Bone turnover markers are risk factors for endplate injuries during lumbar interbody fusion: a retrospective case-control study.

Background: Intraoperative endplate injury (IEI) is a type of fracture and a potential complication during lumbar interbody fusion (LIF). Osteoporosis diagnosed by bone mineral density (BMD) is a well-known risk factor for fracture itself and IEI also. The bone turnover markers (BTMs) are parameters of bone qualities and have some correlations with fractures, but there is no study about the BTMs and intraoperative fractures especially IEI.

A new 3D full-body scanner analyzing the sagittal and coronal balance of the adult spine: a preliminary prospective observational study.

Background: The degenerative spondylosis can cause the difficulty in maintaining sagittal and coronal alignment of spine, and X-ray parameters are the gold standard to analyze the malalignment. This study aimed to develop a new 3D full body scanner to analyze the spinal balance and compare it to X-ray parameters.

Methods: Ninety-seven adult participants who suffer degenerative spondylosis underwent 3D full body scanning, whole spine X-rays, clinical questionnaires and body composition analyses.

Intra-Articular Injections of Hyaluronic Acid or Steroids Associated With Better Outcomes Than Platelet-Rich Plasma, Adipose Mesenchymal Stromal Cells, or Placebo in Knee Osteoarthritis: A Network Meta-analysis.

Purpose: To evaluate the clinical effects of hyaluronic acid (HA), steroids, platelet-rich plasma (PRP), or adipose mesenchymal stromal cell (MSC) injections in the treatment of knee osteoarthritis (OA).

Methods: Randomized controlled trials with OA of the knee that compared HA, steroids, PRP, adipose MSC, or their combination with placebo or in head-to-head combination were identified from the MEDLINE, EMBASE, Cochrane Library, Web of Science, and SCOPUS databases up to June 30, 2019. We performed a network meta-analysis of the relevant literature to determine whether there was benefit from HA, steroids, PRP, or adipose MSC treatment as compared with placebo.

Comparison of femoral tunnel length and obliquity of anatomic versus nonanatomic anterior cruciate ligament reconstruction: A meta-analysis.

Purpose: Theoretical considerations suggest that femoral tunnel length might cause graft mismatch, and femoral tunnel obliquity could be related to the longevity of graft in anterior cruciate ligament (ACL) reconstruction. However, controversy still exists regarding these issues in the context of the comparison of anatomic and nonanatomic ACL reconstructions. The purpose of this meta-analysis was to compare the length and obliquity of the femoral tunnel created by drilling through either anatomic or nonanatomic ACL reconstructions.

Better clinical outcomes after unicompartmental knee arthroplasty when comparing with high tibial osteotomy.

Background: Both high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are well-established treatments for medial knee osteoarthritis (OA). However, it is unclear whether HTO or UKA leads to better clinical outcomes and lower complication rates. This meta-analysis compared the clinical outcomes and complications of HTO and UKA in patients with medial knee OA.

Correction to: Use of autogenous onlay bone graft for uncontained tibial bone defects in primary total knee arthroplasty.

After the publication of this article [1] it came to the attention of the authors that there were 2 errors in the results section: 0.0.856 should be 0.

Use of autogenous onlay bone graft for uncontained tibial bone defects in primary total knee arthroplasty.

Background: The use of autogenous bone graft is a well-known technique for reconstruction of tibial bone defects in primary total knee arthroplasty (TKA). In cases where the size of the bone graft is inappropriate, the stability of bone graft fixation and subsequent bone graft to host bone incorporation may be compromised. We describe a simple and reliable technique of reconstruction in a proximal tibia bone defect at the time of primary TKA by using autogenous onlay bone graft (AOBG).
