Background:
Recently a new arthroscopic based treatment paradigme for hip
related pain with radiological findings of femuroacetabular impingement and
labral lesions has evolved.
Purpose / Aim of Study:
purpose of this prospective study was to present
clinical outcome from patients treated arthroscopically for hip related pain
suspected to be due to femuroacetabular impingement.
Materials and Methods:
123
consecutive patients operated in 2009-2011 are
included in this prospective case series (59 % female; mean age 36 years). The
indication for arthroscopic treatment of hip related pain was mechanical hip
symptoms and radiological findings of femuroacetabular impingement. To
evaluate hip function and pain level at 1 year follow-up MHHS (Modified
Harris Hip Score), HOS (Hip Outcome Score) and pain score were used.
Findings / Results:
Labrum tears were seen in 87 % of the hip arthroscopies.
Cartilage lesions (ICRS grade 2 and above) were seen at the Acetabulum and
Caput in 68 % and 22 % of cases respectively. In 95 % of the arthroscopies
cheilectomi and/or acetabular rimtrimming were performed. In 72 % of
procedures the labral reattachment was performed. The patient evaluated
outcome demonstrated significant increases in MHHS and HOS at 1 year
follow up compared to preoperatively. (MHHS: 58,3 to 73,6, HOS: 66,7 to
81,5).
Pain levels decreased significantly form pre-operatively to follow up.
5%
patients had a total hip replacement within the follow-up period.
Conclusions:
Arthroscopic treatment of FAI improves patient evaluated
outcome. Further studies are needed to determine failure rates and risk factors
for failures.
