Recurrent groin pain following periacetabular osteotomy (PAO) is a challenging problem. The purpose of our study was to evaluate the position and dynamics of the psoas tendon as a potential cause for recurrent groin pain following PAO. Patients with recurrent groin pain following PAO were identified from a single surgeon series. A total of 13 patients with 18 hips (4.7%) out of a 386 PAO, had recurrent groin pain. Muscle path of the psoas tendon was accurately represented using 3D models from CT data were created with Mimics software. A validated discrete element model using rigid body springs was used to predict psoas tendon movement during hip circumduction and walking.Abstract

The extent to which hip arthroscopy (HA) treatments influence sexual function is not well described and limited to small cohorts. This study aims to describe trends in self-reported reported sexual function before and after HA. Adult (≥18 years) patients who underwent HA between 1/01/2012 and 31/10/2020 were extracted from the UK Non-Arthroplasty Hip Registry. International Hip Outcome Tool 12 (iHOT-12) questionnaires were collected pre-operatively and at 6 and 12 months. The iHOT-12 then asks asking patients to quantify ‘how much trouble they experience with sexual activity because of their hip?’ with responses converted to a continuous scale (0–100) to measure function.Abstract

Since its introduction in 2007 the UKITE exam has been an annual event in the diary of Orthopaedic trainees. It aims to simulate the written FRCS (T&O) examination style and offers trainees practice, immediate feedback and an update of the progress they have made through their training. It also allows bench marking against their peers nationally. The editorial process has been overhauled to allow online editing of questions throughout the year, and this has streamlined the question selection process. The fifth edition of UKITE was held in December 2011. 669 trainees and 35 non-trainees sat for the examination. Consistently over the five years of UKITE we have seen a similar distribution of results showing improving performance until the final year (64.5% for 2011) and a drop in the performance in the last year (56.6% for 2011). Overall 80% of the trainees felt the exam was fair and better than last year. 80% of the trainees who had sat FRCS (T&O) previously thought that the UKITE 2011 was similar in difficulty. 98% trainees want to sit it again and 95% thought there was educational value in sitting the exam. Over 93% were satisfied with central and local provisions made for the exam. Some examining centres in NHS hospitals faced server failure issues and provision was made to sit for their trainees to sit un-invigilated from home. The mean score for the invigilated examination (53.6%) was significantly (p< 0.001) lower than that of un-invigilated examination (63.6%). UKITE continues to evolve and has become a regular feature in the post-graduate orthopaedic calendar. It is perceived as a useful way of revising and maintaining a core level of knowledge as part of the exam preparation.

It aims to simulate the written FRCS (T&O) examination style and offers trainees practice, immediate feedback and an update of the progress they have made through their training. It also allows bench marking against their peers nationally. UKITE 2010 has made further progress and for the first time trainees from all the deaneries in UK participated. A total of 645 trainees appeared for the examination that was held in December 2010. We introduced remote access from home for trainees (N=171, 26.5%) who could not appear in an “examination centre”. An online editorial process was also introduced, which made the work of the question editing team easier. The scores ranged from 25.5 to 93.4% with a mean of 54.2% (sd=11.8). The score consistently improved from ST1 (41.8%) to ST7 (64.3%) level and then declined at ST8 (54.7%) level. The mean score for candidates sitting at home (53.3%, sd=11.4) was similar (p=0.23) to those sitting at an invigilated examination venue (54.6%, sd=11.9). The extreme low and high scores were more frequent invigilated exam. The feedback suggested that 95% trainees felt that UKITE has educational benefit and 98% wish to sit again. 75% want it as an annual self-assessment tool. 80% feel that it was better than last year and of those who had sat FRCS (T&O) nearly 80% felt it was very similar. UKITE continues to evolve and has become a regular feature in the post-graduate orthopaedic calendar. It is perceived as a useful way of revising and maintaining a core level of knowledge as part of the exam preparation.
Although classic teaching holds that the least amount of constraint should be implanted, there is very little in the literature to substantiate this. This study attempts to quantify the influence of constraint and various indications upon functional outcome following aseptic first time revision knee arthroplasty. The null hypothesis was that the level of constraint and indication for surgery would not influence the functional outcome following revision knee replacement. A single centre prospective study was performed to examine the outcome for 175 consecutive total revision knee replacements performed between 2003 and 2008 with a minimum follow-up of two years. Patient reported outcome data was used to determine the influence of final level of component constraint and its relationship with primary indication for surgery.Purpose

Cemented stems have shown 90–100% survivorship when coupled with polyethylene acetabular component. This study aims to compare cemented stem behaviour in combination with large metal on metal (MOM) vs. metal on poly (MOP) bearings. 100 patients were recruited into a single centre RCT (we required 40 in each group for power .90 to confirm stem subsidence of >0.5mm at 2 years; p< 0.05). Recruits were randomized to MOP (28mm) or MOM femoral heads with CPCS cemented femoral stem. Assessments included X-rays (AP pelvis), Harris Hip Scores, blood metal ion levels and patient questionnaires (WOMAC, SF-36, satisfaction questionnaire). Evaluations were done pre-operatively and 3, 12 and 24 months post operatively; blood metal ion measures at 1 year.Introduction
