Data collection
We collected the following from each study using a data collection sheet and separated into each group: (1) basic data (author name, year of publication, journal name, study type, investigation period, number of patients, patient age, and tumor histology) and the range of resection, categorized by Malawer et al17. or Musculoskeletal Tumor Society (MSTS).; (2) postoperative functional outcome assessed using the MSTS score; the reconstruction; and (4) complications, as categorized by Henderson et al.

Methodological quality assessment
0-4, very low quality; 5-8, low quality; 9-12, moderate quality; 13-16, high quality20. 19-24, high quality. Disagreements were resolved through discussion between the authors (H.A., A.A., and C.E.).

Statistical analyzes
We performed a single-arm meta-analysis of the data from the selected studies. A random-effects or fixed-effect model was used to calculate the pooled incidences of implant failure rate 5 years after surgery and MSTS score. Summary effect measures are presented with their corresponding 95% confidence intervals (CI). Statistical heterogeneity was evaluated using the I2 statistic. indicated insignificant, low, moderate, and high levels of heterogeneity, respectively21. A random-effects model was used if I2>50%; otherwise, a fixed-effects model was used. Statistical analyzes were performed using Review Manager version 5.3 (The Cochrane Collaboration 2014, The Nordic Cochrane Centre, Copenhagen, Denmark). We calculated the standard deviation (SD) and standard error (SE) from the information in the articles or assumed these values from the range 22, and only data with SD or SE were included in the analysis. Statistical significance was set at p<0.05 for all analyzes.
