urpose: There is not enough information in the literature regarding the functional outcome after major hip revision surgeries. Τhis study presents a self-reported outcome analysis of 37 patients following a complex hip revision arthroplasty performed with an extended trochanteric osteotomy (ETO).
Materials and Methods: Pre- and post-operative data were collected from an electronic database with a 2-year minimum follow-up. For this purpose, standardized questionnaires with emphasis on physical function, patient satisfaction and expectations, were used. Statistical analysis was performed to compare pre- and post-operative scores and to assess any relationship between score changes and certain factors.
Results: Self-reported outcome analysis revealed a significant improvement (p<0.001) in total Harris Hip Score (76.34 versus 48.03), and Western Ontario & McMaster Universities Osteoarthritis Index scores (pain: 2.27 versus 10.00, function: 15.58 versus 30.96, summary: 20.27 versus 44.58) post-operatively. Six out of eight subcategories of 36-Item Short-Form Health Survey demonstrated a significant upgrade postoperatively. Univariate analysis revealed that Charnley class B & C patients improved significantly less in five out of eight SF-36 items; whereas age, gender, BMI, number of previous revisions, degree of femoral bone loss and stem design had no influence on score improvement in any of the outcome measures (p>0.05). Satisfaction rate was high (92%).
Conclusions: Complex hip revisions provide good mid-term functional results and good satisfaction rates. However, patients should be advised not to have unrealistic expectations regarding their post-operative activity level. Further high-quality prospective studies are needed to establish the long-term functional outcome of hip revisions using ETO.
