The role of simulation in developing surgical skills.

Surgical training has followed the master-apprentice model for centuries but is currently undergoing a paradigm shift. The traditional model is inefficient with no guarantee of case mix, quality, or quantity. There is a growing focus on competency-based medical education in response to restrictions on doctors' working hours and the traditional mantra of "see one, do one, teach one" is being increasingly questioned. The medical profession is subject to more scrutiny than ever before and is facing mounting financial, clinical, and political pressures. Simulation may be a means of addressing these challenges. It provides a way for trainees to practice technical tasks in a protected environment without putting patients at risk and helps to shorten the learning curve. The evidence for simulation-based training in orthopedic surgery using synthetic models, cadavers, and virtual reality simulators is constantly developing, though further work is needed to ensure the transfer of skills to the operating theatre.

Clinical outcomes of bilateral single-stage unicompartmental knee arthroplasty.

BACKGROUND: Deciding whether to treat patients with bilateral arthritis with two-stage or bilateral single-stage arthroplasties is a cause of considerable debate in orthopaedic surgery. METHODS: A total of 394 cemented Unicompartmental Knee Arthroplasties (UKA) were performed in this unit between 2006 and 2010. A retrospective review identified 38 patients (76 knees) who underwent bilateral Single-Stage Sequential UKA, performed by a single surgeon. RESULTS: The mean BMI was 29.8 and the majority of patients were ASA grade 2. The mean duration of follow-up was 30 months. The mean total tourniquet time was 83 min. The mean post-operative haemoglobin was 11.8 and no patient required blood transfusion. The mean time to mobilisation was 18 h and the average length of stay was 3.5 days. This compares favourably with an institutional average length of stay of two days for a single UKA. There was a significant improvement in the mean pre- to post-operative OKS (from 14 to 34, p<0.0001). One patient required operative fixation of a tibial plateau fracture after sustaining a mechanical fall two months following surgery. There were no other major complications, including thrombo-embolic events or deep infections. Two patients required excision of a superficial suture granuloma. CONCLUSIONS: Bilateral Single-Stage Sequential UKAs provide significant improvement in patient function and can be performed safely with a low complication rate. Patients can benefit from a single hospital admission and anaesthetic whilst the shorter total in-patient stay reduces costs incurred by the hospital. LEVEL OF EVIDENCE: IV.

Current concepts of the management of anterior cruciate ligament injuries in children.

Recent reports have suggested an increase in the number of anterior cruciate ligament (ACL) injuries in children, although their true incidence is unknown. The prognosis of the ACL-deficient knee in young active individuals is poor because of secondary meniscal tears, persistent instability and early-onset osteoarthritis. The aim of surgical reconstruction is to provide stability while avoiding physeal injury. Techniques of reconstruction include transphyseal, extraphyseal or partial physeal sparing procedures. In this paper we review the management of ACL tears in skeletally immature patients.
