Replacement Arthroplasty

Arthroplasties Replacement


Presentation

  • Acceptable cement mantles (A, B, C1) were present in all cases. Three femoral components (10.3%) were re-revised as a result of aseptic loosening. Two others (6.9%) were loose by radiographic criteria.[ncbi.nlm.nih.gov]
  • Three patterns of presentation of vascular injuries were recognized--immediate, early, and late, all of which require prompt recognition and appropriate treatment.[ncbi.nlm.nih.gov]
  • […] provides a 3-dimensional analysis of motion of joints as well as translation, we found that kinematics and stability of the trapeziometacarpal joint could be duplicated by joint surface replacement arthroplasty provided that normal ligament tensions were present[ncbi.nlm.nih.gov]
  • Here, we report the case of a 76-year-old male who presented with posterior dislocation after posterior stabilized revision total knee arthroplasty.[ncbi.nlm.nih.gov]
  • Odds ratios and 99% confidence intervals were calculated for relevant dichotomous outcomes and presented graphically.[ncbi.nlm.nih.gov]
Wheelchair Bound
  • At 1-year follow-up, all patients in DFR group were ambulatory while 1 in 4 in the ORIF group were wheelchair bound. Copyright 2016 Elsevier Inc. All rights reserved.[ncbi.nlm.nih.gov]
Delayed Wound Healing
  • On follow-up, no patient had delayed wound healing or wound infection. Attention to surgeon-dependent factors can offset the high risk of delayed wound healing imposed by patient-dependent factors.[ncbi.nlm.nih.gov]
Flexion Contracture
  • Contraindications to this resurfacing arthroplasty included varus-valgus instability of over 20 degrees, combined varus-valgus instability with flexion contracture of over 40 degrees, marked recurvatum, and predominant patellofemoral symptoms.[ncbi.nlm.nih.gov]
  • The flexion contracture also improved from 5.1 and 6.3 to 0.64 and 1.72 .[ncbi.nlm.nih.gov]
Foot Deformity
  • Introduction Rheumatoid arthritis (RA) is frequently associated with painful foot deformities, which is reported in 75% of patients within four years of diagnosis, increasing to approximately 90% during the course of the disease [ 1, 2 ].[journals.plos.org]
Suggestibility
  • Recent reports suggest that uncemented total hip replacement arthroplasty (THR) results in favorable short- to mid-term clinical results.[ncbi.nlm.nih.gov]
  • The aim was to investigate whether blood transfusion in primary unilateral Total Knee replacement Arthroplasty (TKA) operations was being used inappropriately locally, the resultant cost implications and suggest ways of reducing these.[ncbi.nlm.nih.gov]
  • The results of this study suggest that long-stem cemented calcar-replacement prostheses with modern cementing technique are a reasonable option in femoral revision arthroplasties involving proximal bone loss.[ncbi.nlm.nih.gov]
  • We suggest that destabilization and breakage of prostheses result from fatigue failure secondary to the torque generated at the distal radio-ulnar joint during repeated pronation and supination.[ncbi.nlm.nih.gov]
  • In the absence of a randomised controlled trial addressing the issue, certain transfusion guidelines are suggested, based on existing indirect scientific evidence.[ncbi.nlm.nih.gov]

Treatment

  • First popularized for the treatment of late-stage rheumatoid arthritis and other debilitating forms of joint disease, the current indications have expanded to include primary treatment of elbow trauma.[ncbi.nlm.nih.gov]
  • Further well designed randomised trials for the treatment of these fractures for this comparison are required.[ncbi.nlm.nih.gov]
  • OBJECTIVES: To compare replacement arthroplasty with internal fixation for the treatment of extracapsular hip fractures in adults.[ncbi.nlm.nih.gov]
  • Total hip replacement is a safe and effective treatment for transplant recipients and, in view of their limited life expectancy, should be considered at an early stage in their treatment. KEYWORDS: AKI; AVN; THRA; recipients; transplantation[ncbi.nlm.nih.gov]
  • To evaluate the association between postoperative anemia and postoperative AKI, an inverse-probability-of-treatment weighted method was used and both univariate and multivariable analyses were performed.[ncbi.nlm.nih.gov]

Prognosis

  • Prognosis Editor's note Dr Sarah Jarvis, February 2019. A new systematic review and meta-analysis in the Lancet, involving 13,212 patients, reveals that prognosis for hip replacement has improved.[patient.info]

Etiology

  • The etiology is generally of a traumatic nature and symptoms include painful, limited range of motion of the joint. If untreated, destructive joint changes may lead to a painful degenerative arthritis requiring surgical intervention.[ncbi.nlm.nih.gov]
  • No statistically significant difference was found between preoperative etiology, patient gender, or the side of the hip involved between the revised and unrevised patients.[ncbi.nlm.nih.gov]

Epidemiology

  • Epidemiology The number of hip arthroplasties is increasing with 76,500 in 2012 in the UK, a 7% increase compared to 2011 [ 4, 5 ]. The percentage of total hip arthroplasties being performed on patients younger than 60 is increasing steadily [ 6 ].[patient.info]

Pathophysiology

  • This is mainly due to technical advances and better understanding of knee pathophysiology and functions. Knee arthroplasty involves removal of the damaged, worn or diseased knee joint with an artificial joint or a prosthetic implant.[news-medical.net]

Prevention

  • It may warrant routine prevention including employment of chemoprophylaxis. However, the limitation of the reviewed data mandates large scale prospective investigation to affirm this observation.[ncbi.nlm.nih.gov]
  • […] or wire is inserted into the bone to align and immobilize fracture - weights range from 2-20 kg - increased risk of infection due to pin site and prolonged immobility - pin sites are a portal of entry of microbes and they require fastidious care to prevent[quizlet.com]
  • Over deepening of the acetabulum or leaving rim osteophytes should also be avoided to prevent impingement.[ncbi.nlm.nih.gov]
  • You may require certain modifications to prevent falling and damaging the new joint.[methodistsouthlake.com]
  • Statins, a class of drugs used to lower cholesterol levels, have been reported to help prevent the development of DVT.[ncbi.nlm.nih.gov]
