Osteoarthritis is a common chronic joint disorder affecting older people. The knee is the major joint affected. The symptoms of osteoarthritis include limited range of motion, joint swelling, and pain causing disability. There are no disease modifying drugs available, and treatments are mainly focused on pain management. Total knee replacement performed at the end stage of the disease is considered the only cure available. It has been found that obese people have an increased risk to develop not only knee but also hand osteoarthritis...

BACKGROUND AND OBJECTIVES: Osteoarthrosis is a main cause of knee pain in the elderly. Pain associated with this condition is often refractory to conservative treatment. Total knee replacement may be the best option for severe pathologies; however, the occurrence of a chronic pain state after knee replacement has been well documented in the literature. The previous descriptions of the genicular nerves have been considered somewhat inaccurate. This innervation is complex and exhibits significant interindividual variability...

INTRODUCTION: There is paucity of literature about antibiotic uptake in bone grafts soaked in antibiotic solutions at room temperature in the operation theatre. We hypothesized that if bone grafts are dipped in different strengths of antibiotic solutions for sufficient period, their utilization at the target site helps in localized release of antibiotics in adequate inhibitory concentration to achieve the bacterial regression. The purpose of the study was to find out: (1) Optimum duration, strength, and volume of antibiotic solution required for dipping bone grafts at room temperature prior to the use...

Surgical site infection (SSI) is a disastrous complication after total knee arthroplasty (TKA) which can cause prosthesis loosening and may end up in septicaemia. The incidence of infection reported to be in the range of 0.3-12.4% for primary TKA. Significantly higher infection rate is found in the morbidly obese patients. The current study compared the immediate rate of post-total knee replacement wound infection in the obese versus non-obese population. The cross-sectional study was conducted at Aga Khan University Hospital (AKUH) and comprised patients undergoing TKA for primary knee osteoarthritis...

Much of the published works assessing the reliability of smartphone goniometer apps (SG) have poor generalizability since the reliability was assessed in healthy subjects. No research has established the values for standard error of measurement (SEM) or minimal detectable change (MDC) which have greater clinical utility to contextualize the range of motion (ROM) assessed using the SG. This research examined the test-retest reproducibility, concurrent validity, SEM, and MDC values for the iPhone goniometer app (i-Goni; June Software Inc...

Importance: Black patients with advanced osteoarthritis (OA) of the knee are significantly less likely than white patients to undergo surgery. No strategies have been proved to improve access to surgery for black patients with end-stage OA of the knee. Objective: To assess whether a decision aid improves access to total knee replacement (TKR) surgery for black patients with OA of the knee. Design, Setting, and Participants: In a randomized clinical trial, 336 eligible participants who self-identified as black and 50 years or older with chronic and frequent knee pain, a Western Ontario McMaster Universities Osteoarthritis Index score of at least 39, and radiographic evidence of OA of the knee were recruited from December 1, 2010, to May 31, 2014, at 3 medical centers...

Radiography is the predominant imaging modality used for the in-vivo analysis of orthopaedic implants. A major disadvantage of radiography is that the articulating joint components that are composed of radiolucent polyethylene cannot be directly visualized. Current strategies attempt to circumvent this limitation by estimating component positions and simplifying the joint system, however, these approaches lead to a number of associated errors. Thus, this study provides a method to enable the visualization of the polyethylene component of total knee replacements in radiographic images...

BACKGROUND: Dislocation after total knee arthroplasty is a rare complication and a difficult problem to address. When the flexion gap is larger than the extension gap and the collateral ligaments are injured, instability and knee arthroplasty dislocation can occur. MATERIAL AND METHODS: We report the case of a patient presenting with a posterior dislocation of a posterior-stabilized prosthesis without trauma. Frank instability in varus stress test and a positive anterior drawer test with tibial internal rotation dismissed the conservative treatment...

PURPOSE: A number of validated scores are available to monitor clinical outcome after knee arthroplasty. The current study examines whether WOMAC, KOOS, or SF-12 scores have a predictive value to identify patients that require total knee arthroplasty within 1 year. METHODS: The Osteoarthritis Initiative includes 4684 patients in two groups: incidence subcohort (Group A, n = 3284) and progression subcohort (Group B, n = 1400). A total of 278 patients reached the endpoint "unilateral knee replacement" (Group A = 96; Group B = 182)...

OBJECTIVE: To demonstrate that postoperative computed tomography (CT) is not needed if navigation is used to determine the rotational position of the femoral component during total knee replacement (TKR). METHODS: Preoperative CT, navigational, and postoperative CT data of 70 TKR procedures were analysed. The correlation between the rotational angulation of the femur measured by CT and that measured by perioperative navigation was examined. The correlation between the femoral component rotation determined by navigation and that determined by CT was also assessed...

The current treatment for patients with end-stage generalised osteoarthritis of the knee is total knee replacement. In a recent paper in Plos One the authors examined an alternative approach, namely knee joint distraction. On the basis of a model, they claim that this treatment can postpone total knee replacement for about 20 years. This would reduce the costs for the healthcare services and improve quality of life for these patients. Although these claims seem promising, the model is only based on extrapolations of short-term results of small cohort studies...

BACKGROUND/PURPOSE: Evidence suggests that more than 30% of patients post-total knee replacement (TKR) are living with participation restrictions, yet little is known about their perceptions of and factors contributing to these restrictions. The purpose of this study was to identify emergent or recurring themes behind participation restrictions after TKR. METHODS: Nineteen participants between 50 and 85 years old reporting participation restrictions 1 to 5 years post-TKR completed semistructured qualitative interviews about their participation experience after TKR...

Alkaptonuria is a rare metabolic disease caused by a partial or total deficiency of homogentisic acid oxidase, which results in excess homogentisic acid (HGA) levels. Homogentisic acid and its oxidation products can accumulate in hyaline cartilage, tendons, and ligaments. A 55-year-old male was admitted complaining of worsening chronic pain in his left knee. A radiographic evaluation showed tricompartmental end- stage osteoarthritis. A cemented total knee replacement was performed. At the 10-year follow-up, he had returned to full activity, had no knee pain, and was very satisfied with the outcome...
