The peritenon is identified superiorly, and the peritendonous flaps are elevated to reveal the chronic, scarred patellar tendon rupture (approximately 3.5 cm in the midsubstance of the tendon) (Figure 1(a)).

Where coverage of tendon by some soft tissue is not possible preservation of the peritenon is essential for tendon survival.50 If the peritenon is soft, then a moist dressing is applied over it.
The Achilles tendon, like the triceps tendon, does not have a tendon sheath and is surrounded by fibrofatty tissue called the peritenon. Tendinosis can occur at the insertional site and presents as increased signal, thickening of the tendon, and focal pain at the insertion site.
The dissection plane is between the peritenon and the neurovascular bundle, with the neurovascular bundle being taken with the flap.
