Relationship of wound cosmesis with patient-reported outcome measures following total hip arthroplasty
Sho Masuda, Yukihide Minoda, Hideki Ueyama, Yohei Ohyama, Ryo Sugama, Hidetomi TeraiBackground:
Although a few studies have assessed cosmetic outcomes following total hip arthroplasty (THA), none have investigated their association with hip-specific patient-reported outcome measures (PROMs). This study aimed to investigate the relationship between cosmetic outcomes and PROMs following THA.
Methods:
We included 139 cases of primary THAs for osteoarthritis of the hip with a follow-up period of at least 1 year. Cosmetic outcomes were evaluated using the Patient Scar Assessment Scale (PSAS) from the Patient and Observer Scar Assessment Scale. PROMs were assessed using the Forgotten Joint Score-12 (FJS-12) and Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ). Correlations between cosmetic outcomes and PROMs were analysed.
Results:
The mean follow-up period after THA was 24 months. The PSAS total score was negatively correlated with the FJS-12 total score (r = −0.430,
Conclusions:
Better cosmetic outcomes were associated with better PROMs after THA. However, the direction and clinical importance of the association remain unclear and warrant further investigation.
