Review Meta AnalysisGap balancing versus measured resection for primary total knee arthroplasty: a meta-analysis study.
To achieve the most desirable post-operative results, operation techniques and procedures for total knee arthroplasty (TKA) are highly standardized. However, debates persist whether patients having undergone a gap balancing technique (GB) perform better than those having undergone measured resection (MR) technique. Therefore, a meta-analysis study was conducted to investigate advantages of GB compared to the MR. The focus of the present study was on clinical and functional scores, radiological measurements and further complications. ⋯ GB and MR achieve similar outcomes for TKA. In the GB group, a proximalisation of the joint line and extended operating time was detected. Regarding the additional outcomes of interest, the present analysis showed comparability between both groups, MR and GB.

ReviewPatellar fixation graft via suture anchors versus tunnel techniques during isolated MPFL reconstruction for recurrent patellofemoral instability: a systematic review of the literature.
There is still a lack of evidence concerning the patellar fixation of the medial patellofemoral ligament (MPFL) graft in selected patient with recurrent instability. The purpose of the present study was to investigate and compare clinical outcomes and further complications of isolated MPFL reconstruction via suture anchors versus tunnel techniques for recurrent patellofemoral instability. ⋯ Both the suture anchors and the bone-tunnels are a feasible option for isolated MPFL reconstruction in patients with recurrent patellofemoral instability. Patellar fixation via suture anchors evidenced a reduced rate of anterior knee pain, revision surgeries, apprehension test and an overall reduced complication compared to the bone-tunnel technique.

Comparative StudyThe use of accelerometer-based navigation for coronal TKA alignment: a prospective, single surgeon comparative study.
There is the need for a device that can be used to accurately position components during total knee arthroplasty (TKA) with minimal impact on procedure time, workflow and cost. This study aimed to investigate the accuracy and time efficiency of a novel, accelerometer-based navigation system (ABN). ⋯ The use of the ABN system significantly improved accuracy of implant position and alignment without increasing surgical time.

Lumbar spinal fusion of low-grade degenerative spondylolisthesis (Meyerding grade I and II): Do reduction and correction of the radiological sagittal parameters correlate with better clinical outcome?
Lumbar and lumbosacral spinal fusion is an established procedure for the treatment of degenerative spondylolisthesis. However, the impact of reduction in the affected segment and of improvement in the radiological sagittal parameters on the clinical outcome remains unclear. Purpose of the study is to analyze the correlation between the radiological sagittal parameters and clinical outcome after lumbar spinal fusion in low-grade degenerative spondylolisthesis. ⋯ Reduction in anterior displacement of the affected segment in the surgical treatment of low-grade degenerative spondylolisthesis does not have an impact on the clinical outcome.

The etiology of revision total hip arthroplasty: current trends in a retrospective survey of 3450 cases.
Over the last years, the design of implants, the surgical approaches, and diagnostic tools changed in primary and revision of total hip arthroplasty. A knowledge of the different causes for revision after total hip arthroplasty is essential to avoid complications and failures. The purpose of this study was to determine trends of the etiology of implant failures over the last years by analyzing indications of revision hip arthroplasty. ⋯ This study successfully updated the current knowledge of different failure mechanisms in revision hip arthroplasties. The data proved that cup loosening was the most common failure mechanism in older patients, while in young patients, septic complications showed a high incidence. Probably, due to improved diagnostic tools, the percentage of infection in revision hip arthroplasty increased over the years.
