The QT autograft detected comparable rate of Lachman test > 3 mm , Pivot shift test > 3 m and instrumental laxity > 3 mm .
The QT autograft showed a lower rate of autograft failure above all .
The QT autograft detected the reduced rate of AKP than the PT .
Quadriceps tendon autograft may represent a feasible option for primary ACL reconstruction .
The purpose of the current study was to clarify the role of the quadriceps tendon ( QT ) autograft for primary ACL reconstruction .
Thus , a Bayesian network meta- analysis comparing patients undergoing a primary ACL reconstruction with QT versus patellar tendon ( PT ) and hamstring tendon ( HT ) autografts  was conducted .
Assessment of Differences Between the Modified Cincinnati and International Knee Documentation Committee Patient Outcome Scores
Background Functional outcome question naires have become a common part of patient follow-up in the orthopaedic community . The modified Cincinnati Knee Rating System and the International Knee Documentation Committee ( IKDC ) subjective scale were design ed to provide clinicians with information regarding a patient ’s functional and clinical status after knee surgery . Hypothesis The functional outcome data reported on the modified Cincinnati Knee Rating System and the IKDC subjective question naire are equivalent . Study Design Cohort study ( diagnosis ) ; Level of evidence , 2 . Methods Between 2000 and 2007 , all patients with complex knee disorders seen in our orthopaedic clinic were prospect ively followed and given simultaneously the modified Cincinnati Knee Rating System and the IKDC subjective question naires to report their functional outcomes . The total scores of each instrument were compared at each time of evaluation . As a measure of responsiveness , the st and ardized response means were calculated . A second within-patient analysis was also performed to determine if the results would be different when looked at by the patient . Results There were a total of 130 patients with a total of 444 modified Cincinnati Knee Rating System question naires and 462 IKDC subjective complete question naires included in the study .  Overall total scores on both the modified Cincinnati Knee Rating System and the IKDC subjective question naires were equivalent in a population analysis . Overall total scores showed improvement in function over time from preoperative measurement through the 2-year follow-up . The individual patient analysis demonstrated that , for a specific patient , it was possible that up to 34 % of the population would report a total score of more than 10 points difference , depending on the scale selected . Conclusion The modified Cincinnati Knee Rating System and the IKDC subjective rating question naires reported by patient population provide similar results . The practitioner who is not performing a population -based study but following individual patients for recovery will find that the individual question naires may offer different functional limitations . Individual differences were lost in the population means , with the approximate balance of positive and negative score differences masking the individual patient differences
