Simple Summary: This study explored the long-term outcomes of patients who underwent hip replacement surgery following the removal of malignant tumors in the hip area. The main focus was to understand how well patients recovered in terms of physical function and quality of life. The study included 30 patients treated between 2010 and 2018, all of whom received interdisciplinary therapy, consisting of both systemic and surgical treatments. The follow-up period averaged a little over three years. The results showed that younger patients tended to have better physical function and overall quality of life after surgery. The study also revealed that complications like implant failure were relatively low, and no amputations were necessary. These findings suggest that this type of surgery, combined with comprehensive interdisciplinary care, can be a safe and effective option for managing hip tumors. Further research is needed to continue improving patient outcomes and tailoring treatments to individual needs. Introduction: Over the past few decades, tumor arthroplasty has evolved into an established therapeutic approach for addressing bone defects following tumor resection in the extremities. As the diagnosis has a significant impact on patients' lives, it is important to give clear expectations for functional recovery. Therefore, we investigated both the functional outcomes and the quality of life (QoL) after tumor arthroplasty for malignant hip tumors. Methods: This retrospective study included patients who had undergone resections of malignant hip tumors with consecutive modular hip arthroplasty between 2010 and 2018. Demographics, tumor entity, and complications stemming from both tumors and treatments were evaluated through the analysis of medical records and perioperative records. The assessment of functional outcomes was conducted with the following patient-reported outcome measures (PROMs): the Harris Hip Score (HHS), Musculoskeletal Tumor Society Score (MSTS), and the Short Form Survey 36 (SF-36). Furthermore, we performed subgroup analysis in two groups: one divided into survivors and non-survivors, as well as younger individuals (<57 years) and older individuals (>57 years). Results: A total of 30 patients were included in the study. At the time of follow-up, 19 patients were deceased. The average duration of follow-up was 3.2 (±2.51) years. The average age at the time of surgery was 60.3 (±15.20) years. Notably, there were no cases of amputation reported (0%). Five cases of implant failure were identified (16.67%). Among these, one was attributed to infection (3.3%), while four resulted from aseptic loosening (13.3%). In terms of functional outcomes, MSTS indicated good results (18 ± 7; range: 7–28; 60%), and the HHS demonstrated moderate outcomes (75.3%). Younger survivors (<57 years) exhibited notably superior results in terms of both the MSTS and physical functioning in the SF-36 (p = 0.03). Conclusion: In summary, this study shows declining tumor arthroplasty-related complications and satisfying functional outcomes as well as QoL. Noteworthy aspects include the relatively low rates of amputation and local tumor recurrences, which significantly favor the selection of appropriate therapeutic options. Moreover, the findings underscore the substantial impact of patients' age on overall functionality and engagement in daily activities. [ABSTRACT FROM AUTHOR]
