Patient-specific arthroplasty system

A patient-specific arthroplasty system comprising:

• a ligament balancing tool that transmits tension measurement signals, the ligament balancing tool including a pin positioning block comprising a pin positioning dial for setting an angular position of a plurality of pin hole guides in the pin positioning dial;
• a database comprising electronic data including preoperative data, the tension measurement signals from the ligament balancing tool, and postoperative data associated with a plurality of patients;
• a preoperative evaluation module that causes a computing device to receive electronic preoperative data for a given patient;
• an analysis engine that causes the computing device to:
• analyze the postoperative data from the database,
• receive the tension measurement signals and the preoperative data,
• generate tension profiles based on the tension measurement signals,
• and generate surgical recommendation electronic data based on the tension profiles, the electronic preoperative data of the given patient, and the analysis of the postoperative data from the database;
• and
• a pin positioning block data module that electronically receives the surgical recommendation electronic data and determines pin positioning block settings electronic data based on the surgical recommendation electronic data, the pin positioning block settings electronic data including a recommended pin positioning dial setting.
