The meta‐ analysis showed that GB techniques result ed in statistically significant improvements in the restoration of mechanical and rotational alignment and mean Knee Society Scores and Knee Society Function scores two years post‐operatively , but result ed in greater elevation of the position of the joint line .
There is no significant difference in the other radiographic data .
Conclusion This study suggests that GB may provide better radiographic and clinical outcomes than MR when used to determine mechanical rotation in TKAs
Aims There are two techniques widely used to determine the rotational alignment of the components in total knee arthroplasty ( TKA ) ;  gap balancing ( GB ) and measured resection ( MR ) .
Which technique is the best remains controversial .
We aim ed to investigate this in a systematic review and meta‐ analysis .
Functional Outcome after Computer-Assisted Total Knee Arthroplasty Using Measured Resection versus Gap Balancing Techniques: A Randomised Controlled Study
Purpose . To compare the 2-year outcome of  total knee arthroplasty ( TKA ) using the measured resection versus the gap balancing techniques . Methods . 21 men and 31 women aged 41 to 89 ( mean , 73 ) years who underwent primary TKA by a single surgeon for osteoarthritis and had an American Society of Anesthesiologists I or II physical status were prospect ively studied . Patients were r and omised to undergo computer-assisted TKA using the measured resection technique ( n=26 ) or the gap balancing technique ( n=26 ) . At the 2-year followup , patients were assessed by a single orthopaedic registrar blinded to the type of surgery using the Knee Society score ( KSS ) , functional Knee Society score ( FKSS ) , and revised Oxford Knee score ( ROKS ) . Results . In the measured resection group , the mean KSS , FKSS , and ROKS increased from 34.3 , 48 , and 21 to 85.9 , 89.6 , and 36.5 , respectively . In the gap balancing group , the respective scores increased from 35.4 , 50 , and 22.5 to 89.1 , 92.4 , and 40.6 . Postoperative with the gap balancing technique ; the respective p values were 0.46 , 0.44 , and 0.12 . Conclusion . Improvements in the knee scores were comparable with the 2 techniques
