Knotless Suture Anchor Fixation of a Traumatic Osteochondral Lesion of the Lateral Femoral Condyle

Abstract

Osteochondral injuries commonly occur after lateral patellar instability events. Recognition and early intervention of displaced fragments is key to maintaining the viability of the fragment and congruency of the articular surface. Multiple fixation techniques exist for achieving stable fixation of displaced osteochondral lesions, including metal or bioabsorbable screws and all suture techniques. In this Technical Note, we describe a technique for internal fixation of a displaced osteochondral fragment of the lateral femoral condyle using knotless suture anchors. This technique affords minimally invasive restoration of the native anatomy with excellent stability of the fracture fragment, allowing early range of motion and ambulation.

Suture-Bridge Fixation of Osteochondral Fractures and Osteochondritis Dissecans in the Knee: Excellent Rates of Early Lesion Stability and Osseous Union

“…8,14,24,31 Several osteochondral and chondral fracture fixation methods have been developed and described, including bone plugs, bioabsorbable pins, meniscal arrows, fibrin glue, metallic and bioabsorbable headless compression screws, and, more recently, suture-bridge constructs. 13,20,29,31,46 The optimal osteochondral and chondral fracture fixation method to minimize implant-related complications or reoperation remains unclear and continues to present challenges to the treating surgeon.…”

Arthroscopic In Situ Fixation of Osteochondral Fragments on the Weightbearing Area of the Knee Joint With a Single Anchor

“…In traditional surgery for fixing free osteochondral fragments with suture anchors, the number of suture anchors is usually more than one. 6 In addition to increasing the economic burden of patients, the application of anchor may further destroy the local mechanical structure, especially for patients with osteoporosis. The above factors will affect the patient's recovery.…”

Knotless Tendoscopic Peroneal Retinaculum Repair Technique for Recurrent Peroneal Tendon Dislocation

“…To avoid these problems, knotless anchors are used in many areas. [12][13][14] This procedure is a knotless technique. Thus, it can eliminate the challenges of knots.…”
