Reconstruction of the anterior cruciate ligament in patients over 50 years.

The records of patients aged 50 years or over who underwent primary reconstruction of the anterior cruciate ligament between 1990 and 2002 were reviewed. There were 35 knees in 34 patients that met the inclusion criteria. The mean age of the patients was 57 years (50 to 66) and the mean clinical follow-up was for 72 months (25 to 173). A total of 23 knees were reconstructed with patellar tendon allograft, and 12 with patellar tendon autograft. The mean pre-operative knee extension was 1 degrees (-5 degrees to 10 degrees) and flexion was 129 degrees (125 degrees to 150 degrees) and at follow-up these values were 0 degrees (-5 degrees to 5 degrees) and 135 degrees (120 degrees to 150 degrees), respectively. Pre-operatively there were 31 knees (89%) with a Lachman grade 2+ or 3+. Post-operatively, 33 knees (94%) were Lachman grade 0 or 1+. The mean pre- and post-operative International Knee Documentation Committee scores were 39 (23 to 72) and 90 (33 to 100) respectively. The mean pre- and post-operative Lysholm scores were 50 (18 to 68) and 92 (28 to 100) respectively and the mean University of California Los Angeles activity scores were 8.5 before injury (4 to 10), 4.3 (3 to 6) after injury and 8.3 (4 to 10) post-operatively. There were three graft failures (8.6%) requiring revision. We conclude that reconstruction of the anterior cruciate ligament in carefully-selected patients aged 50 years or over can achieve similar results to those in younger patients, with no increased risk of complications.

Establishing maternal and child health data collection priorities for state and local oral health programs.

OBJECTIVE: This paper identifies specific data items for use by state and local agencies in a maternal and child oral health needs assessment model. METHODS: A modified Delphi approach was used to develop consensus on items for inclusion in the data set and their relative importance. Initially, 31 data items were chosen from several national sources. All state dental directors, along with other selected administrators and advisory committee members for this process, were asked to categorize each of the data items as core (essential), important but optional, or of lesser importance. Short comments about each data item were accepted, as were additions to the list of data items. Two rounds of comments were held. RESULTS: Eleven data items/types of information were selected as core items to be included in all needs assessments. All but one of these items were determined by the scores of the respondents. The advisory committee strongly recommended that at least one core item relate to the public's perception of oral health. Some differences in perceived importance of several items existed among the state dental directors, local dental directors, and the advisory committee. Twenty-one items were identified as being important, but optional, and seven were considered less than important and not included in the model data set. CONCLUSIONS: A modified Delphi approach facilitated the development of core and optional data items for a model oral health needs assessment. This model has potential for a common reporting mechanism so that states and local dental programs can share data.

Use of a compliance index for community fluoridation.

Fluoridation of public water supplies is the best method of preventing dental caries. Yet, many water systems do not maintain the optimal concentration of fluoride. The Community Fluoridation Compliance Index was developed to provide retrospective and prospective information on water systems in complying with local and State standards. This index permits flexibility in the amounts of optimal fluoride concentration and the frequency of fluoride sample testing. In addition, the index can be modified to address the size of the population served by the water system. The index's components are reviewed, and its use is demonstrated on 50 water systems from Illinois and 50 from Ohio. Annual data from these two States show how this information can be used for targeting corrective action so that the population receives the greatest benefit from fluoridation. These findings suggest that the Community Fluoridation Compliance Index can be a useful administrative instrument for comparing relative compliance results. Further studies to determine its acceptance at the State and local levels are warranted.
