Comparative StudySTT arthrodesis versus proximal row carpectomy for Lichtman stage IIIB Kienböck's disease: first results of an ongoing observational study.
Scapho-trapezial-trapezoidal (STT) arthrodesis and proximal row carpectomy (PRC) are used for the treatment of Lichtman stage IIIB Kienböck's disease. This study prospectively compares 1-year results of STT arthrodesis and PRC in Lichtman stage IIIB Kienböck's disease. ⋯ One year after operation, slightly better results were observed in patients with PRC compared to STT arthrodesis.

Functional outcome of limb salvage surgery with mega-endoprosthetic reconstruction for bone tumors.
The use of a mega-endoprosthesis has become the method of choice for reconstruction after bone tumors. In this study, we sought to determine the functional outcome and complications associated with mega-endoprosthesis. ⋯ Mega-endoprosthetic reconstruction in limb salvage provides good functional outcome in patients with bone tumors.

Effect of depressive symptoms on perceived disability in patients with chronic shoulder pain.
Psychological distress may be an important determinant of perceived disability in patients with chronic musculoskeletal disorders. We evaluated the relationship between depressive symptoms and perceived disability in patients with chronic shoulder pain and quantified the contribution made by depression to perceived disability. ⋯ Level 2, prospective cohort study, prognostic study.

Viscoelastic adaptation of tendon graft material to compression: biomechanical quantification of graft preconditioning.
The tensile viscoelastic behaviour of tendon tissue is of central biomechanical importance and well examined. However, the viscoelastic tendon adaptation to external compression, such as when a tendon graft is fixated with an interference screw, has not been investigated before. Here, we quantify this adaptive behaviour in order to develop a new method to mechanically precondition tendon grafts and to better understand volumetric changes of tendinous tissue. The hypothesis of this study was that under compressive loads, tendon grafts will undergo a temporary volumetric (and therefore diametric) reduction, due to the extrusion of water from the tendon. ⋯ The viscoelastic behaviour of hamstring tendon grafts under pressure allows preconditioning of the grafts for reduction of volume and diameter and therefore to drill a smaller bone tunnel, retaining more of the original bone. At the same time, the collagen content of the transplant is preserved and a tight fit of the transplant in the bone tunnel achieved.

Review Comparative StudyA systematic review of randomized controlled clinical trials comparing hamstring autografts versus bone-patellar tendon-bone autografts for the reconstruction of the anterior cruciate ligament.
Controversies exist over which type of graft is best for the reconstruction of the anterior cruciate ligament (ACL). The purpose of this systematic review was to evaluate the effectiveness of ACL reconstruction using either hamstring (HT) autografts or bone-patellar tendon-bone (BPTB) autografts. ⋯ ACL reconstruction with HT autografts or BPTB autografts achieved similar postoperative effects in terms of restoring knee joint function. HT autografts were inferior to BPTB autografts for restoring knee joint stability, but were associated with fewer postoperative complications.
