Summary of the proposed classification for Hoffa’s fracture along with its recommended treatment modality.
| Classification | Description | Proposed treatment | Approach |
|---|---|---|---|
| Type1 | Unicondylar with <2.5 cm fragment size | Anterior to posterior lag screws | Standard parapatellar approach (medial or lateral) |
| Type 2 | Unicondylar with >2.5 cm fragment size | Posterior to anterior lag screws | Swashbucker approach/Gerdy’s tubercle osteotomy for lateral condyle and subvastus approach for medial condyle |
| Type 3 | Comminuted fracture | Lag screws augmented with a buttress plate | Swashbucker approach/Gerdy’s tubercle osteotomy for lateral condyle and subvastus approach for medial condyle |
| Type 4a | Anterior Hoffa’s | Anterior to posterior lag screw | Standard parapatellar approach (medial or lateral) |
| Type 4b | Bicondylar Hoffa’s | Lag screws depending upon the size of the fracture fragment | Swashbuckler approach or combination of medial and lateral approaches |
| Type 4c | Osteochondral Hoffa’s | Headless screws or bioabsorbable pins | Arthroscopic fixation |
| Type 4d | With associated supracondylar fracture | Lag screws with a rigid locking plate | Swashbucker approach for lateral condyle and subvastus approach for medial condyle |
