Randomized Controlled Trial of Sensor-Guided Knee Balancing Compared to Standard Balancing Technique in Total Knee Arthroplasty

BackgroundDespite advances in total knee arthroplasty (TKA) technology, up to 1 in 5 patients remain dissatisfied. This study sought to evaluate if sensor-guided knee balancing improves postoperative clinical outcomes and patient satisfaction compared to a conventional gap balancing technique.MethodsWe undertook a prospective double-blind randomized controlled trial of patients presenting for elective primary TKA to determine a difference in TKA soft tissue balance between a standard gap balancing (tensiometer) approach compared to augmenting the balance using a sensor-guided device. The sensor-guided experimental group had adjustments made to achieve a balanced knee to within 15 pounds of intercompartmental pressure difference. Secondary outcomes included differences in clinical outcome scores at 6 months and 1 year postoperative, including the Oxford Knee Score and Knee Society Score and patient satisfaction.ResultsThe sample comprised of 152 patients, 76 controls and 76 experimental sensor-guided cases. Within the control group, 36% (27/76) of knees were unbalanced based on an average coronal plane intercompartmental difference >15 pounds, compared to only 5.3% (4/76) within the experimental group (P < .0001). There were no significant differences in 1-year postoperative flexion, Knee Society Score, or Oxford scores. Overall, TKA patient satisfaction at 1 year was comparable, with 81% of controls and experimental cases reporting they were very satisfied (P = .992).ConclusionDespite the use of the sensor-guided knee balancer device to provide additional quantitative feedback in the evaluation of the soft tissue envelope during TKA, we were unable to demonstrate improved clinical outcomes or patient satisfaction compared to our conventional gap balancing technique.     

Does patient perception of alignment affect total knee arthroplasty outcome?

OBJECTIVE: This study was designed to address a recurring observation in our centre that, despite a satisfactory postoperative radiographic limb alignment, some patients are dissatisfied with the alignment and appearance of their operated leg. We carried out a prospective survey to determine patient perception of limb alignment after total knee arthroplasty (TKA) and whether level of satisfaction with alignment affects clinical outcome. METHODS: Patients self-rated their alignment, their satisfaction with alignment and their level of knee pain on a visual analogue scale (VAS). Additional outcome measures included pre- and postoperative Knee Society Score (KSS), Oxford Knee Score (OKS) and the Health Survey Short Form (SF-12). RESULTS: Twenty of 87 (23%) patients were dissatisfied with their new leg alignment and had a poorer perception of pain and range of motion after TKA. Despite this finding, KSS and OKS were no different between patients who were satisfied and those who were dissatisfied with their limb alignment. The SF-12 showed a trend toward lower scores in patients who were dissatisfied with their limb alignment. CONCLUSIONS: Satisfaction with perceived limb alignment appears to influence outcome after TKA and is not reflected in current outcome scales. Perhaps patients should be counselled on how alignment is restored and on what to expect of their limb alignment and appearance after TKA.     

Planning for children whose parents are dying of HIV/AIDS. American Academy of Pediatrics. Committee on Pediatric AIDS, 1998-1999

Although the character of acquired immunodeficiency syndrome is changing into a chronic illness, it is estimated that by the end of this century, 80 000 children and adolescents in the United States will be orphaned by parental death caused by human immunodeficiency virus infection. Plans for these children need to be made to ensure not only a stable, consistent environment that provides love and nurturing, but also the medical and social interventions necessary to cope with the tragic loss. Pediatricians should become aware of local laws and community resources and initiate discussion early in the course of parental illness to facilitate planning for the future care and custody of the children. States need to adopt laws and regulations that provide flexible approaches to guardianship and placement of children orphaned by acquired immunodeficiency syndrome.     

Continuing professional development of physicians in Uruguay: lessons from a countrywide experience

This article describes the advancement of continuing professional development (CPD) for physicians in Uruguay and explains the motivations for a CPD system, the role of the faculty of medicine and the other stakeholders, the strategic goals, and current results, including strengths and weaknesses. The work described here had three strategic objectives: (1) initiate a CPD accreditation program, (2) train physician leaders in CPD, and (3) promote the creation of a national system for CPD. By the end of 2006, the accreditation program had 34 accredited institutions. Over a 10-year period, 150 physician leaders from different regions of the country and with different specialties had been trained in the framework and methodological issues of CPD. Legislation is expected to be introduced into parliament during 2007 for coordinating CPD efforts at a national level.     

Treatment of traveler's diarrhea with ciprofloxacin and loperamide.

To determine the efficacy of loperamide given with long- and short-course quinolone therapy for treating traveler's diarrhea, 142 US military personnel were randomized to receive a single 750-mg dose of ciprofloxacin with placebo, 750 mg of ciprofloxacin with loperamide, or a 3-day course of 500 mg of ciprofloxacin twice daily with loperamide. Culture of pretreatment stool specimens revealed campylobacters (41%), salmonellae (18%), enterotoxigenic Escherichia coli (ETEC, 6%), and shigellae (4%). Of the participants, 87% completely recovered within 72 h of entry. Total duration of illness did not differ significantly among the three treatment groups, but patients in the 3-day ciprofloxacin plus loperamide group reported a lower cumulative number of liquid bowel movements at 48 and 72 h after enrollment compared with patients in the single-dose ciprofloxacin plus placebo group (1.8 vs. 3.6, P = .01; 2.0 vs. 3.9, P = .01). While not delivering a remarkable therapeutic advantage, loperamide appears to be safe for treatment of non-ETEC causes of traveler's diarrhea. Two of 54 patients with Campylobacter enteritis had a clinical relapse after treatment that was associated with development of ciprofloxacin resistance.
