1. Almost all patients with osteoarthritis of the hip who consult the surgeon do so because they wish to be relieved of pain. They all have limitation of movement in varying degrees but most of them will be either unaware of it or will have accepted it. What is more important, they would not have sought medical advice because of stiffness if there had been no pain. The primary objective of operative treatment must therefore be to relieve pain. 2. Displacement osteotomy will give substantial relief from pain in a high proportion of cases and the relief is lasting. Perhaps that explains why this operation, advocated by McMurray and Malkin twenty-five years ago, is being practised more widely than ever to-day while its competitors (neurectomy, capsulectomy, arthroplasty) have steadily diminished in popularity. 3. The disadvantages of the operation are all related to post-operative immobilisation in plaster, which may induce further stiffness of the hip, even to the extent of ankylosis, or stiffness and pain in the knee. These disadvantages may be overcome to a considerable degree by internal fixation followed by sling suspension and early active movement. But when, under anaesthesia, the range of hip flexion is reduced to 45 degrees or less, the operation is always liable to result in ankylosis, and it is wise in these circumstances to take this possibility into account and warn the patient beforehand

Aims

Meniscal injuries are common and often induce knee pain requiring surgical intervention. To develop effective strategies for meniscus regeneration, we hypothesized that a minced meniscus embedded in an atelocollagen gel, a firm gel-like material, may enhance meniscus regeneration through cell migration and proliferation in the gel. Hence, the objective of this study was to investigate cell migration and proliferation in atelocollagen gels seeded with autologous meniscus fragments in vitro and examine the therapeutic potential of this combination in an in vivo rabbit model of massive meniscus defect.

Aims

The aim of this study was to identify risk factors for recurrent instability of the shoulder and assess the ability to return to sport in patients with engaging Hill-Sachs lesions treated with arthroscopic Bankart repair and Hill-Sachs remplissage (ABR-HSR).

Aims

A systematic literature review focusing on how long before surgery concurrent viral or bacterial infections (respiratory and urinary infections) should be treated in hip fracture patients, and if there is evidence for delaying this surgery.

Aims

The primary aim of this study was to compare the postoperative systemic inflammatory response in conventional jig-based total knee arthroplasty (conventional TKA) versus robotic-arm assisted total knee arthroplasty (robotic TKA). Secondary aims were to compare the macroscopic soft tissue injury, femoral and tibial bone trauma, localized thermal response, and the accuracy of component positioning between the two treatment groups.

Cases are reported of two men who sustained bilateral hip injuries while undergoing convulsive therapy and of one woman who sustained bilateral hip injuries during a uraemic convulsion. A further twenty-three previously unreported cases are analysed, sixteen of which were of simultaneous bilateral femoral neck fractures and five of which were simultaneous bilateral central dislocations of the hip. One other patient sustained his injuries in an epileptic fit. A review of the literature has revealed another thirty-five cases of bilateral hip injuries, most of them caused by convulsive therapy, but a few by accident, disease of the femoral neck, or epilepsy. One case is included of a rare double injury, a femoral neck fracture on one side and a central dislocation on the other. I have found no previous reference to this combined injury. Double hip injuries are very rare in relation to the large numbers of patients receiving convulsion therapy, but the change from pharmacological to electrical methods has not prevented their occurrence and at least fifteen are known to have occurred during the last six years. A wide age range is represented, and many fractures of convulsive origin have occurred in fit, well nourished, adult men. Only a few have been found in more elderly and possibly osteoporotic patients. All the "convulsive " injuries were sustained during unmodified treatment, and mention is made of the differences of opinion among psychiatrists about the use of anaesthesia and of relaxant drugs in convulsion therapy. These are the most severe injuries complicating convulsion therapy, and the most difficult for the orthopaedic surgeon to treat

1. This paper reports the investigation and the results of a line of treatment in thirty feet showing the peroneal spastic flat foot deformity. The questions that have aroused controversy are discussed, the evidence for previous opinions is examined, and some phenomena in relation to this condition are described. 2. It is suggested that previous opinions on this condition have been misleading, and have in many cases been made after incomplete investigation of too few cases. 3. Peroneal spastic flat foot can occur without a developmental tarsal anomaly. 4. The presence of a tarsal anomaly does not necessarily mean that the foot is incorrigibly stiff, and some of these feet show a full range of movement under anaesthesia. 5. There is no evidence from this series of cases to suggest that organic nervous disease or psychiatric disturbances played a significant part in the production of the deformity. 6. There is no evidence to suggest that the deformity is a manifestation of generalised rheumatoid arthritis. 7. This investigation does not reveal the cause of the deformity when the tarsal skeleton is normal, nor does it help to explain the reason for the onset of symptoms in a developmentally abnormal foot. 8. It is suggested that a tarsal anomaly makes the foot more likely, under average stress, to break down in this way, and that this deformity is also assumed by architecturally normal feet under heavy stress. In view of the frequency of minor tarsal anomalies among this series of thirty feet, it seems likely that all feet presenting the deformity of peroneal spastic flatness are to some degree structurally abnormal, although the exact site of the abnormality may escape us

Aims

As the first wave of the COVID-19 pandemic began to dip, restarting elective orthopaedics became a challenge. Protocols including surgery at ‘green’ sites, self-isolation for 14 days, and COVID-19 testing were developed to minimize the risk of transmission. In this study, we look at risk effects of 14-day self-isolation on the incidence of venous thromboembolism (VTE) in our green site hospital among patients undergoing total joint replacement (TJR).

Aims

The aim of this study was to investigate the efficacy of coccygectomy in patients with persistent coccydynia and coccygeal instability.

Aims

The aim of this study was to determine the extent to which patient demographics, clinical presentation, and blood parameters vary in Kingella kingae septic arthritis when compared with those of other organisms, and whether this difference needs to be considered when assessing children in whom a diagnosis of septic arthritis is suspected.

Aims

Despite advances in the treatment of paediatric hip disease, adolescent and young adult patients can develop early onset end-stage osteoarthritis. The aims of this study were to address the indications and medium-term outcomes for total hip arthroplasty (THA) with ceramic bearings for teenage patients.

Aims

Modern total knee arthroplasty (TKA) prostheses are designed to restore near normal kinematics including high flexion. Kneeling is a high flexion, kinematically demanding activity after TKA. The debate about design choice has not yet been informed by six-degrees-of-freedom in vivo kinematics. This prospective randomized clinical trial compared kneeling kinematics in three TKA designs.

Aims

Intravenous dexamethasone has been shown to reduce immediate postoperative pain after total hip arthroplasty (THA), though the effects are short-lived. We aimed to assess whether two equivalent perioperative split doses were more effective than a single preoperative dose.

Aims

This study aimed to investigate whether human umbilical cord mesenchymal stem cells (UC-MSCs) can prevent articular cartilage degradation and explore the underlying mechanisms in a rat osteoarthritis (OA) model induced by monosodium iodoacetate (MIA).

Aims

The aim of this study was to investigate the hypothesis that a single dose of tranexamic acid (TXA) would reduce blood loss and transfusion rates in elderly patients undergoing surgery for a subcapital or intertrochanteric (IT) fracture of the hip.

Aims

During the COVID-19 pandemic, many patients continue to require urgent surgery for hip fractures. However, the impact of COVID-19 on perioperative outcomes in these high-risk patients remains unknown. The objectives of this study were to establish the effects of COVID-19 on perioperative morbidity and mortality, and determine any risk factors for increased mortality in patients with COVID-19 undergoing hip fracture surgery.

Aims

This observational study examines the effect of the COVID-19 pandemic upon the paediatric trauma burden of a district general hospital. We aim to compare the nature and volume of the paediatric trauma during the first 2020 UK lockdown period with the same period in 2019.
