Background: The Single Assessment Numeric Evaluation (SANE) is a simple, one-question patient-reported outcomemeasure (PROM). We systematically reviewed correlations between SANE and more extensive PROMs.Methods: We identified studies with correlation coefficients between SANE and other shoulder, knee, and anklespecificPROMs. We calculated mean, median and range across studies...

OBJECTIVES The present study aims to investigate the associations between malalignment and incident knee OA after 2.5 years in a high-risk group of 333 middle-aged overweight women (BMI ≥ 27 kg/m(2)) free of clinical and radiological knee OA at baseline. METHODS The primary outcome measure was the incidence of knee OA, defined as the incidence of radiographic knee OA (Kellgren and Lawrence gr...

The aims of this study were to determine the complexity of surgery required to revise failed unicompartmental knee replacements and to evaluate the outcome following revision. Between 2000 and 2009, 494 cemented Oxford phase 3 medial unicompartmental knee replacements were implanted, with 24 (4.9%) requiring revision (mean age: 63.5 years; 58% male). Mean time to revision was 3.0 years. All cas...

The purpose of this study was to compare the outcomes of manipulation under anesthesia (MUA) to arthrolysis for combat-related arthrofibrosis. Sixty-one knees in 56 patients who underwent treatment for arthrofibrosis secondary to lower extremity trauma were reviewed. Knee range of motion preoperatively, postoperatively, and at follow-up was analyzed. The primary outcome measure was the differen...

BACKGROUND AND PURPOSE There is disagreement in the literature about the importance of patellofemoral joint degeneration and knee pain for the outcome of unicompartmental knee arthroplasty (UKA). We therefore investigated the importance of selected predictors including patellofemoral joint degeneration and the location of preoperative knee pain for the early outcome of UKA. PATIENTS AND METHO...

OBJECTIVE Quantifiable outcome measures for disabling diseases such as osteoarthritis (OA) of the knee are necessary in order to compare the impact of different interventions competing for financial resources. Current subjective and questionnaire data are not satisfactory for such study. In this study, we examine the potential of the direct measurement of ambulatory activity as such a measure. ...

Even though operative microfracture is the most frequent method for treatment of limited knee joint cartilage lesions among adults, data about ouctome in children and adolescents are rare. We performed a retrospective chart review and telephone interview to analyze for the clinical outcome following knee joint cartilage defect microfracturing among 10 children. Mean postoperative Lysholm was 92...
