A detaching, V-shaped tibial tubercle osteotomy is a safe procedure with a low complication-rate 4 63 Minor complications In five knees (1.9%) minor complications occurred (table 2). Two patients (0.76%) had a thromboembolic event. The other three complications occurred only once (0.38%): a superficial wound infection with a S. Aureus for which this patient got antibiotics for 6 weeks, a deep flexion contracture of 90 degrees which restored without further surgery after 5 months to 130 degrees and a delayed union. This last patient had to wear an extension brace with restricted flexion without resistance up to 60 degrees until 5 months postoperatively, after which the osteotomy consolidated. No cases of persisting disability in range of motion were seen. Hardware removal Twenty-two knees had the screws removed because of pain or irritation (8.4%).
