Biceps femoris snapping and friction on the fibular head secondary to abnormal distal tendon insertion: 15 cases and a literature review.

Introduction: Abnormal biceps femoris distal tendon insertion can cause tendon snapping, as is well-known in the literature. The presenting symptom is lateral knee pain, often during sports activities and cycling in particular. The present study tested two hypotheses: abnormal biceps femoris insertion on the fibular head may cause painful friction without clinical snapping, whether visible, audible or palpable; surgical correction achieves good results for pain and return to sport, regarding both snapping and friction.

Neurovascular anatomic relationships to arthroscopic posterior and transseptal portals in different knee positions.

Background: No study exists that directly measures the distances between posterior portals and the popliteal artery under arthroscopic conditions.

Purpose: To define the anatomic relationship between the neural structures and standard posterior arthroscopic portals and between the popliteal artery and posterior as well as transseptal portals in different knee positions.

Study Design: Descriptive laboratory study.

An anterior ankle arthroscopic technique for retrograde osteochondral autograft transplantation of posteromedial and central talar dome cartilage defects.

Purpose: The purpose of this study was to present an arthroscopic technique for the treatment for posteromedial and central cartilage defects of the talus using anterior arthroscopic portals and without performing a medial malleolar osteotomy.

Methods: Nine fresh cadavers were dissected. Autografts were implanted under arthroscopy using a retrograde osteochondral transplantation system, and their position was estimated using specific angular calibrators and later confirmed by software analysis of two photographs of the disarticulated ankle joint.

Arthroscopic retrograde osteochondral autograft transplantation for cartilage lesions of the tibial plateau: a prospective study.

Background: There are only 2 reported cases of arthroscopic retrograde osteochondral autograft transplantations regarding tibial plateau cartilage defects.

Purpose: To present a detailed description of arthroscopic retrograde osteochondral autograft transplantation of the tibial plateau as well as to provide its advantages and disadvantages in comparison with other techniques.

Study Design: Case series; Level of evidence, 4.

Arthroscopic treatment of a talar neck fracture: a case report.

Unlabelled: Talar neck fractures are severe injuries, and their complications can lead to significant functional disability. Open reduction and internal fixation still constitute the treatment of choice. We report a case of a patient with a Hawkins type III talar neck fracture who was treated successfully with the use of an entirely arthroscopic technique.

Fixation of posterior cruciate ligament avulsion fracture with the use of a suspensory fixation.

Purpose: Posterior cruciate ligament (PCL) avulsion fractures are uncommon injuries, and their treatment, still, remains difficult. There are procedures described in the literature which are minimal invasive and use either sutures or screws to stabilize the avulsed fragment. The purpose of this study was to present an innovative arthroscopic technique using a suspensory device with specific biomechanical properties.
