The Effect of Leukocyte Concentration on Platelet-Rich Plasma Injections for Knee Osteoarthritis: A Network Meta-Analysis.

Background: It is hypothesized that leukocyte-poor (LP) platelet-rich plasma (PRP) is preferred over leukocyte-rich (LR) PRP for the treatment of knee osteoarthritis (OA).

Methods: The MEDLINE, Embase, and Cochrane databases were reviewed for all English-language studies comparing LP-PRP or LR-PRP with relevant controls or each other. The follow-up periods were 6 months and 12 months.

Comparison of postoperative complications after total hip arthroplasty among patients receiving aspirin, enoxaparin, warfarin, and factor Xa inhibitors.

Optimal prophylaxis for prevention of venous thromboembolism (VTE) after total joint arthroplasty (TJA) remains debated. The purpose of this study was to compare postoperative complications in patients receiving different VTE chemoprophylactic regimens. Using a nationwide healthcare database, 72,670 THA patients without a history of VTE were identified.

Topical tranexamic acid reduces transfusion rates in simultaneous bilateral total knee arthroplasty: a retrospective case series.

Background: Topical tranexamic acid (TA) has been reported to be effective in reducing postoperative bleeding and transfusions after total knee arthroplasty (TKA). The main objective of this study was to retrospectively assess the effectiveness and safety of topical TA administration in patients undergoing simultaneous bilateral TKA.

Methods: We conducted a retrospective chart review of consecutive cohorts of patients undergoing simultaneous bilateral TKA.

Combined Volar Hamate Dislocation and Scapholunate Ligament Rupture: A Case Report.

Case: A twenty-two-year-old male patient presented to our trauma center after a motor-vehicle accident in which he sustained multiple injuries, including a volar dislocation of the hamate and ipsilateral scapholunate dissociation. Following closed reduction of the hamate dislocation, open reduction and stabilization of these carpal injuries was undertaken two days post-injury via a dorsal approach. Percutaneous Kirschner wires were used as well as two mini suture anchors to repair the scapholunate ligament.

Periprosthetic supracondylar femoral fractures following knee arthroplasty: a biomechanical comparison of four methods of fixation.

Purpose: The aim of this study was to determine the biomechanical properties of four fixation options for periprosthetic supracondylar femoral fractures.

Methods: Fourth-generation composite femurs were implanted with a posterior-stabilizing femoral component of total knee arthroplasty. All femurs were osteotomized to produce a AO/OTA 33-A3 fracture pattern and four different constructs were tested: (1) non-locking plate; (2) polyaxial locking plate; (3) intramedullary fibular strut allograft with polyaxial locking plate; (4) retrograde intramedullary nail.

Two-stage revision arthroplasty for management of chronic periprosthetic hip and knee infection: techniques, controversies, and outcomes.

In North America, two-stage revision arthroplasty is the treatment of choice for chronic periprosthetic infection of the hip and knee. Controversy exists regarding the diagnosis of persistent infection, cement spacer design, and duration of antibiotic therapy. Erythrocyte sedimentation rate and C-reactive protein tests have no clear cutoff values for detecting infection before reimplantation of hardware, and aspiration for microbial culture can yield false-negative results.

Topical tranexamic acid reduces transfusion rates in total hip and knee arthroplasty.

The efficaciousness of topical tranexamic acid use at the end of knee arthroplasty surgery to reduce blood loss and transfusion requirements has previously been shown. The aim of this study was to retrospectively assess the effectiveness of topical tranexamic acid use, comparing 155 patients undergoing hip and knee arthroplasty surgery in which tranexamic acid was routinely used, to a group of 149 patients from a similar time frame prior to the introduction of tranexamic acid use. The transfusion rate fell from 19.

Predicting the longer-term outcomes of total hip replacement.

Objective: The objective of this study was to identify the patient-level predictors (age, sex, body mass index, mental health, and comorbidity) for a sustained functional outcome at a minimum 1 year of followup after total hip replacement (THR).

Methods: We reviewed data from our registry on 636 consecutive patients from 1998 to 2005. Demographic data and the outcome scores of the Western Ontario McMaster University Osteoarthritis Index (WOMAC) and Medical Outcomes Study Short-form 36 (SF-36) scores were extracted from the database.

The relation between body mass index and waist-hip ratio in knee osteoarthritis.

Background: The best measure of body habitus as a risk factor for chronic disease is not well defined. Our intent was to examine the relation between waist-hip ratio (WHR) and body mass index (BMI) as a measurement of body habitus in patients with end-stage knee osteoarthritis (OA).

Methods: We reviewed the data of 200 consecutive patients in our registry undergoing knee replacement surgery for demographic data of age, sex, BMI and WHR.

PCL reconstruction with the tibial inlay technique following intra-medullary nail fixation of an ipsilateral tibial shaft fracture: a treatment algorithm.

Our case report highlights the complexity of treating multi-ligament knee injuries in the setting of ipsilateral long bone trauma. We describe the use of the tibial inlay technique for PCL reconstruction in the setting of a tibial shaft fracture treated with an intramedullary nail. We also present a comprehensive treatment algorithm for the treatment of ligamentous knee injuries in the setting of long bone trauma.

Predicting the longer term outcomes of total knee arthroplasty.

We asked the question of what are the patient level predictors (age, gender, body mass index, education, ethnicity, mental health, and comorbidity) for a sustained functional benefit at a minimum of 1 year follow-up after total knee arthroplasty(TKA). Five hundred fifty-one consecutive patients were reviewed from our joint registry between the years of 1998 and 2005. Baseline demographic data and the outcome scores of the Western Ontario McMaster University Osteoarthritis Index (WOMAC) and Medical Outcomes Short-Form 36 (SF36) scores were extracted from the database.

Surgical treatment of refractory tibial stress fractures in elite dancers: a case series.

Background: Treatment of tibial stress fractures in elite dancers is centered on rest and activity modification. Surgical intervention in refractory cases has important implications affecting the dancers' careers.

Hypothesis: Refractory tibial stress fractures in dancers can be treated successfully with drilling and bone grafting or intramedullary nailing.

Phaeohyphomycosis infection leading to flexor tendon rupture: a case report.

A rare previously unreported cause of flexor tendon rupture is described. A 66-year-old man presented with a fully extended left middle finger, accompanied by swelling and purulent drainage. Prior to presentation, he had received a steroid injection for left middle finger stenosing tenosynovitis and subsequently developed culture-proven phaeohyphomycosis fungal infection and secondary enterococcal bacterial infection, requiring pharmacotherapy and incision, drainage, and debridement for abscess formation.
