1. The Moe plate has been used in 256 of 270 consecutive intertrochanteric fractures of the femur. There was an operative mortality of l8·8 per cent and an overall mortality of 20·7 per cent in a group averaging 75·2 years of age. 2. The method proved satisfactory, giving secure fixation and also approximation of the fragments by the lag action of the three large screws driven into the head. There was only one case of non-union. 3. In the survivors anatomical and functional results have been satisfactory in about 70 per cent, with half of these showing full functional recovery and the other half requiring only occasional use of a stick or crutch. 4. There are a few intertrochanteric fractures of the femur too comminuted for any form of internal fixation. Traction should be used in this group. 5. A varus deformity developed in about one half of the cases. This is consistent with a good functional result. 6. The main difficulty in these aged people has been survival. The problems have been discussed with suggestions that may perhaps reduce in part a mortality that seems inherent in this injury and at this age

We report the results of a prospective randomised trial which assessed the role of the posterior cruciate ligament (PCL) following total knee replacement (Genesis I; Smith and Nephew, Memphis, Tennessee). Over a four-year period, 211 patients underwent total knee replacement by the senior author (TJW). They were randomised at surgery to have the PCL either retained, excised or substituted with a posterior stabilised insert. If it was not possible to retain the ligament due to soft-tissue imbalance, it was released from its tibial insertion until suitable tension was obtained. This created a fourth group, those who were intended preoperatively to have the ligament retained, but in whom it was partially released as a result of findings at the time of surgery. All patients were evaluated using the Knee Society rating system (adapted from Insall). A total of 188 patients (212 knees) was available for follow-up at a mean of 3.5 years after surgery. Preoperatively, there was a varus deformity in 191 knees (90%) and a valgus deformity in 21 (10%). There were no statistical differences in the knee or function scores or the range of movement between the excised, retained and substituted groups. There were, however, significantly worse knee and function scores in the group in whom the PCL was released (p = 0.002)

We performed an audit of 71 children with consecutive displaced, extension-type supracondylar fractures of the humerus over a period of 30 months. The fractures were classified according to the Wilkins modification of the Gartland system. There were 29 type IIA, 22 type IIB and 20 type III. We assessed the effectiveness of guidelines proposed after a previous four-year review of 83 supracondylar fractures. These recommended that: 1) an experienced surgeon should be responsible for the initial management; 2) closed or open reduction of type-IIB and type-III fractures must be supplemented by stabilisation with Kirschner (K-) wires; and 3) K-wires of adequate thickness (1.6 mm) must be used in a crossed configuration. The guidelines were followed in 52 of the 71 cases. When they were observed there were no reoperations and no malunion. In 19 children in whom they had not been observed more than one-third required further operation and six had a varus deformity. Failure to institute treatment according to the guidelines led to an unsatisfactory result in 11 patients. When they were followed the result of treatment was much better. We have devised a protocol for the management of these difficult injuries

1 . A new surgical approach to the treatment of pes cavus is suggested. The operation consists in a subcutaneous division of the contracted plantar fascia and correction of the varus deformity of the heel by removing a wedge from its lateral aspect. It is submitted that, by approaching the deformity from behind and overcoming the varus of the heel, the foot is rendered plantigrade and that thereafter weight bearing exerts a corrective influence which results in progressive improvement of the deformity. The operation is essentially a prophylactic one and, for the best results, it should be performed before there is gross structural deformity and while active growth is still taking place. 2. Even in patients over the age of fourteen, improvement is obtained by doing nothing more than this simple operation. In the presence of fixed deformity of the forefoot, as encountered in older patients, inversion is corrected by removing a lateral wedge from the calcaneum and the cavus by taking a dorsal wedge from the tarso-metatarsal region. This has the double advantage of producing good correction of deformity, while at the same time preserving movement at the mid-tarsal-subtalar joint. Fixed clawing of the toes will require appropriate corrective treatment, but if the toes are malleable the simple effect of weight bearing on the plantigrade foot produces gradual correction

Aims

The patient-acceptable symptom state (PASS) is a level of wellbeing, which is measured by the patient. The aim of this study was to determine if the proportion of patients who achieved an acceptable level of function (PASS) after medial unicompartmental knee arthroplasty (UKA) was different based on the status of the anterior cruciate ligament (ACL) at the time of surgery.

Displaced extension supracondylar fractures of the elbow 1. One hundred and ten children were treated by reduction and stabilisation by two pins inserted laterally at an angle of 30 degrees to one another. 2. The complications before and after treatment included fifteen nerve lesions in thirteen patients. The ulnar nerve was involved on one occasion only. Solitary radial nerve injuries occurred with postero-medial displacement of the distal fragment, while median nerve and brachial artery injuries were associated with postero-lateral displacement. All the lesions recovered spontaneously. 3. There were no ischaemic complications after treatment, despite the ligation of one ruptured brachial artery. 4. The average stay in hospital was four days, compared with twenty days for thirty-two other patients treated in traction because of gross oedema. 5. Of eighty patients seen six months to five years after the fracture, seventy (or 87·5 per cent) had excellent or good results, seven patients with marked varus deformities had fair results, and two patients had poor results with very stiff elbows. Displaced flexion fractures 1. The clinical features, complications and treatment of seventeen cases are described. 2. There were no complications involving the median or radial nerves or the brachial artery, but three patients had a lesion of the ulnar nerve. 3. Nine children had closed reduction and fixation by two lateral percutaneous pins. 4. Reduction was difficult and the results poor compared with extension fractures. Closed reduction failed in one-third of the children, and the functional and cosmetic results were unsatisfactory in over half the patients reviewed

Aims

Nearly 99,000 total knee arthroplasties (TKAs) are performed in UK annually. Despite plenty of research, the satisfaction rate of this surgery is around 80%. One of the important intraoperative factors affecting the outcome is alignment. The relationship between joint obliquity and functional outcomes is not well understood. Therefore, a study is required to investigate and compare the effects of two types of alignment (mechanical and kinematic) on functional outcomes and range of motion.

Aims

Temporary epiphysiodesis (ED) is commonly applied in children and adolescents to treat leg length discrepancies (LLDs) and tall stature. Traditional Blount staples or modern two-hole plates are used in clinical practice. However, they require accurate planning, precise surgical techniques, and attentive follow-up to achieve the desired outcome without complications. This study reports the results of ED using a novel rigid staple (RigidTack) incorporating safety, as well as technical and procedural success according to the idea, development, evaluation, assessment, long-term (IDEAL) study framework.

Aims

Eight-plates are used to correct varus-valgus deformity (VVD) or limb-length discrepancy (LLD) in children and adolescents. It was reported that these implants might create a bony deformity within the knee joint by change of the roof angle (RA) after epiphysiodesis of the proximal tibia following a radiological assessment limited to anteroposterior (AP) radiographs. The aim of this study was to analyze the RA, complemented with lateral knee radiographs, with focus on the tibial slope (TS) and the degree of deformity correction.

Aims

A comprehensive classification for coronal lower limb alignment with predictive capabilities for knee balance would be beneficial in total knee arthroplasty (TKA). This paper describes the Coronal Plane Alignment of the Knee (CPAK) classification and examines its utility in preoperative soft tissue balance prediction, comparing kinematic alignment (KA) to mechanical alignment (MA).

Aims

Preoperative talar valgus deformity ≥ 15° is considered a contraindication for total ankle arthroplasty (TAA). We compared operative procedures and clinical outcomes of TAA in patients with talar valgus deformity ≥ 15° and < 15°.

Aims

The primary aim of the study was to compare the knee-specific functional outcome of robotic unicompartmental knee arthroplasty (rUKA) with manual total knee arthroplasty (mTKA) for the management of isolated medial compartment osteoarthritis. Secondary aims were to compare length of hospital stay, general health improvement, and satisfaction between rUKA and mTKA.

Aims

To compare patients undergoing total knee arthroplasty (TKA) with ≤ 80° range of movement (ROM) operated with a 2 mm increase in the flexion gap with matched non-stiff patients with at least 100° of preoperative ROM and balanced flexion and extension gaps.

Aims

The use of technology to assess balance and alignment during total knee surgery can provide an overload of numerical data to the surgeon. Meanwhile, this quantification holds the potential to clarify and guide the surgeon through the surgical decision process when selecting the appropriate bone recut or soft tissue adjustment when balancing a total knee. Therefore, this paper evaluates the potential of deploying supervised machine learning (ML) models to select a surgical correction based on patient-specific intra-operative assessments.

Aims

The removal of the cruciate ligaments in total knee arthroplasty (TKA) has been suggested as a potential contributing factor to patient dissatisfaction, due to alteration of the in vivo biomechanics of the knee. Bicruciate retaining (BCR) TKA allows the preservation of the cruciate ligaments, thus offering the potential to reproduce healthy kinematics. The aim of this study was to compare in vivo kinematics between the operated and contralateral knee in patients who have undergone TKA with a contemporary BCR design.

Aims

A significant percentage of patients remain dissatisfied after total knee arthroplasty (TKA). The aim of this study was to determine whether the sequential addition of accelerometer-based navigation for femoral component preparation and sensor-guided ligament balancing improved complication rates, radiological alignment, or patient-reported outcomes (PROMs) compared with a historical control group using conventional instrumentation.
