Psychosocial impact of scars following total hip arthroplasty: a comparative study of traumatic vs. non-traumatic etiologies.

BACKGROUND

This study aims to assess the psychosocial impact of the scars resulting from total hip arthroplasties (THA) in terms of internalization and adaptation related to the etiology of the joint damage (traumatic versus non-traumatic) and the specific surgical procedure, by using a modern approach.

METHODS

A prospective study was carried out between October 2020 and September 2022, at the Orthopedics department, Bihor Emergency County Clinical Hospital in Oradea, located in North-west of Romania. Depending on diagnosis, the participants were divided into two relatively homogeneous groups: non-traumatic group with 113 subjects (55.66%) diagnosed with degenerative hip osteoarthritis and traumatic group with 90 (44.33%) patients who underwent total hip arthroplasty (THA) following a trauma.

RESULTS

The highest internalization score was noted in uncemented THA cases performed as a consequence of traumatic coxarthrosis. The ANOVA coefficients of intergroup comparisons for the participants with traumatic coxarthrosis indicate that surgical procedures have a significant influence on scar internalization [F (2, 90) = 10.046; p<0.001; η2=0.188]. Scheffe's post hoc test indicated that patients with non-traumatic coxarthrosis who underwent uncemented THA procedures presented a higher level of psychosocial internalization compared to those who underwent cemented (Mdf = 3.87; p<0.02) and revision THA (Mdf = 4.60; p<0.004), but without surprising differences compared to revision of the soft tissue (Mdf = 3.31; p<0.08).

CONCLUSIONS

The relevance of the coxarthrosis etiology for subsequent surgical interventions was emphasized in this study. Coxarthrosis has a strong impact on the psychosocial internalization of postoperative scars, which indicates a change in the perception of social support as well as the perception of the quality of life.
