We had previously reported on early outcomes on a new fluted, titanium, monobloc stem with a three degree taper that has been designed for challenging femoral reconstruction in the setting of extensive bone loss. The aim of this study was to report its mid-term clinical and radiographic outcomes.

This is a retrospective review of prospectively collected data carried out at a single institution between Jan 2017 and Dec 2019. 85 femoral revisions were performed using a new tapered, fluted, titanium, monobloc (TFTM) revision stem. Complications, clinical and radiographic data were obtained from medical records and a locally maintained database. Clinical outcomes were assessed using the Oxford Hip Score (OHS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). All post-operative radiographs were analysed for subsidence, osteolysis and femoral cortical bone remodelling.

Mean follow-up was 60 months (range 28–84 months). Subsidence of 1.2 mm was noted in one patient. No cases of clinically significant subsidence (10 mm) were observed. At final follow-up, a statistically significant improvement was noted in functional outcome scores. The mean OHS preoperatively and at final follow-up were 24 (SD 13) and 42 (SD15). p = 0.04 mean difference 18 (95% CI 15–22). The mean WOMAC scores preoperatively and at final follow-up were 62 (SD23) and 88 (SD7) respectively (p < 0.001, mean difference 26; 95% CI 21–34). No stem fractures were noted within the follow-up period. Two patients had revision of the stem's one for infection and another for persistent pain.

Positive mid-term clinical and radiological outcomes have been observed with this tapered, fluted, titanium, monobloc stem. Based on these results, this implant may be considered as a viable option in the majority of uncemented femoral revisions.

The number of revision total hip arthroplasties (THA) is increasing. This procedure is associated with a higher complication rate than primary THA, and so it is important for patients to have realistic expectations. The aim of this systematic review was to gather and summarise the available evidence on patients’ expectations following revision THA.

A literature search was conducted in PubMed, PsycINFO, Cochrane, Google Scholar and Web of Science from inception to December 2021. Methodological quality was assessed by two independent reviewers using the National Heart, Lung and Blood Institute (NIH) study quality assessment tool for observational cohort and cross-sectional studies.

The search strategy generated 3132 references of which 4 articles met the inclusion criteria. Methodological quality scores ranged from 7–10. Patients have high expectations concerning future walking ability, pain and implant longevity. Implant longevity expectations vary according to the longevity of the primary implant. A significant positive correlation was found between fulfilled expectations of pain and walking ability and patient satisfaction (r = .46 – .47). Only one study assessed fulfilment of patient expectations. Great variability was seen in operationalisation and assessment of expectations.

Patients undergoing revision THA appear to have high expectations with regards to future outcomes. Whilst results are promising, there is a paucity of high-quality data in this area. Further research is needed, which places emphasis on developing a sound theoretical framework for expectations, allowing for the consistent implementation of valid measurement tools.
