Design outcomes

Primary

Measure	Time frame
retrospective data analysis with a longest observation period of up to 10 years in the presence of complete clinical and radiological data; Complication evaluation of postoperative complications such as soft tissue infections, revision surgery or bony malhealing; Comparison of functional results after patellar fractures treated with different osteosynthetics (plate vs. screws vs. tension band osteosynthesis) according to the neutral-zero method for the knee joint documented in the patient file	—
