e treated 21 patients with 22 dislocations of the knee by repair or reconstruction of all injured ligaments. Eight knees were treated in the acute phase (less than two weeks after injury); the remainder were treated more than six months after injury (6 to 72). Reconstructions were carried out with a combination of autograft and allograft tendons and by direct ligament repair where possible. At a mean follow-up of 32 months (11 to 77) the mean Lysholm score was 87 (81 to 91) in the acute group and 75 (53 to 100) in the delayed group. The mean Tegner activity rating was 5 in the acute group and 4.4 in the delayed group.The International Knee Documentation Committee assessment revealed no differences between the two groups. Instrumented testing of knee stability indicated better results for anterior cruciate ligament reconstructions which had been undertaken in the acute phase, but no difference in the outcome of posterior cruciate ligament reconstructions. There was no difference in the loss of knee movement between the two groups. Although the differences were small, the outcome in terms of overall knee function, activity levels and anterior tibial translation were better in those knees which had been reconstructed within two weeks of injury.J Bone Joint Surg [Br] 2003;85-B:845-51.
only patients who had a single knee operated on have been followed up. The minimum period of observation was 22 years.Among the approximately 8500 patients who had a total meniscectomy between January 1953 and June 1973, 313 aged 18 years of age or less had the procedure in one knee (0.04%). Abdon et al 1 followed up 100 of these patients during 1982 and 1983; they were considered to be a representative group since the only difference between them and those failing to attend for review was the length of time since surgery. There were 89 patients who had a single meniscectomy and 11 who had both menisci removed from the same knee. 6 The complete data and radiographs of both knees from that review were available to us. It was not possible to trace five of the 100 patients, leaving 95 for our study. Ten women and 22 men could not attend for assessment (Fig. 1); all except the five patients who could not be traced, were investigated by analysis of the hospital notes and those of the general practitioner. Half of the 32 patients not available for clinical review were contacted by telephone to confirm the accuracy of these data. We examined 63 patients (48 men and 15 women) and documented their symptoms and levels of activity.
The Rolimeter is as reproducible and reliable as the KT-1000 arthrometer. It offers a valid method for the measurement of anteroposterior translation in the knee. Higher accuracy was obtained at 20 degrees of flexion for the KT-1000 arthrometer and at 80 degrees of flexion for the Rolimeter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
