I have developed a new technique for Acetabular Impaction Grafting and have an excellent outcome with supportive data collected over 15 years.
The potential for research from this data is extensive.
I would benefit from some support from the Trust in terms of rationalising my workload and allocation of Junior Grades to assist with the continued research and writing papers based on the work.
I have shown examples of recent publications and presentations below.
I have numerous ideas for new papers and currently have several papers in the pipeline.

Abstract: Traumatic knee dislocation is a serious and potentially limb threatening injury that can be easily missed if meticulous history and examination have not been employed. Neurovascular injuries are common in this condition, and due diligence should be given to their thorough evaluation at the time of secondary survey so as to avoid complications such as ischaemia, compartment syndrome and eventual amputation. There is growing evidence in the literature that morbid obesity is associated with low energy knee dislocation, therefore this should be considered when assessing this cohort of patients presenting with an acute knee injury. Early operative intervention especially with multi ligaments involvement is the preferable strategy id the management of this acute injury. Controversy exists whether to reconstruct or repair damaged structures, and whether to adopt a one-stage or two-stage reconstruction of the cruciate ligaments. Early rehabilitation is important and essential to achieve satisfactory outcomes. This article is an evidence-based overview of this rare but devastating injury.
Keywords: Knee dislocation, knee injuries, knee joint, ligaments, nerve injury, vascular system injuries.
INTRODUCTION
Traumatic knee dislocation (KD) is a serious and potentially limb threatening injury, albeit a relatively rare condition, the incidence has been reported as approximately 0.02-0.2% of orthopaedic injuries [I-3J. There is some variance on the definition of knee dislocation, though it can be generally considered to include disruption of at least 2 out of 6 of the major ligamentous and cartilaginous structures, with or without instability. These injuries have historically beet ) attributed to high-velocity impacts (HVKD ) however, more recently they are being noted in low-velocity incidents (LVKD ), particularly involving morbidly obese people. There is an associated high risk of neurovascular damage particularly to the popliteal artery and the common peroneal nerve, where they are tethered by the popliteal fossa boundaries and fibular head respectively, reported to be between 20 -40% and as high as 64% for popliteal artery damage in some studies [4, 5J.
Knee dislocations (KD) often reduce spontaneously out with the emergency department, potentially leading to a high rate of delayed presentation or missed diagnosis (6, 7]. With regard to the latter, spontaneously reduced dislocations often have normal radiographs and minimal clinical signs: the physician must be vigilant and have a high index of suspicion to avoid missing the diagnosis and its potentially devastating complications. Complications of missed KD can include vascular compromise, ischaemic limb, permanent nerve damage, popliteal vessel thrombosis, acute compartment syndrome requiring decompression fasciotomies and even amputation (1, 5, 6, 8].
EPIDEMIOLOGY
The true rate of knee dislocations is not known due to the number of spontaneous dislocations [8]. Knee dislocations arc traditionally divided epidemiologically into those caused by high-velocity trauma such as an R.TA or low-velocity trauma such as those sustained in sporting injuries. KD tends to occur in younger patients and occurs in a male to female ratio of 4: 1 [8], More recently there has been literature reporting the rise of knee dislocations in the morbidly obese [9 -13]. Georgiadis et al. reported an increase in low-velocity knee dislocations in the morbidly obese from 17% between 1995-2000 to 53% in 2007- 2012 (J I]. The same study also found that obese patients with low energy knee dislocations were more likely to have neurovascular injuries requiring surgical intervention than patients with higher energy traumatic dislocations. However, traditionally, low-velocity knee dislocations have lower rates of neurovascular injury [12].
CLASSIFICATIONS
Conventionally, the dislocated knee is categorised radiographically m a positional fashion by the displacement of the tibia relative to the femur. This system was originally developed by Kennedy in 1963 [2]. It classifies dislocations into 5 types: Anterior, posterior, medial, lateral or rotatory. Rotatory subtypes are divided into anterolateral, anteromedial, posterolateral and posteromedial types. Of these, posterolateral disruptions are the most difficult to reduce [6].
