurement Information System (PROMIS) Computerized Adaptive Test (CAT) physical function rapidly assesses self-reported function capability. The Timed Up and Go (TUG) test is often used in clinical practice, but administration may be impeded by space and patient limitations. PROMIS CAT can potentially address these limitations, but we lack evidence if TUG and health indicators are predictors of PROMIS CAT. Read More

A risk-stratification algorithm to reduce superficial surgical site complications in primary hip and knee arthroplasty.

Arthroplast Today 2018 Dec 15;4(4):493-498. Epub 2018 Oct 15.

Department of Orthopedic Surgery, Columbia University Medical Center New York, NY, USA.

Background: Surgical site complications (SSCs) are the most common cause for readmission after total joint arthroplasty (TJA), increasing costs while predisposing to inferior long-term outcomes. Prophylactic use of closed-incision negative pressure therapy (ciNPT) may lower the risk of these complications, especially in high-risk populations, but appropriate-use guidelines are lacking for patients undergoing primary TJA. We sought to develop a risk-stratification algorithm to guide use of ciNPT dressings and test its use in normalizing the rate of superficial SSCs among high-risk groups. Read More

Division of Adult Reconstructive Surgery, NYU Langone Orthopedics, NYU Langone Health, New York, NY, USA.

Vascular complications in revision total hip arthroplasty may occur in cases where the components of the hip implant migrate through the acetabular wall, through the iliopectineal line of the pelvis, and into the pelvic cavity. This migration may lead to substantial intrapelvic vascular compromise, drastically increasing the surgical complexity and potential risk for morbidity and mortality in these surgical cases. Here, we present a case of a 78-year-old woman with significant acetabular protrusio, which resulted in intraoperative compromise of the external iliac artery with rapid extravasation. Read More

The effect of a preoperative education class on the rate of manipulation under anesthesia after total knee arthroplasty in a veterans population.

Arthroplast Today 2018 Sep 1;4(3):359-362. Epub 2018 Aug 1.

Department of Orthopaedics and Rehabilitation, Yale School of Medicine, New Haven, CT, USA.

Background: Arthrofibrosis after total knee arthroplasty (TKA) is a common complication, potentially occurring in up to 25% of patients, and may be treated during the early recovery period by manipulation under anesthesia (MUA). The majority of preoperative factors that predispose patients to postoperative stiffness are patient specific and not modifiable. The United States Veteran Affairs is a particularly challenging group given a higher baseline rate of medical comorbidities and opioid dependence than the general population. Read More

Acetabular wedge augments for uncontained tibial plateau defects in revision total knee arthroplasty.

Arthroplast Today 2018 Sep 30;4(3):313-318. Epub 2018 Apr 30.

Department of Orthopaedic Surgery, Washington University School of Medicine, St. Louis, MO, USA.

Tibial bone loss is a common scenario encountered during revision total knee arthroplasty. Reconstructive options depend on the amount and location of bone loss, but few good solutions exist to address large, uncontained tibial defects where cortical support is lost in the metadiaphyseal region. We describe a novel technique using acetabular augments to buttress a revision tibial component and recreate a hemiplateau during tibial revision total knee arthroplasty. Read More

Shoelace capsular and external rotators closure techniques in posterior (southern) approach to hip joint.

Arthroplast Today 2018 Sep 8;4(3):310-312. Epub 2017 Dec 8.

Department of Orthopaedic Surgery and Sports Medicine, Wakamatsu Hospital for the University of Occupational and Environmental Health, Fukuoka, Japan.

The possible increased risk of dislocation with a posterior approach for femoral hemiarthroplasty is attributed to disruption of the posterior soft-tissue structures, including the posterior capsular ligament structure and short external rotators of the hip. In this surgical technical note, we demonstrate the surgical technique for shoelace suturing of the external rotators and the capsule with use of ULTRATAPE. After prosthesis stem insertion, shoelace suturing using ULTRATAPE was performed between the great trochanter and the external rotators for preventing the external rotators from tearing. Read More

What can the surgeon do to reduce the risk of junction breakage in modular revision stems?

Authors:
Bernd Fink

Arthroplast Today 2018 Sep 31;4(3):306-309. Epub 2018 Aug 31.

Department of Joint Replacement, General and Rheumatic Orthopaedics, Orthopaedic Clinic Markgröningen gGmbH, Markgröningen, Germany.

Modular revision stems are very common in hip arthroplasty, but junction fracture remains a known failure mechanism. A review of the literature with description of cases with junction breakage of modular revision stems showed that in all 24 analyzed cases, there was a common finding: the combination of an effective osteointegration of the distal component and missing medial bone support of the proximal component. The result was a bending stress point of the stem construction in the region of the junction. Read More

Superior rim fracture of a vitamin E-infused highly cross-linked polyethylene (HXLPE) liner leading to total hip arthroplasty revision.

Arthroplast Today 2018 Sep 21;4(3):287-290. Epub 2018 Mar 21.

Michigan Orthopaedic Center, Lansing, MI, USA.

This case report looks at the failure of a vitamin E-infused highly cross-linked polyethylene acetabular liner that fractured at the superior rim of the locking mechanism. This calls to question whether there is a problem with the vitamin E-infused product or a flaw in the design of the liner or possibly a combination of the 2. Although there has been discussion of a possible minimum rim polyethylene thickness, there has not been a minimum thickness established. Read More

Total hip arthroplasty and femoral nail lengthening for hip dysplasia and limb-length discrepancy.

Arthroplast Today 2018 Sep 3;4(3):279-286. Epub 2018 May 3.

Departments of Surgery and Pediatric Surgery, McGill University, Montreal, Quebec, Canada.

The application of distraction osteogenesis through the use of magnet-operated, remote-controlled intramedullary lengthening continues to provide new opportunities for accurate limb equalization. While limb-length discrepancy and deformity can be addressed by total hip arthroplasty alone, the magnitude of correction is limited by the soft-tissue envelope and complications such as sciatic nerve palsy. This 3-patient case series presents the combination of staged ipsilateral total hip arthroplasty and retrograde intramedullary femoral nail lengthening for the correction of both deformity and limb-length discrepancy.
