“…The results confirm previous findings that quadriceps improvements were greater for ACL-reconstructed patients who followed 3 days per week CEE rather than the control one. 40,41 However, in our study no statistical results were found between the two experimental groups. From rehabilitation perspective this would appear logical that a supplementary exercise program attached to the classic rehabilitation program is more effective and is more likely to minimize QD, compared with a rehabilitation one performed alone.…”

“…It has been reported that CEE improves quadriceps muscle strength at 45-and 90-degree knee angles and quadriceps accelerated reaction time at 90 degrees of knee flexion on the ACL-reconstructed knee in the early rehabilitation stage; 8 weeks following the reconstruction. 40,41 Arai et al 42 investigated, in six orthopedic patients, the effect of CE on QS by applying a proprioceptive neuromuscular facilitation (PNF) exercise, at various knee angles. The PNF-CE was significantly effective on QS at 60 degrees of knee flexion.…”

“…14,27,33,[36][37][38][39] All the above studies used a 4-to 12-week training program and only a limited number of studies have explored CE in patients following ACL reconstruction. 40,41 Nevertheless, further research should explore different exercise frequencies in CE for this patient population.…”

Cross-Exercise on Quadriceps Deficit after ACL Reconstruction

et al. 2012

Following anterior cruciate ligament (ACL) surgery significant quadriceps muscle strength deficit (QD) usually for up to 20% compared with the uninjured knee in the first 4 weeks has been reported. [1][2][3][4] And, preoperative quadriceps strength (QS) has been found as one of the important predictors for knee function for as long as 2 years after ACL reconstruction. 5-7However, so far, there is no agreement as to what is the ideal treatment for postoperative quadriceps weakness for individuals after ACL reconstruction.Quadriceps muscle activity causes anterior tibia translation between 20 and 60 degrees of knee flexion 8,9 and this is closely related to the increased ACL strain levels at these angles. 10-12 Thus, the fact that QD is greater at the knee range of 60 degrees 10-13 following ACL reconstruction, might be attributed to the interrelation between quadriceps activity and ACL strain levels following the operation graft technique. These findings seem to justify the specific focus of the exercise rehabilitation program at 60 degrees of motion, in the early Keywords ► cross-education ► bilateral training ► quadriceps deficit ► eccentric exercise ► anterior cruciate ligament AbstractA few studies concerning the improvement of quadriceps muscle strength deficit (QD) at an early stage following anterior cruciate ligament (ACL) reconstruction have been conducted whereas, ACL rehabilitation protocols based on contralateral quadriceps strength (QS) do not exist. Given these, the goals of our study were (1) to evaluate the effects of cross-eccentric exercise (CEE) on QD on ACL reconstructed knees, and (2) to explore any changes in QD following CEE provided at the frequencies of 3 or 5 times per week. For this study, 42 ACL-reconstructed patients were randomly assigned into 3 groups, two experimental and one control and followed an 8-week rehabilitation program. Additionally, the experimental groups received CEE for 3 and 5 days per week for 8 weeks in their uninjured knees. QS was evaluated with an isokinetic/isometric test, at 60 degrees of knee flexion of both limbs before and after completion of CEE. Twofactor ANOVA showed a significant improvement of QD between groups (F ¼ 5.16, p ¼ 0.01) after CEE completion on ACL reconstructed knees. Statistically significant results arose from the 3 days per week (D ¼ 18.60, p ¼ 0.01) and 5 days per week (D ¼ 15.12, p ¼ 0.04) experimental groups, whereas the control group did not yield any statistically significant differences. CEE used as an adjunct to the ACL traditional rehabilitation program at the weekly frequencies of 3 and 5 times at the early stage of reconstruction significantly improved QD.

“…Within Greece, there is a gap in the literature regarding self-reported questionnaires to evaluate functional status of osteoarthritis (OA) patients, or patients' progress pre-operatively and post-operatively. Lysholm [16] and KOS-ADL [17] previously adapted in Greek traditionally assess more acute knee injury cases. Therefore, KOOS was thought as an appropriate questionnaire for assessing more active patients undergoing TKR compared to WOMAC [11].…”

OBJECTIVES:The aim of this study was to assess the validity, reliability and responsiveness of the developed Greek version of the KOOS in total knee replacement (TKR) patients. METHODS:For the translation procedure, guidelines for cross-cultural adaptation were followed (Beaton et al, 2000). KOOS was translated into Greek independently by 3 Greek native raters (2 physiotherapists with > 5 years of clinical musculoskeletal experience and one Orthopedic surgeon).The 3 raters had a meeting where all translations were discussed and a consensus was achieved to a preliminary (synthesis) version. This version was utilized for a backtranslation (Greek to English) by another rater, an English native professional translator who had no prior knowledge of the KOOS. The synthesis and back translation were discussed in a second meeting and a consensus on a prefinal Greek version of KOOS was reached. This prefinal version was tested in a pilot study. It was administered to 10 total knee replacement (TKR) patients with variable educational levels, to confirm the comprehensibility and syntax of all questions. Following the pilot, a final meeting was organized, where all raters discussed the comments made by the patients within the pilot. There were only two points of discussion regarding a) question P4 & P5, the translation and comprehension of full flexion and extension by patients b) the translation of the word «extreme» , the 5th point of the Likertscale in questions S6-Q4. Thus, following this meeting the final version of Greek KOOS questionnaire was developed. Validation procedure:For exploring validity, reliability and responsiveness of KOOS Greek version, 51 consecutive TKR patients (mean age 72.2±7.2 years, 39 women) within the University Hospital of Patras, Greece participated in the study. KOOS's psychometric properties were evaluated according to the COSMIN checklist.Preoperative clinical status and postoperative outcomes at 2 occasions (at discharge and 10-12 days postoperatively) were evaluated using the Greek versions of the KOOS, KOS-ADL, and SF-12 Health Survey. Psychometric properties of both Greek versions of KOS-ADL and SF-12 have been previously tested and have been found satisfactory (Roos et al, 1998, Goncalves et al, 2009). All questionnaires were administered by one orthopedic surgeon. Questionnaires were self-filled.For the analysis, criterion-related validity was evaluated by Pearson's correlation. Internal consistency by Cronbach's alpha; Reliability, by intra-class correlation coefficient (ICC).The SEM was calculated on the basis of the error variance, whereas responsiveness was calculated by effect size, standardized response mean (SRM) and by relating the smallest detectable change (SDC) with the minimal important difference (MIC). RESULTS:Internal consistency: Internal consistency was excellent with Cronbach's a being 0.801 preoperatively, and 0.920 at discharge and at 2 weeks after TKR. Chronbach's a for the 5 subscales of KOOS was found 0.785 preoperatively, 0.822 at discharge and 0.781 at 2 wee...

“…The obtaining full ROM, especially hyperextension and acceptable quadriceps muscle strength before surgery, determine surgical timing and are primary goals of early postoperative rehabilitation [7,19]. Knee impairments and disability to perform activities of daily living following ACL injury or reconstruction may be assessed by the Lysholm knee score [20].…”
