Isolated rupture of biceps femoris tendon

Abstract

Authors present a case of rupture of the distal end of the biceps femoris. Injuries at this site are relatively rare. Clinical assessment can be aided by instrumental examinations such as ultrasound and especially NMR. Delayed treatment because of erroneous diagnosis or failure of conservative therapy can result in proximal retraction and atrophy of the muscle belly, requiring more complex surgery. Despite the limited data in the literature, Authors favor immediate surgical treatment of both complete and partial injury of the biceps femoris tendon, particularly in a patient who requires a high level of function.

Common Peroneal Nerve Palsy with Multiple-Ligament Knee Injury and Distal Avulsion of the Biceps Femoris Tendon

“…The biceps femoris is the most powerful flexor of the leg; with its biarticular head, it acts as an external rotator and plays a role in hip extension. When it is compromised, flexion strength is reduced by 30–85% [ 9 , 10 ]. The outcomes with surgical repair of a chronic biceps tendon rupture 4 months after injury have been shown to be poorer than with acute repair [ 11 ].…”

“…The two-staged surgery involved primary repair of the PLC and biceps tendon. Following the repair, the cast fixation and non-weight bearing for 3-4 weeks are required [ 10 ]. ACL reconstruction that is simultaneously performed in an acutely injured knee, prior to the resolution of swelling, pain, and normalization of movement, has been shown to place an individual at a greater risk for postoperative complications in knee movement.…”

Imaging of Tendons of the Knee: Much More than just the Extensor Mechanism

“…Although proximal tendon and muscle belly injuries are common, partial or complete tears of the distal hamstring tendons are relatively rare. 8,[55][56][57][58][59][60][61] Distal injury occurs more typically at the myotendinous junction rather than tear or avulsion of the distal tendon near its osseous attachment (►Figs. 7 and 8).…”

“…7 and 8). 8,57 However, in the setting of knee dislocation, the biceps femoris tendon is one of the most commonly injured extraarticular structures. 62 Radiographs may be normal in the setting of distal hamstring injury, unless an avulsion fracture of the proximal fibula by the biceps femoris tendon is present (►Fig.…”

“…27 The few reports on the surgical treatment of distal tears of the hamstring muscle consist mainly of biceps femoris tears. 12,16,26,27,29,32 Reports of injuries to the distal semimembranosus tendon are even more scarce. 3 …”
