Purpose: The aim of the present study was to assess outcomes of using the push-through total femoral prothesis (PTTF) for revision total hip replacement with extreme bone loss.

Methods: 10 consecutive patients who received PTTF between 2012 and 2018 for revision hip arthroplasty were included in the study. Primary functional outcomes were assessed using Harris Hip Score (HHS), Toronto Extremity Salvage Score (TESS) and Musculoskeletal Tumor Society (MSTS) scores.

Early results of a novel modular knee arthrodesis implant after uncontrolled periprosthetic knee joint infection.

Aim: The aim of this study is to evaluate the functional outcomes and complications after non-fusion knee arthrodesis with a modular segmental intramedullary implant used for infected total knee arthroplasty revisions.

Methods: A retrospective review of the patients who had been surgically treated with a modular intramedullary arthrodesis implant for recurrent infection after revision TKA between January 2016 and February 2020 were included. The indications for arthrodesis were failed infected TKA with massive bone loss, deficient extensor mechanism and poor soft tissue coverage that precluded joint reconstruction with revision TKA implants.

Joint awareness after fixed and mobile-bearing total knee arthroplasty with minimum 12 years of follow-up: A propensity matched-pair analysis.

Background: Many comparative articles studied mobile-bearing (MB) and fixed-bearing (FB) total knee arthroplasties (TKAs). Meta-analyses found no difference in survival or biomechanical outcome. This study aimed to compare long-term clinical results between fixed-bearing (FB) and mobile-bearing (MB) total knee arthroplasty (TKA) as well as patients' adaptation to their artificial joints.

Low dose vancomycin-loaded spacers for two-stage revision knee arthroplasty: High success, low toxicity.

Background: Two-stage revision arthroplasty is a widely used treatment method for infected knee arthroplasty. Loading high doses of antibiotics to spacer during the first stage is standard practice. However, there are reported systemic side effects attributed to antibiotic-loaded spacers.

Postoperative bleeding adversely affects total knee arthroplasty outcomes in hemophilia.

Background: Hemophilic arthropathy can result in severe degenerative arthritis and functional limitations in the knees of relatively young patients. Total knee arthroplasty (TKA) provides pain relief and gain of function in advanced-stage hemophilic arthropathy cases. However, little is known about the long-term effects of early major postoperative bleeding (MPOB) in people with hemophilia (PWH).

In the first stage, following removal of the prosthesis and debridement, a spacer consisting of 1 g of vancomycin per 40 g of cement was placed in the infected joint space.

Sagittal spinal alignment after total hip arthroplasty for neglected high hip dysplasia: does changing the distorted mechanics of the hip normalize spinal alignment?

Purpose: The false acetabulum lies more laterally and posteriorly compared with the true acetabulum. Spatial orientation of the pelvis is significantly altered in patients with neglected high hip dysplasia. There has been no study to investigate how pelvic or sagittal spinal alignment change after true acetabulum gains function with hip arthroplasty.

Functional results in periacetabular osteotomy: is it possible to obtain a normal gait after the surgery?

Introduction: Gait analysis is one of the poorly understood dimensions of the functional results obtained after periacetabular osteotomy (PAO) due to dysplasia of the hip.

Materials And Methods: Spatiotemporal parameters as well as coronal and sagittal plane kinematics and moments were compared among three demographically similar groups of subjects: (i) 23 patients with excellent results according to the Harris Hip Score (HHS) (mean 6.6 years of follow-up); (ii) 12 patients with good and fair results according to the HHS (mean 9.

Does kinesiophobia affect the early functional outcomes following total knee arthroplasty?

The purpose of this study was to investigate the effects of kinesiophobia on early functional outcomes in patients following total knee arthroplasty (TKA) and how kinesiophobia is related to functional outcomes and pain. The Tampa Scale for Kinesiophobia (TSK), 2-minute walk test (2-MWT), and the timed up and go test (TUG) were used to assess 46 TKA patients on discharge day. The pain levels and active knee flexion range of motion (ROM) were recorded.

Design: Retrospective cohort study.

Setting: A university hospital.

Transverse sacral fractures and concomitant late-diagnosed cauda equina syndrome.

Transverse sacral fractures in young patients occur with high-energy mechanisms. Because of the drawbacks in radiographic and neurologic evaluations of the sacral area in polytrauma patients, misdiagnosis is quite common. In this study, we aimed to report our clinical results in three patients with displaced transverse sacral fractures compromising the sacral canal and concomitant late-diagnosed (at least 48 hours) cauda equina syndrome.
