Implant-free anterior cruciate ligament (ACL) reconstruction is the fixation of ACL grafts without the need for artificial implants. Our aim was to study the evolution of this technique, review the biomechanical evidence and summarise the results. ⋯ Various biomechanical studies have reported that by adhering to certain technical details, this technique provides comparable fixation strength as conventional ACL fixation. The outcome studies of implant-free ACL reconstruction also report clinical results similar to ACL reconstruction with conventional implants.

Locking plate as a definitive external fixator for treating tibial fractures with compromised soft tissue envelop.
Tibial fractures with compromised soft tissue envelop may lead to significant complications. The optimal management of these injuries remains controversial. Recently, locking plate used as a definitive external fixator is attractive because it not only minimizes trauma to the soft tissues, but also overcomes the shortcomings of standard external fixators. The objective of this study was to evaluate the outcome of using locking plate as a definitive external fixator for treating tibial fractures with compromised soft tissue envelop. ⋯ The locking plate used as a definitive external fixator provided a high rate of union. The patients experienced a comfortable clinical course, excellent knee and ankle joint motion, satisfactory functional results and an acceptable complication rate. However, the stiffness of external locked plating is not clear, therefore, clinical recommendation on its practical use to reduce the risk of implant failure still need to be determined.

Comparative StudyThe clinical and radiographic results of intertrochanteric curved varus osteotomy for idiopathic osteonecrosis of the femoral head.
In this study, postoperative results of intertrochanteric curved varus osteotomy (CVO) for idiopathic osteonecrosis of the femoral head (ION) were studied retrospectively and optimal indication of CVO was considered. ⋯ The results of CVO for ION were successful, if this procedure was indicated for cases with intact load-bearing area more than 40 %.

An economic analysis of aseptic revision hip arthroplasty: calculation of partial hospital costs in relation to reimbursement.
Aseptic loosening is one of the most common intermediate and long-term complications after total hip replacement (THR). These complications cause suffering and require expensive revision surgery. Little concrete data on direct costs are available from the hospital's, moreover operating department's perspective. We here provide a detailed analysis of the costs of THR revision and relate them to reimbursement underlying the German diagnosis-related groups (DRG) system. ⋯ Our study for the first time provides a detailed analysis of the major direct case costs of THR revision for aseptic loosening from the provider's perspective. Our findings suggest that these revision operations could be performed cost-beneficially by the operating unit. From an economic perspective, cases with higher cost weights are more favorable for a hospital. These results need to be confirmed in multicenter studies.

Can cantilever transforaminal lumbar interbody fusion (C-TLIF) maintain segmental lordosis for degenerative spondylolisthesis on a long-term basis?
To determine if cantilever transforaminal lumbar interbody fusion (C-TLIF) using the crescent-shaped titanium interbody spacer (IBS) favors acquisition of segmental and lumbar lordosis even for degenerative spondylolisthesis (DS) on a long-term basis. ⋯ Despite the inherent limitation of placing the IBS against the anterior endplate of the upper vertebra in the presence of DS, the C-TLIF helped significantly restore segmental as well as lumbar lordosis on a long-term basis, which would be of benefit in preventing hypolordosis-induced back pain and the adjacent level disc disease.
