Background Staff training in Active Support is designed to enable direct support staff to increase the engagement and participation of people with intellectual disabilities in a range of daily activities. Method Residents (n = 41) and staff of nine group homes participated. The effectiveness of Active Support was evaluated with a pre-test:post-test design, using a number of standardized assessments and other questionnaires, with group home staff as informants. These assessments were conducted before Active Support training and an average of 6.5 months later. Results Following implementation of Active Support residents experienced significant increases in domestic participation and adaptive behaviour. There were significant decreases in internalized challenging behaviour, overall challenging behaviour and depression. There was no significant pre-post change in other forms of challenging behaviour. Conclusions Our findings confirm and extend previous Active Support research showing that implementation of Active Support is followed by increased resident participation in activities. The significant improvements in adaptive behaviour, challenging behaviour and depression are of particular interest as the present study is among the first to report such effects. The study's limitations are discussed.

Purpose To compare gap displacement at various intervals of cyclic testing and biomechanical load to failure of a Krackow patellar tendon repair augmented with high-strength suture tape versus the standard Krackow transosseous technique for inferior pole patellar tendon rupture. Methods Twelve matched pairs of cadaveric knees were used (8 males and 4 females; mean age 79.6 years, range 57 to 96). An inferior pole patellar tendon rupture was simulated after random assignment of specimens in each pair to the standard or augmented Krackow technique. Each specimen was then repetitively cycled from 90° to 5° for 1,000 cycles. A differential variable reluctance transducer was used to measure gap displacement. After cyclic loading, load to failure was determined by pulling the tendon at a rate of 15 mm/s until a sudden decrease in load occurred. Results Compared with the control repair, specimens with augmented repair demonstrated significantly less displacement at all testing intervals up to 1,000 cycles ( P < .05). Two patellar tendons failed before the end of cyclic loading, and 4 specimens had inadequate tendon length for loading. Among the 18 remaining specimens, no significant difference in load to failure was observed between the experimental group (n = 11) and the control group (n = 7) (1,006.5 ± 332.1 versus 932.8 ± 229.1 N, respectively; P = .567). Conclusions Significantly greater gap displacement was observed in the standard Krackow repair group compared with the augmented Krackow group at all cyclic loading intervals. This suggests that the Krackow transosseous procedure augmented with high-strength suture tape is biomechanically viable for inferior pole patellar tendon repair. Clinical Relevance This biomechanical study supports the use of high-strength suture tape augmentation of Krackow transosseous repair for inferior pole patellar tendon rupture.

Venous thromboembolism (VTE) is a common complication after total hip arthroplasty (THA) and total knee arthroplasty (TKA), occurring in up to 85% of patients who are not treated with prophylaxis. The initiation of VTE development may occur intraoperatively. This study investigated whether this gap in VTE prophylaxis can be addressed by the use of intraoperative intermittent pneumatic compression devices (IPCDs) and if intraoperative IPCDs have a meaningful benefit in preventing symptomatic VTE. The authors defined symptomatic VTE as deep venous thrombosis in either lower extremity or a pulmonary embolism. The authors evaluated the medical records of 3379 patients who underwent THA or TKA at their institution in 2014 and 2015. Effects of various factors, including age, sex, body mass index, and smoking status, were compared between these 2 cohorts. Patients who experienced a symptomatic VTE were also matched by age, sex, and procedure type with randomly selected controls. In the patient sample, 47 patients (1.4%) developed VTE. Forty (1.2%) of these patients underwent TKA, whereas 7 (0.2%) underwent THA. Venous thromboembolism occurred less frequently in patients who received intraoperative IPCDs (0.8%) than in patients who did not receive them (1.5%); however, this difference did not reach statistical significance. Total knee arthroplasty was associated with increased odds of VTE compared with THA, as was female sex. These results did not show a statistically significant benefit to the intraoperative use of IPCDs. Pneumatic compression remains a fast, easy, low-cost, low-risk, intuitive intervention that can supplement the postoperative multimodal approach and is worthy of further study. Intraoperative IPCD use should be considered for patients with a higher risk of VTE. [Orthopedics. 2018; 41(1):e98-e103.].

Medial collateral ligament (MCL) injuries are the most common ligamentous injury of the knee. The extent of injury can range from a minor first-degree (1-degree) sprain to an extensive third-degree (3-degree) sprain that can propagate across the knee, rupturing one or both cruciate ligaments, and result in a knee subluxation or dislocation. A common pattern involves the combined anterior cruciate ligament (ACL) and MCL injury that is the focus of this chapter. The vast majority of these combined medial-sided injuries are treated nonoperatively with delayed reconstruction of the ACL injury in athletically active individuals. The MCL and associated medial structures are carefully assessed on physical examination, and classification of injury is based upon abnormal limits of joint motion. In vitro cadaveric biomechanical testing has given us a better understanding of ligament deficiency and altered joint motion. Consistency in terminology is necessary for proper classification of injury and reproducible categorization of injury patterns to be able to compare both nonoperative and operative treatment of various injury patterns.
