Description
Only and colleagues analyze healing after a kneecap-realigning bone operation in this 2026 study of tibial tubercle osteotomy, a procedure that cuts and shifts the shinbone bump where the patellar tendon attaches. They examined what happens at the cut bone's lower edge, where it meets the front of the shin shaft, using measurements on serial X-rays.
The cohort covered 101 knees operated between 2009 and 2015, mostly in young women with a mean age of 21 years. By four months, 62 percent of knees showed radiographic healing at the interface in the films available. Eleven percent developed gap resorption, the cut edge dissolving back by more than two millimeters, and four tibial fractures occurred between 18 and 201 days after surgery. No measured factor, including starting gap size or how far the bone was shifted, statistically predicted fracture, leaving gap resorption as the one warning sign.
