Background: Total hip arthroplasty (THA) is the treatment of choice for end-stage hip osteoarthritis where the primary goal is reducing pain, better function and quality of life. As the prevalence of THA is increasing in young patients, short stems (SS) implants have been developed to preserve proximal bone stock, minimize soft tissue disruption easing future revision surgery without compromising the stability. Patient reported outcome measures (PROMs) have been recognized as valuable tools to evaluate the outcome of THA. This study aimed to evaluate patient reported outcome after THA in patients who received the short stem Furlong Evolution at St Olavs Hospital.
Material and methods: This retrospective cohort study compared PROMs preoperatively, 3 months and 1 year after primary THA in two in groups receiving the uncemented short stem (n=70) or conventional stem (n=56). Patients with a diagnosis of hip osteoarthritis (HOA) and age 16-69 years were included in the study. Clinical follow-up was registered using disease-specific and generic PROMs from a local quality registry; The Physical function Short form (HOOS-PS), Pain Numeric Rating Scale (NRS), EQ-5D, HHS and FJS-12.
Results: Mean age at 43 years in the SS group and 47 years in the CS group. Both groups had statistically significant improvement from preoperatively until 3 months for all variables measured in HOOS-PS, NRS and EQ-5D (p<0.001). There is no statistically significant difference between the two groups at any timepoint. From 3 months to 1-year postoperatively the function score HOOS-PS shows a statistically significant improvement in both groups (p<0.045). EQ-5D in the SS group shows statistically significant improvement in the same time period (p<0.003). Preoperatively, the SS group shows a non-significant lower score in NRS pain during mobilization compared to the CS group.
Conclusions: The SS achieves comparable short-term patient-reported outcomes after THA when compared with a CS. Further research including long-term follow up is needed. | |
