INTRODUCTION Surgical repair of tendon, including rotator cuff injury, are common procedures, however structural failure of the surgical repair is a common complication of the surgery, and in some instances there is a need to replace injured tendon. There is therefore a recognized need to generate tissue engineered tendons for repair and replacement of damaged or diseased tendon (Derwin et al, ...

Distal biceps tendon ruptures are a result of an eccentric load onto a flexed elbow and can lead to loss of flexion and supination strength. Surgical treatment is a well-accepted treatment that can improve flexion and supination strength, however, can be associated with a number of surgical complications. The case presented here describes a vascular injury sustained during a distal biceps tendo...

Current repair techniques do not re-establish normal bone-tendon (B-T) or tendon-muscle (T-M) junctions. Optimizing the strength and function at these ...

Loss of experimental animals due to tendon repair failure results in the need for additional animals to complete the study. We designed a relief proximal to the flexor digitorum profundus (FDP) tendon repair site to serve as a "safety incision" to prevent repair site ruptures and maximize safety incision-to-suture strength. The FDP tendons were dissected in 24 canine forepaws. The 2nd and 5th t...

A histologically normal insertion site does not regenerate following rotator cuff tendon-to-bone repair, which is likely due to abnormal or insufficient gene expression and/or cell differentiation at the repair site. Techniques to manipulate the biologic events following tendon repair may improve healing. We used a sheep infraspinatus repair model to evaluate the effect of osteoinductive growth...

A paucity of literature exists on quadriceps tendon reruptures. Failed quadriceps tendon repair can cause significant morbidity and disability. Surgical management of quadriceps tendon rerupture can be challenging due to tissue degeneration, tendon retraction, muscle atrophy, and poor bone fixation. A lack of guidance in the literature exists on the appropriate surgical techniques for managing ...

BACKGROUND To date, repair of the lacertus in distal biceps tendon ruptures, recommended by some, has not been evaluated. The goal of these biomechanical experiments was to evaluate the degree to which its repair increases the strength of a distal biceps tendon repair. HYPOTHESIS An intact or repaired lacertus fibrosus will increase the strength of a distal biceps tendon repair. STUDY DESIG...

Repair of a torn quadriceps tendon is necessary to restore the extensor mechanism of the knee. Traditional repair involves transosseous sutures tied over bone bridges on the inferior pole of the patella. Suture anchor repair has been shown to be stronger than transosseous repair and facilitates a smaller incision. Suture tape can improve the strength of the suture-tendon interface, and when com...

Background: Triceps tendon tear has a low incidence. Therefore, surgical repair of the triceps is performed only by small number orthopedic surgeons. Indications: To provide information regarding current treatment algorithm and technique. Technique Description: The exposed through posterior approach. then longitudinally split to expose deep degenerated tissue. tissue any existing osteophytes ar...
