Introduction. Knee arthroscopy can be used for ligamentous repair, reconstruction and to reduce burden of infection. Understanding and feeling confident with knee arthroscopy is therefore a highly important skillset for the orthopaedic surgeon. However, with limited training or experience, furthered by reduced practical education due to COVID-19, this skill can be under-developed amongst trainee surgeons. Methods. At a single institution, ten junior doctors (FY1 to CT2), were recruited as a part of a five, two-hour session, training programme utilising the Simbionix® ARTHRO Mentor knee arthroscopy simulator, supplemented alongside educational guidance with a consultant orthopaedic knee surgeon. All students had minimal to no levels of prior arthroscopic experience. Exercises completed included maintaining steadiness, image centring and orientation, probe triangulation, arthroscopic knee examination, removal of loose bodies and meniscectomy. Pre and post experience questionnaires and quantitative repeat analysis on simulation exercises were undertaken to identify levels of improvement. Results. Comparing pre and post experience questionnaires significant improvements in levels of confidence were noted in the following domains: naming arthroscopic instruments, port positioning and insertion, recognising normal anatomy arthroscopically, holding and using arthroscopic instruments and assisting in a live theatre setting (p<0.05). Significant improvements were also noted in time taken to complete and distance covered in metres, of the simulated exercises on repeat performance (p<0.05). Conclusion. Overall, with only five sessions under senior guidance, using a simulator such as the ARTHRO Mentor, significant improvements in both levels of confidence and skill can be developed even among individuals with no prior experience

Background. The functional outcome and risk of recurrence following arthroscopic stabilisation for recurrent anterior shoulder instability is poorly defined in large prospective outcome studies. This is the first study to prospectively evaluate these outcomes in patients who have been treated using this technique. Methods. We performed a prospective study of a consecutive series of 302 patients (265 men and 37 women, mean age 26.4 years) who underwent 311 (9 bilateral) arthroscopic Bankart repairs for recurrent anterior instability. Patients were evaluated preoperatively and postoperatively at 6 months, and annually thereafter. The chief outcome measures were risk of recurrence and the two-year functional outcomes (assessed using the WOSI and DASH scores). Results. On survival analysis, the overall re-dislocation rate after surgery was 13.5% (42/311 shoulders). The median time to recurrence was 12 months (range 3 to 110 months) and 55% of these developed recurrent instability within 1 year of their surgery. The median follow-up in those patients who did not re-dislocate was 70 months. There was a significant improvement in the WOSI and DASH scores at 2 years postoperatively of 21.4 and 9.9 points respectively (both p<0.001). The risk of redislocation was significantly increased by the presence of glenoid bone loss associated with or without a Hill-Sachs lesion, and the type and engagement of a Hill-Sachs lesion on arthroscopic examination (all p<0.001). However, the risk in these sub-groups was lower than that reported in previous studies. A multivariate model was produced from these parameters to estimate the risk of recurrence at the time of primary surgery. Conclusions. The majority of patients have successful functional outcomes and relatively low risk of recurrence following arthroscopic stabilisation. The identification of preoperative factors which increase the risk of instability has enabled us to better counsel patients of their risk of failure following arthroscopic repair

Aim. To evaluate the correlation between the clinical Kirk Watson test and arthroscopic Geissler classification in scapholunate instability. Methods. All patients undergoing wrist arthroscopy between April 2006 and April 2010 were evaluated. Patients were included in the study if they had a Kirk Watson test and a wrist arthroscopy with an assessment of the stability of the scapholunate joint using the Geissler classification. Patients who had a Kirk Watson test performed with subsequent normal scapholunate joint at arthroscopy were included as a control group. Geissler grades 1 and 2 and grades 3 and 4 were grouped for further analysis into low and high grade instability groups respectively. Results. 76 patients were included in the study. 62 had scapholunate pathology and 14 had normal arthroscopic examinations of the stability of the joint. A positive test was found in 30% (3) of patients with grade 1 instability, 29% (4) with grade 2, 60% (12) with grade 3 and 78% (14) with grade 4 instability demonstrated at arthroscopy. The test was positive more commonly in those with grade IV instability compared with others (78% vs. 43%; p=0.015). There was a higher number with a negative test in the low grade instability group (71% vs. 32%; p=0.01) and a higher number with a positive test in the high grade instability group (68% vs. 29%; p=0.006). The test was most sensitive (78%) and most specific (57%) for those classified with Geissler grade IV instability and sensitivity and specificity were also high for those with high grade instability (68% and 66% respectively). Conclusions. The Kirk Watson test is a sensitive and specific test for diagnosis of higher grade instability of the scapholunate joint. We found a positive correlation between increasing scapholunate instability when assessed using the Geissler classification and positivity of the test. This confirms that the Kirk Watson test can be a useful test in the assessment of those with symptomatic instability of the joint and may reflect damage not only to the scapholunate ligament but to the secondary stabilisers of the joint as well

Shoulder pain or loss of normal range of motion is a frequent complaint in the outpatient clinic. Of these presentations, rotator cuff injury is a common cause. This can range from mild, transient inflammation of the tendons, to partial tears of tendons, or even full thickness tears. Disruption of the tendons can occur from forceful forward throwing actions undertaken in some sports, for example baseball pitching, more commonly in the UK however, chronic impingement can lead eventually to a tendon tear-usually seen in an older population. Current methods of investigation of such injuries after clinical history and examination, includes plain film radiography, ultrasonography, magnetic resonance imaging and arthrography. We decided to look at how ultrasound can be used in the district general hospital for investigation of such injuries. Aims. To determine the accuracy of ultrasound as an investigative tool for clinically suspected rotator cuff tears. Methods. Seventy-five consecutive ultrasonographic study reports, in patients who subsequently underwent arthroscopic examination, were scrutinised and correlated with surgical findings. From this, sensitivity and specificity of ultrasound at this district general hospital were calculated. In addition, this data was compiled for each of the three Consultant Radiologists in order to assess the operator dependent nature of ultrasound. Results. Of the 74 cases analysed, 43 (58.1%) had full correlation with the arthroscopy findings, 13 (17.6%) had mixed correlation, and 18 cases (24.3%) had no correlation between the ultrasound and arthroscopy report. The sensitivity and specificity of ultrasound at our institution was 0.76 and 0.8 respectively with regards to a tear being detected at ultrasound and then visualised during surgery. Conclusions. There is no current national guidance as to which imaging modality should be first line following clinical examination. Magnetic resonance arthrography, widely thought of as being the gold standard investigation, is not only expensive and possible only in certain centres, but is also invasive, time consuming, and has many relative contraindications. Ultrasound offers a clinical advantage by allowing the radiologist to speak to the patient and assess their range of motion whilst performing the study. This interaction is lost totally in MRI, CT and even MR arthrography. Our study shows that ultrasonography can be quite accurate in identifying a rotator cuff tear. Although it is operator-dependent, ultrasound should be considered more often as a first-line imaging tool for suspected rotator cuff tears as it is relatively inexpensive, quick, and most importantly dynamic

We have compared the results at a mean follow-up of 13 years (11 to 14) of two groups of supination-external rotation type-4 fractures of the ankle, in one of which there was a fracture of the medial malleolus and in the other the medial deltoid ligament had been partially or completely ruptured.

Of 66 patients treated operatively between 1993 and 1997, 36 were available for follow-up. Arthroscopy had been performed in all patients pre-operatively to assess the extent of the intra-articular lesions. The American Orthopaedic Foot and Ankle Society hind-foot score was used for clinical evaluation and showed a significant difference in both the total and the functional scores (p < 0.05), but not in those for pain or alignment, in favour of the group with a damaged deltoid ligament (p < 0.05). The only significant difference between the groups on the short-form 36 quality-of-life score was for bodily pain, again in favour of the group with a damaged deltoid ligament. There was no significant difference between the groups in the subjective visual analogue scores or in the modified Kannus radiological score.

Arthroscopically, there was a significant difference with an increased risk of loose bodies in the group with an intact deltoid ligament (p < 0.005), although there was no significant increased risk of deep cartilage lesions in the two groups.

At a mean follow-up of 13 years after operative treatment of a supination-external rotation type-4 ankle fracture patients with partial or complete rupture of the medial deltoid ligament tended to have a better result than those with a medial malleolar fracture.
