Introduction: Total hip arthroplasty (THA) is one of the most commonly performed procedures the last decades in the field of orthopaedics. However, there has been a subsequent increase in revision rates for various reasons with instability and aseptic loosening being the predominant ones. Revision surgeries pose many challenges to the treating orthopaedic surgeons as well as significant burdens on patients and on healthcare systems globally. After a revision procedure, in addition to the best possible functional outcomes, longer lifespan of the implants, the least possible bone loss and restoration of as much as possible of bone stock should also be of priority. Materials & Methods: A case series of 11 patients with aseptic loosening of the acetabular component having moderate-to-severe acetabular bone loss is presented. All patients were managed with a trabecular titanium cup-cage construct in conjunction with impaction of morselized allograft. Results: This study assessed 11 patients (mean age 67.9 years) with Paprosky 2B-3B acetabular defects undergoing revision surgery (mean follow-up: 54.6 months). Functional outcomes improved significantly, including Harris Hip Score (44.8% to 80.7%), HOOS-JR (49.9% to 70.4%), and Forgotten Joint Score (13.6% to 81.8%). VAS and EQ-5D-5L scores also showed marked improvement. Logistic regression found no significant impact of age, sex, or ASA score on outcomes (p = 0.6). These results demonstrate notable functional recovery post-surgery. Conclusions: Revision surgery for aseptic loosening of the acetabular component using a trabecular titanium cup-cage construct with morselized allograft demonstrates excellent functional improvement and patient satisfaction. The procedure is effective in managing moderate-to-severe acetabular bone loss (Paprosky 2B-3B), restoring function and quality of life. Despite the challenges associated with such revisions, these findings highlight the efficacy and reliability of this approach in addressing complex cases without being significantly influenced by patient demographics or preoperative risk factors.

Patellar management in primary total knee arthroplasty (TKA) remains one of the most debated and variable aspects of contemporary arthroplasty practice. Patellar resurfacing, non-resurfacing, and selective resurfacing each offer distinct advantages, but no universally superior strategy has emerged. Although global functional outcomes are generally comparable across techniques, differences persist in anterior knee pain, survivorship, patellofemoral degeneration, and the likelihood of secondary patellar procedures. This narrative review synthesizes current clinical, radiographic, biomechanical, and registry-based evidence to provide a comprehensive understanding of these differences. Patellar resurfacing tends to offer clearer benefits in patients with advanced patellofemoral osteoarthritis, significant preoperative symptoms, unfavorable patellar morphology, or implant designs that increase patellofemoral loading. Conversely, non-resurfacing remains a safe and effective option in patients with minimal patellofemoral disease and favorable anatomical characteristics. Selective resurfacing represents a patient-tailored compromise, though its effectiveness is currently limited by the absence of standardized selection criteria. The integration of evidence across multiple studies reinforces that patellar resurfacing should follow an individualized, indication-guided approach instead of routine application. It also proposes a structured framework that incorporates anatomical, radiographic, and implant-related factors to guide patellar management during primary TKA.

Introduction: Total hip arthroplasty (THA) is the gold standard treatment for end-stage hip osteoarthritis. The rise in primary THA incidence has led to a corresponding increase in THA revision rates. Revision surgeries are challenging and pose significant burdens on patients and on healthcare systems worldwide. The use of short stems as revision implants are considered “off-label” and the literature on this application is scarce. Our purpose is to present the results of a revision surgery using a short femoral prosthesis as well as a review of the current literature on this perspective. Case Report: A 64-year-old male patient suffered from aseptic loosening of the right THA that was revised with a type-3 short femoral prosthesis. Conclusion: Short femoral stems are a viable option for revision surgeries especially for young patients. Although there are many surgeons who would oppose to their usage in this setting, few would deny that their advantages outnumber their cons. Keywords: Hip arthroplasty, revision surgery, short stem, downsizing.

This case report highlights a rare occurrence of osteomalacia induced by hypophosphatemia secondary to ferric carboxymaltose (FCM) therapy in a patient with hereditary hemorrhagic telangiectasia (HHT, or Rendu‐Osler‐Weber syndrome). A 21‐year‐old man presented with left tibial pain without prior trauma, accompanied by severe hypophosphatemia, vitamin D deficiency, and elevated fibroblast growth factor 23 (FGF23) levels. Upon the full diagnostic imaging work‐up, F‐18‐FDG PET/CT majorly contributed to the differential diagnosis by excluding potential malignancy and verifying a stress fracture. Treatment included vitamin D supplementation and oral phosphorus replacement, along with discontinuation of ferric carboxymaltose (FCM) therapy. This case demonstrates the importance of vigilance for metabolic bone disease in patients undergoing FCM treatment, particularly those with predisposing conditions such as HHT, to prevent misdiagnosis and mitigate complications.
