“…It is generally believed that the proper function of knee depends mainly on its extensors and flexors peak torque values and their mutual relationships [4]. These force values depend on the number and sequences of the proprioceptive signals transmitted from the meniscus mechanoreceptors [13].…”

“…Partial resection of the injured meniscus, its suture or re-fixation are commonly applied in cases of the knee meniscus tear [1–4]. Partial meniscectomy is performed more frequently but results in significant functional deficits, mainly the decrease of muscle force in knee extensors [3, 5].…”

“…The restoration of complete knee function after surgery lasts some weeks, especially in patients after the meniscus suture or its re-fixation. This limitation of activity increases the thigh-muscle force deficits [3, 4, 16]. …”

“…On the other hand, other researchers recommended application of early rehabilitation [4, 11, 15, 16, 27]. 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.
