Description
Tomasz Piontek and colleagues outline rimplasty, an arthroscopic operation for isolated kneecap cartilage softening linked to a raised bone rim. Their 2026 technical note concerns patients with patella alta, a high kneecap, and a supratrochlear rim over 3 millimeters, without prior kneecap dislocation. Front knee pain in this group can resist long rehabilitation.
The technique reshapes the rim and rebuilds kneecap cartilage using autologous matrix-induced chondrogenesis, a method that grows cartilage on a scaffold from the patient's own cells, plus limited trochleoplasty, or groove reshaping. It aims to correct the mechanics that overload the kneecap rather than only easing pain. A video case shows a young man whose squatting and stair pain persisted despite rehab. Outcome data for the combined technique still lie ahead.
