The objectives of our study were to compare patient reported outcome measures between manual and robotic-assisted total hip arthroplasty.

Between 1st May 2021 and 31st August 2022, 539 consecutive patients who underwent 564 primary total hip arthroplasties were identified from the local registry database. Data were prospectively collected, and included patient demographics, American Society of Anaesthesiologists (ASA) grade, surgical approach, robotic-assistance, Oxford Hip Score (OHS), EQ-5D-3L and EQ-VAS pre-operatively and at twelve months.

Robotic-assistance, compared against manual total hip arthroplasty, was associated with an enhanced median (interquartile range) OHS (46 [42 – 48] vs 43 [36 – 47], p-value < 0.001), EQ-5D-3L (5 [5 – 7] vs 6 [5 – 8], p-value 0.002), and EQVAS (90 [75 – 95] vs 80 [70 – 90], p-value 0.003) at twelve months after surgery. Robotic-assistance was confirmed to be an independent predictor of a greater OHS at twelve months on a multivariate linear regression analysis (p-value 0.001).

Robotic assistance was superior to manual total hip arthroplasty in enhancing patient reported outcomes at twelve months after surgery.

Reduced length of stay (LOS) is logistically, economically and physiologically beneficial. Although a high proportion of total joint arthroplasty (TJA) patients are suitable for same day admission (SDA), removable barriers persist in many centres. This study aimed to determine factors limiting SDA and quantify the impact of implementing both SDA and a targeted enhanced recovery programme on length of stay.

This single-centre retrospective cohort study collected data on elective TJA patients aged <60. Qualitative service reviews identified opportunities for optimisation. Improvements were implemented in 2017, including: obtaining consent at the pre-assessment clinic and robustly assessing suitability for SDA. A targeted rapid recovery program was implemented in June 2018. Data was collected prior to changes in 2017, and following changes in 2018.

106 of 108 screened patients were eligible for inclusion. There were no significant between-year differences in baseline health characteristics. Significantly greater proportions of 2018 patients were consented at their pre-assessment clinic (56% vs 8.9%, p<0.001) and assessed as suitable for SDA (94% vs 57.1%, p<0.001). Pre-operative LOS was significantly reduced in 2018 for both total hip replacements (median [IQR]: 0[0,0] vs 1[1,1], p<0.001) and total knee replacements (median [IQR]: 0[0,0] vs 0[0,1], p=0.002). The departmental mean LOS improved from 4.7 days to 3.7 days following SDA. This was further shortened to 3.2 days after introduction of the rapid recovery program.

When a larger proportion of patients were deemed suitable for SDA, this correlated with reduction of LOS. The department now performs above national standards in both of these parameters.

Background

Anterior Cruciate Ligament Reconstruction is a commonly performed orthopaedic operation. The use of a four-strand semitendinosus and gracilis hamstring graft (STG) is a well established method of reconstruction to restore knee stability.

Aim

To assess the ten year subjective knee function and activity level following STG anterior cruciate ligament reconstruction.
