Objectives
Narrative objectives1
To investigate the risk of postoperative function and complications in patients with short residual proximal femur after resection of a distal femoral bone tumor, we performed a systematic review of studies reporting functional results and complications in patients with short residual proximal femur after reconstruction of a distal femoral bone tumor with custom-made megaprosthesis, APC and CPS implant.

Key inclusion criteria
Only studies reporting functional results and complications regarding megaprosthetic reconstruction of distal femur with short residual proximal femur following resection of bone tumor were included.
Key exclusion criteria
(1) Studies in which reconstruction was performed in patients without short residual proximal femurs were excluded. Studies that performed reconstruction in patients with short residual proximal femurs and did not specify both functional results and complications were also excluded. (2) Only English- and Japanese-language literature was included, with no restriction on the year of publication.

Data collection and presentation
Two authors (ST and TM) independently selected the studies and extracted the data. In case of any disagreement, agreement was reached between the two or the third author was consulted. The following data were collected using the data collection sheet. (1) Basic data: author, year of publication, journal name, type of study, number of patients, age of patients, histology of tumor (2) Surgical indication, method of reconstruction, cement fixation, porous coating, time to full weight bearing, stem length of prosthesis, adjuvant chemotherapy, adjuvant radiotherapy, nonunion, aseptic loosening, implant breakage, fracture, infection, mechanical survival where the endpoint was set to implant removal for any reason, oncological outcome, Musculoskeletal Tumor Society (MSTS) score [19], postoperative follow-up period.
Data summary
Data extracted from the collected study data are summarized in Table 1 and 2. Table 3 summarized the time to full weight bearing, nonunion, aseptic loosening, implant breakage, fracture, infection, mechanical survival, MSTS score [19], and postoperative follow-up period for each reconstruction method (custom-made megaprosthesis, APC, and CPS implant). Because all the studies included in this review were non-randomized, data pooling (meta-analysis) was not appropriate, and thus, not performed.
Assessment of methodological quality
Two authors (ST and TM) independently assessed the quality of the included studies. When there was disagreement, agreement was reached between the two authors or by consulting a third author. Articles included in the final analysis were independently assessed according to the Risk of Bias Assessment tool for Non-randomized Studies (RoBANS tool) for assessing the quality of non-randomized studies in meta-studies [20].
