This study assessed the impact of COVID-19 on hip and distal femur fracture patient outcomes across three successive UK lockdown periods over one year. A single-centre retrospective cohort study was performed at an acute NHS Trust. Hip and distal femur fracture patients admitted within the first month from each of the three starting dates of each national lockdown were included and compared to a control group in March 2019. Data were collected as per the best practice tariff outcomes including additional outcomes as required. Data collection included COVID-19 status, time to theatre, 30-day mortality, presence of acute kidney injury (AKI) and pneumonia, and do not attempt cardiopulmonary resuscitation (DNACPR) status. Data were analyzed using an independent-samples Aims
Methods
The use of a mobile-bearing knee system is increasing in modern total knee arthroplasty (TKA). Mobile-bearing TKA improves kinematics and is reliable and capable of providing substantial benefit for patients. The aim of this study was to report independent long term results of uncemented low contact stress (LCS) mobile bearing total knee replacement We examined the outcome of 138 consecutive patients who underwent uncemented LCS total knee replacement between 1996 and 2000. Oxford knee score was noted.Introduction
Methodology
Management of hip osteoarthritis in young active patients is made more challenging by the longevity required of the prostheses used and the level of activity they must endure. The aim of this study was to compare the functional outcomes and activity levels following hip resurfacing (HR) and uncemented total hip arthroplasty (UTHA) in young active patients matched for age, gender and activity levels. 255 consecutive hip arthroplasties performed in a teaching hospital were retrospectively reviewed from which were identified 58 UTHA patients and 58 HR patients, matched for age, gender and pre-operative activity level. Mean age of patients within UTHA was 58.5 years (34 – 65) and in HR was 57.9 years (43 – 68). No patients within the study were lost to follow-up. Mean follow-up was five years. Within each group there was a statistically significant improvement in the mean UCLA score following surgery (p=0.00). In the HR Group, mean UCLA score improved from 4.2 (1–8) to 6.7 (3–10) while in the UTHA group the mean UCLA score improved from 3.4 (1–7) to 5.8 (3–10). Mean OHS improved from 44.4 (31–57) to 16.6 (12–31) in the HR group and from 46.1 (16–60) to 18.8 (12–45) in the UTHA group, p = 0.00 each group. This study found no statistically significant difference in the levels of function (p= 0.82) or activity pursued (p= 0.60) after surgery between UTHA and HR in a population of patients matched for age, gender and pre-operative activity levels. This study has shown comparable outcomes with hip resurfacing and uncemented THA in terms of both functional outcomes and activity levels in a group of young active patients. The potential complications unique to hip resurfacing may be avoided by the use of uncemented THA. In addition, uncemented THA has a longer track record.
The management of osteoarthritis of the hip in young active patients has always been challenging. This can be made more difficult because of the longevity required of the prostheses used and the level of activity they must endure. The aim of this study was to compare the functional outcomes and activity levels following hip resurfacing and uncemented THA in young active patients matched for age, gender and activity levels. A retrospective review of 255 consecutive hip arthroplasties performed in a teaching hospital was carried out. From this series we identified 58 patients who had undergone uncemented THA (Group A) and 58 patients who underwent hip resurfacing (Group B), matched for age, gender and pre-operative activity level. The mean age of patients within Group A was 58.5 years (34–65) and in Group B was 57.9 years (43–68). Mean pre-operative University of California at Los Angeles (UCLA) score in Group A was 3.4 (1–7) and in Group B was 4.2 (1–8). The mean pre-operative Oxford Hip Score (OHS) was 46.1 (16–60) and 44.4 (31–57) in Groups A and B respectively. Mean follow-up period was five years (4–7 years). In the hip resurfacing group, the mean UCLA score improved from 4.2 (1–8) to 6.7 (3–10), while in the uncemented THA group this improved from 3.4 (1–7) to 5.8 (3–10). Similarly, the mean OHS improved from 44.4 (31–57) to 16.6 (12–31) in the hip resurfacing group and from 46.1 (16–60) to 18.8 (12–45) in the uncemented THA group. This study found no statistically significant difference in the levels of function (p= 0.82) or activity pursued (p= 0.60) after surgery between uncemented THA and hip resurfacing in a population of patients matched for age, gender and pre-operative activity levels. Although there was statistically significant improvement in UCLA and OHS within each group, it was found that no group was better than the other. This study has shown comparable outcomes with hip resurfacing and uncemented THA in terms of both functional outcomes and activity levels in a group of young active patients. The potential complications unique to hip resurfacing may be avoided by the use of uncemented THA. In addition, uncemented THA has a longer track record.
