SMay 29The Complete Guide to Patellofemoral Pain Syndrome — Editing, multiple topics — Just editing, but a noteworthy batch of edits to several chapters. I made minor corrections and adjustments to every recently added or revised chapter, and some small but (I hope) meaningful clarifications to how “resting” is presented as a treatment strategy.
LMay 2The Complete Guide to Patellofemoral Pain Syndrome — New sub-topic, patellofemoral joint replacement — Added a substantial discussion of patellofemoral joint replacement, and made a number of other modest improvements to the surgery chapter.
SApr 3The Complete Guide to Patellofemoral Pain Syndrome — Minor upgrades, patellofemoral joint pressure — After publishing part of this chapter as an excerpt, I made several minor improvements, and added one simple diagram.

LDec 20The Complete Guide to Patellofemoral Pain Syndrome — Revised and expanded, trigger points chapter — The section had been short and basic for many years, and many readers would never have guessed how much more I’ve written about this topic. It’s now more thorough and more in tune with the times, including the modern skeptical pespective on trigger points, and a more nuanced discussion of what role they might or might not have in patellofemoral pain.
SDec 19The Complete Guide to Patellofemoral Pain Syndrome — Minor editing, patellofemoral pain vs ITBS — Just a few little improvements, especially harmonizing with the IT band tightness chapter.
LDec 12The Complete Guide to Patellofemoral Pain Syndrome — Many improvements, differential diagnosis — After greatly expanding this chapter in 2022, it was a bit of a mess: thorough but disorganized. I eliminated some egregious rambling (was I drunk?).
