Use of contact pressure-sensitive surfaces as an indicator of graft tension in medial patellofemoral ligament reconstruction.
No previous description has been made about an objective method to test the graft resistance in MPFL reconstruction intraoperatively. In our study, we aimed to obtain intraoperative objective data about the graft resistance using contact pressure-sensitive surfaces and measuring pressure formed under the graft. ⋯ Contact pressure-sensitive surfaces provided objective data when placed under the graft in natural MPFL and during surgery. Therefore, they may be used as an objective marker providing information about graft resistance.

Subtrochanteric shortening osteotomy combined with cemented total hip arthroplasty for Crowe group IV hips.
Total hip arthroplasty (THA) is a challenging surgical procedure that can be used to treat severely dislocated hips. There are few reports regarding cemented THAs involving subtrochanteric shortening osteotomy (SSO), even though cemented THAs provide great advantages because the femur is generally hypoplastic with a narrow, deformed canal. ⋯ SSO combined with cemented THA is an effective treatment for severely dislocated hips. Leg lengthening is not necessarily associated with nerve injuries, and the likelihood of this surgical complication may be related to the presence of hip flexion contracture.

Comparative StudyClinical comparison between double-row and transosseous-equivalent repairs for medium to large size rotator cuff tears.
The transosseous-equivalent (TOE) repair of the rotator cuff tears was invented to make up for several shortcomings of the double-row (DR) repair. However, no studies have compared the clinical aspects of the DR repair and the TOE technique, supporting the superior results of the TOE technique over the DR repair, including the benefit of minimizing surgical steps. We asked whether differences existed between the two repairs regarding clinical outcomes, time and costs. ⋯ This study failed to demonstrate clinical differences between the techniques. However, when stratifying rotator cuff tears according to the tear sizes, significant differences were found in operative time and cost: the DR repair had the advantage of cost effectiveness by saving anchors for the lateral row, while the TOE repair required less operative time with more anchors used for the lateral row in the large size tears. This finding provides evidence to support the use of the TOE repair to reduce surgical steps.

Feasibility study on the potential of a spiral blade in osteoporotic distal femur fracture fixation.
Osteoporotic fractures of the distal femur (primary as well as periprosthetic) are a growing problem in today's trauma and orthopaedic surgery. Therefore, this feasibility study should identify the biomechanical potential of a (commercially available) spiral blade in the distal femur as compared to a single screw without any additional plate fixation. Additionally, the influence of cement augmentation was investigated. ⋯ The investigated spiral blade was mechanically superior, significantly, as compared to a screw in the distal femur. These results back up the further development of a distal femoral blade with spiral blade fixation for the treatment of osteoporotic distal femur fractures.

Clinical and radiographical results after double flip button stabilization of acute grade III and IV acromioclavicular joint separations.
Persistent horizontal instability after acute acromioclavicular (AC) joint separation may provoke unsatisfactory results of conservative treatment. ⋯ IV.
