This novel technique could help athletes suffering from chronic groin pain return to play more quickly, both facilitating and allowing deferral of remedial physiotherapy treatments, and potentially avoiding the need for surgery.

Ultrasound guided alcohol ablation for the treatment of Morton's neuroma was a safe procedure that significantly reduced pain and may offer an alternative therapy to surgery.

PURPOSE. To evaluate the correlation between trochlear dysplasia and anterior cruciate ligament (ACL) injury METHODS. Magnetic resonance images (MRIs) of 95 knees in 54 males and 36 females aged 4 to 74 (mean, 28) years who had anterior knee pain and suspected ligamentous injury were reviewed. The MRIs were independently reviewed by 2 musculoskeletal radiologists on 2 occasions. According to the Dejour classification, trochlear dysplasia was classified into types A, B, C, and D. Intra-articular injuries/ disorders of the patients included patellofemoral osteoarthritis, chondromalacia patella, meniscal tears, and ligamentous injuries. Intra- and inter-observer variability was calculated. RESULTS. 58 of the knees had trochlear dysplasia, 38 of which were Dejour type A. The intra- and inter-observer variability was good to excellent (Kappa=0.76-1). ACL tear was the most common injury (n=13). No ACL injury occurred in patients without trochlear dysplasia. The odds of having sustained an ACL injury were 8.8 fold greater in Dejour type-A knees than in non-type-A knees (p=0.023). CONCLUSION. Dejour type-A trochlear dysplasia was associated with ACL injuries.

Access to sonographers and sonologists is limited in many communities around the world. Telerobotic sonography (robotic ultrasound) is a new technology to increase access to sonography, providing sonographers and sonologists the ability to manipulate an ultrasound probe from a distant location and remotely perform ultrasound examinations. This narrative review discusses the development of telerobotic ultrasound systems, clinical studies evaluating the feasibility and diagnostic accuracy of telerobotic sonography, and emerging use of telerobotic sonography in clinical settings. Telerobotic sonography provides an opportunity to provide real‐time ultrasound examinations to underserviced rural and remote communities to increase equity in the delivery of diagnostic imaging.

Predicting postoperative outcomes following total knee arthroplasty (TKA) is important for patient selection. This study focuses on patient-reported outcomes and satisfaction in relation to preoperative radiographic arthritis severity. A retrospective chart review of 420 TKAs was performed. Patient satisfaction was determined using a structured telephone survey with questions focused on degree of satisfaction whether they would have surgery again and their ability to kneel. The radiographic severity of the arthritis of the tibiofemoral joint was graded by a musculoskeletal radiologist using the Kellgren–Lawrence grading scale. The patellofemoral compartment was graded using the scale described by Jones et al. Those grouped as severe arthritis had an overall satisfaction rate of 96% (76% fully satisfied and 20% partially satisfied) compared with 82% of the time (64% fully satisfied and 18% partially satisfied) if their arthritis was mild. Postoperatively 51% of TKA patients were able to kneel. Univariate logistic regression showed an association between higher rates of satisfaction and male gender (p = 0.053), severity of preoperative radiographic arthritis (p = 0.034) those who would have surgery again (p ≤ 0.0001) and those able to kneel (p = 0.005). Patients should be informed preoperatively that if their arthritis is only mild radiographically, their outcomes are less predictable. There should also be a discussion surrounding kneeling and activities patients do, which may require kneeling, as many are unable to kneel postoperatively. The Level of Evidence for the study is III.

Introduction: This study aimed to develop a risk stratification model to differentiate benign and malignant MRI-imaged musculoskeletal soft-tissue tumours, informing decisions surrounding biopsy and follow-up imaging. Methods: Imaging of patients who underwent MRI and subsequent biopsy to evaluate a soft-tissue mass was retrospectively reviewed. Features analysed included patient age; tumour size; shape; margins; enhancement pattern; signal intensity pattern; deep fascia, neurovascular bundle, bone and joint involvement; and the presence of necrosis, haemorrhage, oedema and intralesional fat. Univariate comparisons, by final histopathological status, employed t-tests and chi-square tests, followed by simple and multiple logistic regressions. Variables included in the final multiple regression model were used to define a three-level risk stratification strategy. Results: One-hundred and ten patients were included in the analysis. Univariate relationships were identified between malignancy and age, tumour size, deep fascia involvement, neurovascular involvement, necrosis, haemorrhage, oedema and heterogeneous enhancement (all P < 0.01). Final multiple regression modelling included size, enhancement and oedema. Thirty of 40 (75%) tumours >5 cm with surrounding oedema ('high risk') were malignant, 13 of 47 (28%) tumours with one or more of tumour size >5 cm, surrounding oedema or heterogeneous enhancement ('moderate risk') were malignant, and none of the 16 tumours ≤5 cm with the absence of surrounding oedema and heterogeneous enhancement ('low risk') were malignant. Conclusions: A model including tumour size, enhancement and oedema has potential to stratify soft-tissue tumours into high-, intermediate-and low-risk categories; this may inform decisions surrounding biopsy and follow-up imaging.

Our protocols for disinfecting nonendocavity and endocavity probes are compliant with sonography guidelines and general disinfecting guidelines. Although limited by a small sample size, our study showed that our protocol for disinfecting endocavity probes seems adequate. With a 25.9% bacterial contamination rate for nonendocavity probes, the adequacy of our protocol for disinfecting nonendocavity probes is more debatable; however, this bacterial contamination rate is at the lower end of the values reported in the literature. With the use of an effective disinfectant, education of sonographers, and implemented changes, we hope to decrease bacterial contamination rates and thus decrease the potential for bacterial transmission.

Sonography is a useful tool for imaging the lateral abdominal musculature in patients with side strain, which occurs as a result of tearing of the internal oblique muscle from the lower four ribs or costal cartilage. Sonographic findings can be used to confirm the diagnosis, localize the site, and assess the characteristics of a tear.
