Objective: this study aimed to evaluate the fixation of the trabecular metal wedge in patients undergoing revision of total hip arthroplasty.
Methods: twenty-three cases with minimum grading of Paprosky II-B that were operated between July 2008 and February 2013 were evaluated. These cases were evaluated based on radiographs before the operation, immediately after the operation and later on after the operation. Loss of fixation was defined as a change in the abduction angle of the component greater than 10° or any mobilization greater than 6 mm.
Results: it was found that there was 100% fixation of the acetabula after a mean of 29.5 months. One case underwent removal of the implanted components due to infection.
Conclusions: there is still no consensus regarding the best option for reconstructing hips with bone loss. However, revision using a trabecular metal wedge has presented excellent short- and medium-term results. This qualifies it as an important tool for achieving a fixed and stable acetabular component.

Background: Indications for primary total knee arthroplasty (TKA) have become more inclusive of morbidly obese patients, however, higher rates of complications and lower implant survival have also been reported in this population. The purpose of this study was to investigate the mid-term survival, clinical, and radiographic outcomes of a cementless trabecular metal monoblock tibial component in severely obese patients.
Methods: This was a retrospective study of class II and III obese (BMI > 35) patients who received a cementless primary TKA.
Trabecular metal collars in endoprosthetic replacements: do they osseointegrate?

Aims: Limb salvage surgery (LSS) is the primary treatment option for primary bone malignancy. It involves the removal of bone and tissue, followed by reconstruction with endoprosthetic replacements (EPRs) to prevent amputation. Trabecular metal (TM) collars have been developed to encourage bone ingrowth (osseointegration (OI)) into EPRs.

In recent years, additively manufactured metallic scaffolds have generated significant interest among researchers working in the field of bone tissue engineering and orthopaedic implants. Although such intricate, porous architectures are promising as bone substitutes, they need to be thoroughly tested for structural robustness as well as their capacity for bony integration. In this present work, we introduced and preclinically evaluated the biomechanical viability of Weaire-Phelan (WP) Ti-alloy scaffolds as bone replacement components.

Article Synopsis
- * The issues were caused by brownish pigments accumulating in the eye, likely moving from the trabecular meshwork through a previous surgical opening, despite conservative treatments like topical steroids not providing relief.
- * A successful follow-up procedure using a special laser technique helped to disperse the pigments and relieve the patient's symptoms, highlighting the need for awareness and management of this complication, as well as suggesting a preventative measure.
Comparing Trabecular Metal Versus Fiber Mesh Cementless Acetabular Components: A Single-Center Study of 6,563 Hips.

Background: Trabecular metal is being increasingly used in primary total hip arthroplasty (THA). This study compared medium-term (< 15 years) outcomes of fiber mesh titanium and trabecular metal acetabular components.
Methods: This study included 6,563 patients who underwent primary THA with either fiber mesh titanium or trabecular metal-backed acetabular components.
