We continued a prospective longitudinal follow-up study of 53 remaining patients who underwent open total meniscectomy as adolescents and who at that time had no other intra-articular pathology of the knee. Their clinical, radiological and patient-reported outcomes are described at a mean follow-up of 40 years (33 to 50). The cohort of patients who had undergone radiological evaluation previously after 30 years were invited for clinical examination, radiological evaluation and review using two patient-reported outcome measures. A total of seven patients (13.2%) had already undergone total knee replacement at the time of follow-up. A significant difference was observed between the operated and non-operated knee in terms of range of movement and osteoarthritis of the tibiofemoral joint, indicating a greater than fourfold relative risk of osteoarthritis at 40 years post-operatively. All patients were symptomatic as defined by the Knee Injury and Osteoarthritis Outcome Score. This study represents the longest follow-up to date and it can be concluded that meniscectomy leads to symptomatic osteoarthritis of the knee later in life, with a resultant 132-fold increase in the rate of total knee replacement in comparison to their geographical and age-matched peers.

The aims of the study were, first, to assess the effect of a neoprene knee brace on proprioceptive acuity of normal subjects and, second, to assess the relationships between a variety of tests of proprioceptive acuity. Twenty healthy, physically active subjects had absolute error scores measured while carrying out three different established tests of proprioceptive ability (active tracking, active reproduction, and perceived angle tests) under two conditions, either with or without the presence of a neoprene sleeve. The neoprene sleeve significantly improved the degree of error scores in all tests. For the active tracking, test accuracy was improved by 28% (p = 0.004), the angle reproduction test showed a 23% increase in accuracy (p = 0.029), and the accuracy of the perceived angle test improved by 27% (p = 0.035). The relationship between magnitude of error scores between the test all showed nonsignificant low correlation.

Purpose: The purpose of this study is to evaluate the Rolimeter@ knee tester (Aircast@, Europe) as reliable and clinically sensitive tool for identifying and quantifying knee joint laxity utilising a sample of both known ACLD and normal knees. Methods: Thirty matched subjects (1 5 known ACLD and 15 normal subjects) were tested for knee joint laxity using the Polime-term. Each subject was measured at both 90" and 30" of knee flexion, by each of the six investigators. This was then repeated again by all six investigators so that inter-tester and intra-tester reliability could be examined. Results: Results showed that there was good reliability between testers, and intra-tester reliability was good for both left and right knees in both 90" and 30" of flexion. Results also demonstrated a high level of sensitivity for determining knee joint laxity in ACLD compared to normal knees. Conclusion: The Rolimeter@ knee tester is a reliable device for quantifying knee joint laxity, and is sensitive enough to identify anterior cruciate ligament deficiency.
