Long axis ultrasound image shows a full thickness footprint supraspinatus tear superimposed on degenerative tendinosis.. Tear outline is well appreciated from distension of the peritendinous and subdeltoid bursal space during percutaneous treatment with tenotomy and liquid platelet rich plasma.

Ultrasound documented a 9mm x 14mm partial width full thickness footprint tear of the anterior to mid right supraspinatus with tendinosis of most of the tendon and enthesopathy at the greater tuberosity of the humeral head ( Figure 1).
At follow up there is neotendon infilling in place of the tear defect.. The lateral tear margin has retracted with mild interval attrition of the supraspinatus tendon. At the time of this follow up study the patient had a dramatic return to a completely pain free state and had full range of movement with no dysfunction.

The lateral margin of the tear merged with this neotendon tissue with mild medial retraction ( Figure 2).
