• CONTEXT
    • The infrapatellar fat pad (IFP) is in the anterior knee compartment and may be a major pain generator.
  • EVIDENCE ACQUISITION
    • A PubMed database search using the terms Hoffas fat pad, anterior interval, and infrapatellar fat pad was performed from the years 1970 to 2015.
  • STUDY DESIGN
    • Clinical review.
  • LEVEL OF EVIDENCE
    • Level 5.
  • RESULTS
    • Limited research exists examining the role of the IFP in relation to potential treatment and rehabilitation implications.
  • CONCLUSIONS
    • Alterations in IFP mobility, whether the result of postsurgical scarring or faulty movement patterns, result in pain and disability in a variety of patient populations. The majority of treatment approaches are driven by the surgical technique.
