Background: Acetabular revision with extra-large (jumbo) cementless cups is an effective treatment for many cavitary and segmental peripheral bone defects. However, hip center elevation may occur with the use of a jumbo cup owing to the superior direction of reaming and the increased diameter of the component compared with the native acetabulum. Purposes: The primary goal of this study was to evaluate the radiographically observed hip center elevation with the use of jumbo cups in acetabular and total hip revision at our institution. Materials and methods: We retrospectively reviewed control radiographic images of 43 consecutive patients treated with acetabular and total hip revision arthroplasty with a press-fit cementless cup. The difference between the height of the rotation center of the acetabular cup and the height of the rotation center of the contralateral native hip relative to the inter teardrop line was radiographically measured. Results: The radiographically measured mean elevation of the rotation center of the jumbo cup was 8,75 mm, which yielded an average increase in the height of the rotation centre of 83,6. A mean vertical shift of the rotation center of 0,72 mm was estimated for every 1 mm increase in the size of the jumbo cup. Conclusions: Our results indicate that the use of jumbo cups in revision hip arthroplasty leads to elevation of the rotation center of the hip with an average of 9 mm. This could be considered by the surgeon in an attempt to restore leg length, stability and biomechanics of the prosthetic hip.

Purpose: to assess the recovery of static, dynamic balance and postural control while overcoming muscle imbalance after an anterior cruciate ligament reconstruction by applying analytical exercises. Material and methods: Material: 15 men (mean age 25.16) were observed in the span of 14 weeks (three and a half months) after anterior cruciate ligament reconstruction. They underwent physiotherapy, including analytical kinetic chain exercises in hospital, ambulatory and at home conditions. Research, measurement, and evaluation methods include range of motion in the knee joint, manual muscle testing (MMT), static and dynamic balance tests, and postural control tests. Statistical methods include statistical data grouping, Cronbach’s test, descriptive method, testing of statistical hypotheses, and correlation analysis. The data was processed with SPSS v.24.0 for Windows. Results: The results show a change in the static postural control with a 1/4-point deviation from the standard. This requires the inclusion of additional sensorimotor exercises in combination with other specific and general strengthening exercises. Conclusion: From the performed observation and the obtained results, compared to those of 20 healthy men, the following conclusion has been drawn: the analytical exercises for lower extremities lead to the overcoming of dysfunction and increased stability in the extremities. The physiotherapy programme should include sensory stimulation exercises tailored for strengthening the weakened muscles and should contribute to the overcoming of muscle imbalance.

The aim of the following article is to present the role of multidisciplinary team in the implementation of integrated care for patients scheduled for surgical treatment of osteoarthritis. It can include different professionals from health care and social sectors depending on patients` needs. Integrated provision of care is connected to a system evaluation of every aspect of the health status of the patient by different health care professionals and team planning of the procedures needed for the patient. Care provided by multidisciplinary team help for the improvement of activity after surgical intervention, functional abilities, psychological and social health
