Background and Purpose
There is few reports to date that supports superior clinical
outcomes with labral refixation compared with labral
debridement in the setting of arthroscopic treatment of FAI.
The purpose of this study was to evaluate the efficacy of
labral repair in the arthroscopic treatment of FAI by
compairing with labral debridement .
Patients
Arthroscopic treatment of FAI associated with labral
pathology in 48patients( 55hips)
Single surgeon (H.O.)
group D (debridement) September 2003 - Nobember
2007 : n=11
group R ( repaired all labral tears as possible as we can. )
Nobember 2007 - October 2011 : n=37
Methods
 Outcome Measures
• JOA score (Japan Orthopedic Association hip score)
:Pain(40) + ROM(20) + Walk(20) + ADL(20)
•
Pain score ( JOA score )
 Provocation test
• Impingement sign( pre-post op.)
Methods
Debridement(Group D) vs.labral Repair(Group R)

discussion
We compared the results of labral repair and debridement in
the arthroscopic treatment of FAI.
In this study,there was no difference in total score of JOA
score,however focused on the pain score ,there was significant
difference between two groups.
These results indicated that labral refixation resulted in better
JOA pain score . Thus , it may be bound to good clinical result
and to reducing the chance of subsequently developing
osteoarthritis.
