Delayed repair of the distal biceps brachii tendon can lead to the formation of scar tissue and coiling of the tendon. Dissection of the scar tissue and unraveling of the tendon may allow for anatomic repair to the radial tuberosity. A 50-year-old man had a distal biceps brachii tendon tear with an intact lacertus fibrosis. Surgery was performed 22 days after injury. On inspection, the distal b...

Peroneal tendon pathology can range from simple longitudinal tears of one unit, to signifi cant compromise of one of both units, to complete rupture. Repair techniques may differ based on the degree of tendon damage and the personal philosophy of the surgeon relative to their views regarding tendon augmentation. The purpose of this article is to describe techniques that have been employed for p...

The primary goal of this study was to evaluate a cross-linked acellular porcine dermal patch (APD), as well as platelet-rich plasma fibrin matrix (PRPFM), for repair of acute Achilles tendon rupture in a sheep model. The 2 surgically transected tendon ends were reapproximated in groups 1 and 2, whereas a gap was left between the tendon ends in group 3. APD was used to reinforce the repair in gr...

Stem cell research plays an important role in orthopedic regenerative medicine today. Current literature provides us with promising results from animal research in the fields of bone, tendon, and cartilage repair. While early clinical results are already published for bone and cartilage repair, the data about tendon repair is limited to animal studies. The success of these techniques remains in...

Tissue engineering techniques using novel scaffold materials offer potential alternatives for managing tendon disorders. Tissue engineering strategies to improve tendon repair healing include the use of scaffolds, growth factors, cell seeding, or a combination of these approaches. Scaffolds have been the most common strategy investigated to date. Available scaffolds for tendon repair include bo...

BACKGROUND Adhesion formation limits functional recovery after flexor tendon repair. Various growth factors have been implicated in the adhesion scar process. Early growth response factor-1 (EGR-1), a transcription factor associated with synthesis of a variety of key fibrotic growth factors and expression of extracellular matrix genes, has never been identified in a tendon repair model. METHO...

The repair of flexor tendons (zones I and II) is a technique-intensive surgical undertaking. It requires a strong understanding of the anatomy of the tendon sheath and the normal relationship between the pulleys and the flexor digitorum superficialis and flexor digitorum profundus tendons in the digit. Meticulous exposure, careful tendon retrieval, and atraumatic repair are extremely important,...

The formation of fibrocartilage at the healing site following a rotator cuff tear repair is a major problem in the field of tendon‑bone healing. The present study aimed to enhance the healing of the tendon‑bone interface following rotator‑cuff tear repair by the interposition of hydroxyapatite (HA) encapsulated with transforming growth factor β1 (TGFβ1). Using an acute rotator cuff repair model...

Baskies M, Tuckman DV, Paksima N. Management of flexor tendon injuries following surgical repair. Bull NYU Hosp Jt Dis. 2008;66(1):35-40. Remarkable strides have been made in the treatment of flexor tendon injuries in the past 40 years. Advances in the understanding of flexor tendon anatomy, nutrition, healing, and biomechanics has significantly improved the treatment of these challenging injur...

Although uncommon, rotator cuff tears that occur medially at the musculotendinous junction can result from acute trauma, anatomic force imbalance, or medial row cuff failure following a previous rotator cuff repair. The quality of the torn muscle and tendon along with the length of the remnant tendon stump should be considered before deciding on the most appropriate repair technique. When muscl...
