Objective To date, apart from groin and thigh pain, there is a paucity of data regarding the association between transobturator tape (TOT) surgery and lower extremity function. We have aimed to evaluate the association between TOT and various indices of hip joint pain and function. Design Prospective cohort study Settings and Population 37 patients who underwent TOT surgery for the treatments of stress urinary incontinence (SUI). Methods Various tests and questionnaires aimed to assess hip function and surgery outcomes were completed before and after the TOT surgery, at the post-operative clinic. Paired data were compared using the paired sample t-test, after testing for normal distribution. Main Outcome Measures Hip range of motion (ROM), joint function and muscle strength, walking functions, leg length, subjective effect of surgery on patients’ quality of life and the impact of urinary incontinence on daily activities, mental and physical quality of life. Results Decrease in ROM was observed in most cardinal movements of the hip. An increase in leg length following TOT was observed (mean difference in centimeters for both legs 0.87-0.88; p<0.001). An overall trend of decreased strength was noticed, significant for hip adduction. The IIQ-7 and UDI-6 questionnaires demonstrated a significant improvement in urinary function (31.95- and 25.27-point reduction respectively; p<0.05 for both). No significant change was noted in gait function following surgery. Results of the FJS assessment revealed no difference in patient’s awareness of their hip joint. Conclusion Our findings provide support for a yet underestimated association between TOT surgery and hip dysfunction.
