Activity Level and Subjective Knee Function 15 Years after Anterior Cruciate Ligament Injury

Abstract

Early activity modification and neuromuscular rehabilitation resulted in a good knee function and an acceptable activity level in the majority of the nonreconstructed patients. The decline in activity level of patients engaged in contact sports at the time of injury affected their subjective quality of life more than patients involved in noncontact sports.

Self-reported activity level and knee function in amateur football players: the influence of age, gender, history of knee injury and level of competition

“…[12,16,19,31] Further, several publications failed to report how the Tegner Activity Scale score was administered, [4,5,10,15,17,18,29] and a recent report on reliability, validity and responsiveness of the Tegner Activity Scale did not clearly state if the score was assessor-or patient-administered. [6] We show that older age, female gender and lowered level of competition, adjusted for each other, were associated with worse self-reported Tegner Activity Scale scores.…”

“…This scale was initially developed as an assessor-reported scale although in this study self-reported scores were obtained in conformity with some previous publications. [12,16,19,31] Subjects were instructed, both verbally and in writing, to mark the Tegner Activity Scale score best describing their current level of activity. …”

“…[28] This scale was published in 1985 as an assessor-reported outcome for evaluation of activity level in subjects suffering from anterior cruciate ligament (ACL) injury, and has been widely used also in evaluation of other knee injuries. Increasingly, the Tegner Activity Scale is used as selfreported by patients, [12,16,19,31] and several recent publications did not describe the collection mode. [4,5,10,15,17,18,29] We could however not find any study supporting the use of the Tegner Activity Scale as a self-reported outcome.…”

“…It has however been suggested that knee-related activity level decreases with increasing age, both in injured subjects and in healthy controls, but adjustment for age in longitudinal studies is currently not recommended. [1,2,16,27] Patient-reported outcomes are frequently used to assess the patient's perspective of consequences after knee injury and several instruments have been validated during the last decades. [13,20,24] One such instrument is the Knee injury and Osteoarthritis Outcome Score (KOOS), validated for ACL reconstruction, meniscectomy and osteoarthritis (OA) after meniscectomy.…”

Normalized motor function but impaired sensory function after unilateral non-reconstructed ACL injury: patients compared with uninjured controls

“…They were all from a cohort of 100 consecutive patients with ACL injury at a non-professional, recreational or competitive, activity level, who had been followed prospectively and regularly for three years (4,8,36,37), and finally at 15 years after the initial injury (2,16).…”
