How does the Patel-Dhillon Classification help orthopedic surgeons?

The classification provides a detailed framework for surgeons to analyze the anatomical and mechanical aspects of various ankle malunion patterns, assisting them in selecting the optimal corrective procedures.

What is the significance of the Patel-Dhillon Classification?

The classification represents an important step toward restoring both form and function in patients with ankle malunions, promoting joint preservation over traditional ankle fusion.

PGI Surgeon's Innovative Ankle Malunion Classification Aids Joint Preservation

In November 2025, Dr. Sandeep Patel, an Associate Professor of Orthopaedics at PGI in Chandigarh, has made a significant breakthrough in the management of ankle malunions. He has developed a new classification system, the Patel-Dhillon Classification, which provides a detailed framework for assessing and treating these complex deformities.

Ankle malunions occur when ankle fractures heal in an improper position, often due to neglect or inadequate fixation. These conditions can lead to pain, instability, and arthritis if not addressed appropriately. Traditionally, such cases were managed with ankle fusion, sacrificing joint motion to relieve pain. However, recent advancements in orthopedic reconstruction have introduced joint-preserving corrective osteotomies as viable options for select patients.
