AI Article Synopsis
- The study aimed to assess the safety, reproducibility, and enforceability of four potential arthroscopic entry points in the foot.
- The evaluation involved 19 cadaveric feet where distances from the arthroscopic portals to important neurovascular structures were precisely measured.
- Results indicated that the medial and dorsomedial portals are safely distanced from the saphenous vein and nerve, while other portals also maintained acceptable margins from nearby nerves and arteries.
Article Abstract
Background: The objectives of the study were to evaluate the safety of hypothetical arthroscopic portals from talonavicular joint and to evaluate their reproducibility and enforceability.
Methods: 19 cadaveric feet were marked and four arthroscopic portals were made (medial, dorsomedial, dorsolateral and lateral). The specimens were dissected in layers and the distances between neurovascular structures and the trocars were measured.
Results: Medial and dorsomedial portals were in average 8.3 and 8.7, respectively, to the saphenous vein and nerve. Dorsolateral portal was in average 8.1mm to the deep peroneal nerve and dorsalis pedis artery, and 9.1mm to the medial dorsal cutaneous branch of the superficial peroneal nerve. Lateral portal was in average 12.3mm to the intermediate dorsal cutaneous branch of the superficial peroneal nerve.
Conclusion: Tested portals shown to have a good safety margin for the foot neurovascular deep dorsal structures and an acceptable safety margin for the superficial neurovascular structures.

Long head of the biceps tendon pathology is a well-described proximal shoulder pain generator. While optimal treatment strategy remains controversial, popular operative management includes biceps tenodesis. However, appropriate restoration of the anatomic length-tension relationship of the biceps with tenodesis remains a challenge.

Background: Superior labrum anterior-posterior (SLAP) lesions are common shoulder injuries. The 10-type classification system has been widely used to diagnose SLAP lesions since it was proposed. However, growing evidence from arthroscopic studies indicates the existence of many SLAP lesions, especially those associated with superior glenoid humeral ligament (SGHL) injuries, that were not included in the initial classification.

Avulsion of the triceps tendon is a rare injury accounting for less than 1% of all tendon injuries. The triceps is an extensor of the elbow and causes compromised function if left untreated. Complete ruptures should be treated with early repairs for satisfactory outcomes.

The popliteal cyst is a common condition that causes disturbing symptoms. Several arthroscopic techniques are combined to treat the enlargement of communication and decompose the cyst wall, aiming to reduce recurrence. We propose a technique that involves resecting the posteromedial valve mechanism and excising the cyst wall through a 2-posteromedial portal approach.
