    Input: Most systematic review s rely substantially on the assessment of the method ological quality of the individual trials . The aim of this study was to obtain consensus among experts about a set of generic core items for quality assessment of r and omized clinical trials ( RCTs ) . The invited participants were experts in the field of quality assessment of RCTs . The initial item pool contained all items from existing criteria lists . Subsequently , we reduced the number of items by using the Delphi consensus technique . Each Delphi round comprised a question naire , an analysis , and a feedback report . The feedback report included staff team decisions made on the basis of the analysis and their justification . A total of 33 international experts agreed to participate , of whom 21 completed all question naires . The initial item pool of 206 items was reduced to 9 items in three Delphi rounds . The final criteria list ( the Delphi list ) was satisfactory to all participants . It is a starting point on the way to a minimum reference st and ard for RCTs on many different research topics . This list is not intended to replace , but rather to be used alongside , existing criteria lists Total sagittal knee laxity and postural control in the sagittal and frontal planes were measured in 25 patients at a mean of 36 months ( range , 27 to 44 ) after anterior cruciate ligament reconstruction and in a control group consisting of 20 uninjured age- and activity-matched subjects .  Body sway was measured in the sagittal plane on a stable and on a sway-referenced force plate in single-legged stance , double-legged stance , or both , with the eyes open and closed . Postural reactions to perturbations in the sagittal and frontal planes were recorded in the single-legged stance with the eyes open . Total sagittal plane laxity was significantly greater in the anterior cruciate ligament-reconstructed knee ( 11.2 mm ; range , 6 to 15 ) than in the uninjured knee ( 8.9 mm ; range , 6 to 12 ) or in the control group ( 6.0 mm ; range , 5 to 8) . In spite of this , the patients , in comparison with the controls , exhibited normal postural control except in two variables — the reaction time and the latency between the start of force movement to maximal sway in the sagittal plane perturbations . This supports the hypothesis that rehabilitation , with proprioceptive and agility training , is an important component in restoring the functional stability in the anterior cruciate ligament-reconstructed knee The correlation between the prospect i ve course of proprioceptive improvement and knee stability after  anterior cruciate ligament reconstruction  was investigated in 38 patients . Proprioception , on the basis of the patient ’s capacity to reposition the limb accurately , was evaluated at 3-month intervals for 24 months after  hamstring graft anterior cruciate ligament surgery .  Knee stability  was evaluated concurrently with a KT-2000 knee arthrometer .  Thirty patients experienced improvement in postoperative position sense in at least one of the examinations , although eight patients had no improvement at any time . Of the 30 patients who had improvement , 28 maintained improved position sense from 18 months to the final followup . Thirty patients maintained significantly better knee stability for a postoperative period of at least 24 months . These results indicated that a minimum of 18 months after anterior cruciate ligament reconstruction may be needed for complete restoration of the proprioceptive function in knees , although the mean position sense in all patients gradually improved from 9 months . Improvement in postoperative knee stability may have facilitated recovery of proprioception The efficacy of two non-operative rehabilitation programs was studied in a consecutive r and omized controlled clinical trial of 100 patients after 12 months subsequent to an acute anterior cruciate ligament ( ACL ) injury . Follow up of r and omization to two training models was evaluated after 3 and 12 months : A self-monitored training program ( SM ) of traditional mobility and muscle strength training of the injured leg was compared to a supervised ( SV ) training model exercising postural function in closed kinetic-chains . Nearly 50 % of the patients in the SM group required supervision after 6 weeks . An intention-to-treat analysis was performed and showed significantly better values in most of the results of the supervised group at 3 and 12 months . An alternative analysis of subgroups showed a significant difference between transferred male patients and original SV male patients at 3 months but not at 12 months , indicating the importance of initial guiding after an ACL injury . No such difference was observed in the female patients 
    Output:
    
Insufficient evidence was found to support the efficacy of one exercise intervention over another .
This review has demonstrated an absence of evidence to support one form of exercise intervention against another and the use of supplementary exercises in the management of isolated ACL injuries .
