The Current Status of Cell-Based Therapies for Primary Knee Osteoarthritis.

There is a growing interest in cell therapy for knee osteoarthritis. This study systematically reviews the current status of cell-based therapies. The authors review treatment modalities, clinical outcomes, and the economics of cell therapy.

Stem Cells and Platelet-rich Plasma for Knee Osteoarthritis: Prevalence and Cost in South Florida.

Introduction: The use of stem cell therapy (SCT) and platelet-rich plasma (PRP) injection for knee osteoarthritis (OA) is extremely controversial and at best experimental stage. These treatments are being offered across the nation for "cash-only payments." Our objectives were to determine (1) what proportion of board-certified orthopedic surgeons in Miami-Dade County offer SCT or PRP and (2) how much do practices charge for these services.

Primary Total Knee Arthroplasty: How Does Residual Patellar Thickness Affect Patient-Oriented Outcomes?

Background: Maintenance of the native patellar thickness has been deemed important for proper clinical outcomes after total knee arthroplasty (TKA). Our objective was to study the effects of the change in patellar thickness on patient-perceived outcomes (PPOs) after TKA. We hypothesized that reestablishing native patellar thickness after TKA results in better PPOs.

Preoperative Glycemic Control on Total Joint Arthroplasty Patient-Perceived Outcomes and Hospital Costs.

Background: The purpose of this study was to determine the influence of preoperative glycemic control in diabetic patients undergoing a primary total hip or knee arthroplasty. We wanted to study patient-perceived outcomes in the medium term, the length of stay, hospital costs, and rate of short-term postoperative complications.

Methods: One hundred twenty consecutive primary total joint arthroplasties (TJAs) performed in type 2 diabetic patients were stratified into 2 groups representing optimal and suboptimal preoperative glycemic control, based on serum levels of glycated hemoglobin (HbA), and those groups compared.

Total Joint Arthroplasty: A Granular Analysis of Outcomes in the Economically Disadvantaged Patient.

Background: Poor patients experience more serious complications and worse outcomes after surgery than higher-income patients. Our objective was to study detailed patient sociodemographic characteristics and preoperative/postoperative patient-oriented outcomes in economically disadvantaged and non-economically disadvantaged primary total joint arthroplasty patients.

Methods: From a consecutive series, 213 economically disadvantaged patients and 1940 non-economically-disadvantaged patients were statistically analyzed.

Access to arthroplasty in South Florida.

Our objective was to compare the availability of hip and knee arthroplasty to an adult insured by Medicaid and by private insurance. All orthopedic surgeons' offices in a South Florida county were contacted by telephone and presented with a hypothetical patient that needed either a hip or a knee arthroplasty for end stage arthritis. Two scenarios were presented.

Mental health and outcomes in primary total joint arthroplasty.

A consecutive series of 640 total joint arthroplasty patients was interviewed before surgery and at a minimum of 2 years following surgery. Statistical analyses were conducted to examine the effect of psychological distress and other patient characteristics on outcomes (Western Ontario and McMaster Universities Osteoarthritis Index, Short Form 36, and Quality of Well-Being index). Before and after surgery, distressed subjects had significantly lower scores than nondistressed subjects for most dependent measures (P range, .

Ethnic and racial factors influencing well-being, perceived pain, and physical function after primary total joint arthroplasty.

Background: Studies suggest, even when controlling for disease severity, socioeconomic status, education, and access to care, racial and ethnic minorities receive lower-quality health care and have worse perceived pain and function before and after total joint arthroplasty.

Question/purposes: We evaluated the influence of race and ethnicity on well-being, pain, and function after total joint arthroplasty and determined whether race, ethnicity, sex, and joint involvement influenced perceived function and pain after total joint arthroplasty.

Patients And Methods: We retrospectively reviewed the records of 1749 patients receiving total joint arthroplasty (739 hips and 1010 knees).

Quality of life and cost-effectiveness 1 year after total hip arthroplasty.

Quality of life index (Quality Of Well-Being [QWB]) was used to calculate the costs per quality of well year (QWY) in total hip arthroplasty (THA) and compare it to other interventions. Ninety-eight primary and/or revision THA were reviewed. Patients had minimum 1-year follow-up.

Patient perceived outcomes after primary hip arthroplasty: does gender matter?

Background: Total hip arthroplasty (THA) provides high functional scores and long-term survivorship. However, differences in function and disability between men and women before and after arthroplasty are not well understood.

Questions/purposes: We determined if there was a gender difference in patient-perceived functional measures and range of motion in primary THA.

The peel in total knee revision: exposure in the difficult knee.

Background: The femoral peel to expose a difficult knee was first described by Windsor and Insall in the mid-1980s. This surgical exposure consists of a complete soft tissue subperiosteal peel of the femur. It includes the detachment of the origin of the medial and lateral collateral ligaments.

Fear in arthroplasty surgery: the role of race.

Unlabelled: Understanding the difference in perceived functional outcomes between whites and blacks and the influence of anxiety and pain on functional outcomes after joint arthroplasty may help surgeons develop ways to eliminate the racial and ethnic disparities in outcome. We determined the difference in functional outcomes between whites and blacks and assessed the influence of fear and anxiety in total joint arthroplasty outcomes in 331 patients undergoing primary hip and knee arthroplasty. WOMAC, Quality of Well Being, SF-36, and Pain and Anxiety Symptoms Scale (PASS) were administered pre- and postoperatively (average 5-year followup).

Resection arthroplasty for failed patellar components.

A total of 1,401 primary total knee arthroplasties (TKA) were reviewed; 44 (3.2%) had at least the patellar component revised. Nine of these knees (eight patients) had insufficient bone stock to allow reimplantation of another patellar component.
