Abstract

Abstract Purpose The topic of elective implant removal (IR) in healed fractures of the lower extremity remains controversial, particularly when unspecific symptoms of discomfort, which cannot be quantified, are the primary indication. This study aims to assess indications and outcomes of elective IR of the lower extremity, focusing on unspecific symptoms of discomfort and patient satisfaction postoperatively. Materials and methods The retrospective cohort study was conducted at a single level I academic trauma center. We included patients who underwent elective IR for healed fractures of the ankle, foot, patella, and proximal tibia from 2016 to 2021. All patients were followed-up for a minimum of 6 weeks after IR. Our outcomes of interest were patient satisfaction, complications, and alleviation of complaints. Results A total of 167 patients were included in the study. Unspecific symptoms of discomfort were the most common reason for IR in all investigated anatomical regions of the lower extremity (47.9%), followed by pain (43.1%) and limited range of motion (4.2%). 4.8% of patients experienced a combination of pain and range of motion limitation. Among all patients, 47.9% reported subjective improvement after IR. IRs based on unspecific symptoms of discomfort were significantly less likely to show alleviation of complaints after IR (27.5%, OR 0.19, p ≤ 0.01). Patients who reported limited range of motion (OR 1.7, p = 0.41) or pain (OR 6.0, p = 0) were significantly more likely to be satisfied after IR. Patients who reported sensitivity to cold weather also showed a decrease of complaints after IR (OR 3.6, p = 0.03). Major complications occurred in 2.1% of cases. The minor complication rate was 8.4% (predominantly impaired wound healing). Smoking patients showed a significantly higher risk of complications after IR (OR 5.2, p = 0.006). Persistent pain postoperatively was detected in 14.7%. Conclusion When elective IR for consolidated fractures of the lower extremity is primarily motivated by patients’ subjective symptoms of discomfort, the risk for postoperative dissatisfaction significantly increases. Objective symptoms on the other hand are associated with higher satisfaction after IR. While the procedure is generally safe, minor complications such as wound healing disorders can occur, especially in smokers. Patient education and well-documented informed consent are critical.
