AI Article Synopsis
- Twenty-eight knees in 26 patients were studied for revision total knee arthroplasties (TKAs) due to major bone loss, categorized into three groups based on implant stability and bone loss severity.
- Outcomes assessed included pain levels, knee function (via KSCRS), and imaging results, showing significant improvements in pain, range of motion, and knee scores at an average of 48 months post-surgery (p<.05).
- A high success rate was observed, with 96% of knees showing clinical improvements and 86% demonstrating stable components and effective bone graft integration, suggesting that revision TKA can be successfully performed with various grafting techniques for serious osteolytic defects.
Article Abstract
Twenty-eight knees in 26 patients underwent revision TKA requiring surgical management of major osteolytic defects. Three groups of osteolytic defects were identified based upon the degree of implant stability and the magnitude of bone loss. Outcome measures included the Knee Society Clinical Rating Score (KSCRS), visual analog pain score, and radiographs. At a mean follow-up of 48 months, the average knee pain scores, range of motion, and KSCRS improved (p<.05). Ninety-six percent of the knees demonstrated clinical and functional improvement. Radiographs for 24 revision TKA's (86 percent) demonstrated component stability and incorporation of both cancellous and structural allografts. Revision TKA for major osteolytic defects may be effectively performed using a variety of bone grafting techniques. Both morselized and structural bone grafting, in combination with stemmed components was successful in managing revision TKA in the setting of major osteolysis. Significant improvement in clinical and radiographic outcomes may be anticipated using these surgical techniques.

Department of Nephrology, St. Georg Hospital, Leipzig, Germany.
Background: Malignant hypercalcemia is usually caused by osteolytic processes of metastases, production of parathormone-related peptide, or secretion of 1,25-dihydroxyvitamin D. Ectopic PTH (parathyroid hormone) production by malignancy is very unusual.
Methods: Case report and review of the literature.

Background: Accumulation of malignant plasma cells in the bone marrow causes lytic bone lesions in 80% of multiple myeloma patients. Frequently fracturing, they are challenging to treat surgically. Myeloma cells surviving treatment in the presumably protective environment of bone lesions impede their healing by continued impact on bone turnover and can explain regular progression of patients without detectable minimal residual disease (MRD).

Minimally invasive techniques for metastatic disease treatment in the periacetabular region of the pelvis have grown increasingly popular. Open surgical management of osteolytic lesions in the pelvis are associated with high perioperative complication rates that approach 30-36% and often require suspension of systemic treatment. Conservative measures, such as radiation treatment, can improve functional status in select patients while avoiding the morbidity of open surgical intervention; however, conservative measures do not address the problem of mechanical instability that can lead to pathologic fracture or loss of independence.

Cranioplasty to restore calvarial defects involves reconstruction with alloplastic materials or autologous tissues in order to provide the best protection to all intracranial contents. Sometimes, autologous bone may not be available; therefore, different materials have emerged such as polymethylmethacrylate plate, titanium mesh, and hydroxyapatite. However, when it is impossible to replace the autologous bone, the aesthetic result is generally unsatisfactory.

Study Design: Review of mesh-container plasty (MCP) in osteolytic vertebral metastases.
Objective: This study aims to assess the efficacy and safety of MCP in treating advanced vertebral metastases with posterior wall defects.
Background: Diagnosis of vertebral metastases typically relies on the patient's tumor history, bone scans, or vertebral MRI.
