The Hoffa fracture is an uncommon fracture. There is a lot of confusion about its diagnosis and management with several conflicting reports in literature. We reported a 25-year-old patient with non-union of Hoffa fracture, and meanwhile tried to develop an algorithm-based treatment for Hoffa fractures. A systematic review of the available literature was performed. Medline, Embase, the Cochrane Library and PubMed were searched for relevant articles. Fifty-five articles were reviewed, and the clinical knowledge base was summarized. The understanding of the mechanism of trauma has become more nuanced. The literature has also evolved to classify the fracture with the purpose of surgical management in mind. This can be used to plan approach and fixation with preservation of blood supply. Classification can also prognosticate the outcomes in Hoffa fracture.

Background: Automobile exhaust is an important cause of air pollution, which is a leading health menace and is growing perpetually. Traffic police personnel are exposed to automobile exhaust more than anyone else, and the resulting lung involvement may be asymptomatic. Materials and Methods: This observational cross-sectional study was conducted among 136 traffic police personnel, aged 18–59 years, working for more than 6 months in the traffic police of Kashmir valley. In addition, 140 age- and sex-matched, healthy unexposed Kashmiri's served as controls. Pulmonary functions were measured by RMS Helios 401 PC based spirometer. Results: Sixteen (11.2%) out of 136 traffic police personnel had abnormal pulmonary function test (PFT) as compared to 5 (3.6%) out of 140 controls. Traffic police personnel's had significantly declined forced expiratory volume in 1 s (FEV 1) and forced vital capacity. Eight (5.8%) had obstructive, 7 (5.1%) had restrictive, and 1 (0.7%) traffic police personnel had mixed pattern on PFT. Duration of exposure to automobile exhaust of more than 10 years was significantly associated with pulmonary function abnormality (P = 0.038). Conclusion: Air pollution due to automobile exhaust may be the factor responsible for pulmonary function abnormalities in traffic police personnel. Besides protective measures during duty hours, traffic police personnel should be subjected to periodic assessment of their lung functions.
