Fairbank's 1948 landmark study compared pre- and post-operative radiographs in 107 knees at intervals from 3 months to 14 years after meniscectomy. It asked a then-controversial question: does removing the meniscus cause measurable structural joint changes, and if so, why? The answer established both a durable classification system and the foundational argument that the meniscus bears load.
At the time of this paper, menisci were widely regarded as vestigial embryological remnants with little functional consequence — removing them was considered a routine, low-risk procedure. Fairbank challenged that assumption directly, providing the first systematic radiographic evidence that meniscectomy produces structural joint changes and the first biomechanical argument that the meniscus actively bears load.
The practical implication is now embedded in surgical training: when you perform arthroscopic meniscal surgery, preserve as much functional tissue as possible. Resect only the unstable fragment. Every millimeter of retained meniscus reduces the relative overload Fairbank described.
When a patient returns years after meniscectomy with medial compartment pain, look for Fairbank changes on plain films. Ridge formation on the femoral condyle, joint space narrowing, or condyle flattening. These are not incidental findings; they are the structural signature of lost load-sharing that Fairbank first characterized in 1948.
Subsequent long-term studies (Roos et al. 1998 at 21 years, Englund et al. 2003 at 16 years) confirmed what Fairbank could only speculate: those radiographic changes do progress to osteoarthritis, validating his caution that meniscectomy is not a benign procedure.
