Tapper and Hoover followed 213 patients for 10–30 years after uncomplicated meniscectomy at the Mayo Clinic. Using a structured symptom and disability questionnaire, they asked what the true long-term outcomes of meniscal excision actually are. At the time, the procedure was widely considered either harmless or preferable to leaving a torn meniscus in situ.
In 1969, many surgeons believed complete meniscal excision was either harmless or that failure to remove the torn meniscus would inevitably cause arthritis. Some series reported up to 96% good clinical results — but those were short-term follow-ups defining "good" as returning to work.
Tapper and Hoover showed the reality at 10–30 years: fewer than 40% of patients had normal knees, and 13% were frankly disabled. This paper is why we no longer treat meniscectomy as a cure.
When you have a young female patient with vague mechanical symptoms and no discrete tear on imaging, think twice before recommending meniscectomy. Tapper and Hoover found 40% of women in this series had no true tear. And those patients fared worst of all.
For bucket-handle tears, the data here directly support what we now do: remove only the detached fragment and preserve the peripheral rim. The 67% excellent rate with rim preservation vs 36% with total meniscectomy is the original evidence base for that principle.
This paper catalyzed the basic science work on meniscal load-sharing and hoop stress that followed in the 1970s–80s, and directly influenced the shift toward meniscal repair. Making it one of the most consequential clinical studies in sports medicine history.
