“…Differences in both absolute wattage achieved and output proportional to the contralateral limb were highly significant ( p < 0.001), the implant group with the proposed mechanical advantage actually demonstrating superior power output compared to the contralateral limb. This is distinct from previous reports of the recovery of muscle power in the lower limb following knee arthroplasty and indeed other surgical procedures following knee injury, where the affected knee typically achieves 80–90% of the power of the contralateral limb. Interestingly, the patients in the other arm of the trial, who received an implant that did not have the theoretical mechanical advantage, achieved this figure of 90%, consistent with these previous reports.…”

We investigated whether a postulated biomechanical advantage conferred to the extensor mechanism by a change in knee implant design was detectable in patients by direct physical testing. 212 TKA patients were enrolled in a double blind randomized controlled trial to receive either a traditional implant or one which incorporated new design features. Extensor mechanism power output and physical performance on a battery of timed functional activities was assessed pre-operatively and then at 6, 26, and 52 weeks post-operatively. Significantly enhanced power output was observed in both groups post-arthroplasty; however, the new design implant group demonstrated a greater change in power output than the traditional implant group. Posthoc testing of between group differences highlighted greater improvement at all post-operative assessments. At 52 weeks, patients receiving the implant with the postulated biomechanical advantage achieved 116% of the power output of their contralateral limb, whereas patients with the traditional design achieved 90%. No between group difference was detected in the patient's time to complete functional tasks. Thus, patients receiving a knee implant of a modern design (theoretically able to confer a mechanical advantage to the extensor mechanism) were found to generate significantly greater extensor power than those receiving a traditional implant without the postulated mechanical advantage. ß

“…Correlation with Tegner activity scores was 0.56 in one study, suggesting measurement of a separate activity-related construct 28. In other studies, postoperative IKDC scores corresponded with Lysholm, Cincinnati, KOOS, and Orthopädische Arbeitsgruppe Knie (OAK) scores 9–12 15 16 19 21 24 25 27–49. However, these studies did not detail individual patient scores, and thus, correlations with the IKDC could not be quantified.…”

“…The IKDC has been widely used to measure outcomes in patients with multiligament knee injuries, while the KOOS has been less popular. We only found eight studies reporting KOOS scores in this systematic review, with several of these studies failing to report numerical scores 10 16. As a result, few conclusions could be made regarding the validity and responsiveness of the KOOS in evaluating patients with multiple ligament knee injuries.…”

“…Relatively little is known about the functional deficits in patients with the meniscus suture or its re-fixation and the possible relevance of postoperative, supervised rehabilitation [4]. Results of isokinetic muscle force examinations do not always correlate with the scores of functional assessment (one-leg rising test, one-leg-hope test) in patients treated surgically because of knee injuries [3, 28, 29]. …”

BackgroundSurgery of meniscus tear results in limitation of function. The aim of study was functional assessment of knee 1 year after surgery with two techniques in cases of the medial meniscus tear followed by the same supervised rehabilitation.Materials and methodsA total of 30 patients with good KOSS scores constituted two equal groups after partial meniscectomy or meniscus suture. Measurements of knee extensors and flexors muscles peak torques were performed with angular velocities 60, 180, 240 and 300 s−1 using Biodex IV system. One-leg-hop and one-leg-rising tests ascertained the function of operated knee. Results of examinations were compared with reference to healthy volunteers. Results of biomechanical and clinical studies were correlated to create complex and objective method evaluating treatment.ResultsExtensors peak torque values at 60 s−1 angular velocity and H/Q coefficient were decreased after meniscectomy more than meniscus suture in comparison to healthy volunteers (P ≤ 0.001; P ≤ 0.05). Analysis of functional tests revealed that patients after meniscectomy showed difference between operated and non-operated knee (P ≤ 0.01) while patients with meniscus suture differed the least to controls (P ≤ 0.05). Extensors peak torque values at 60 s−1 angular velocity correlated with results of one-leg-rising test.ConclusionResults suggest worse functional effects when meniscectomy is applied which implies modification of the rehabilitative methods in a postoperative period.
