Treatment of Symptomatic Acromioclavicular Joint Instability by a Docking Technique: Clinical Indications, Surgical Technique, and Outcomes

Reconstruction of the Acromioclavicular Ligament Complex Using Dermal Allograft: A Biomechanical Analysis

“…4 The second procedure, the modified ACCR (MADOK procedure), involves a docking technique for reconstructing the superior AC ligament along with repairing the native AC ligaments. 9 In their small case series of 15 patients, the authors found that the MADOK procedure provided significant improvement in outcome scores at a mean follow-up of 3 years. 9 Although these techniques offer repair or reconstruction without the need of additional graft, they do have several limitations.…”

“…Overall, the current study mirrors the findings of others in that excessive rotational torque was the most difficult to control. 9,15 There are 2 similarly described repair techniques that involve reconstituting the AC joint. 4,9 First, the anatomic CC ligament reconstruction, which wraps the entire AC joint with the remaining semitendinosus tendon after CC ligaments reconstruction, has shown promising results for posterior translational and rotational stabilities in a cadaveric biomechanical study.…”

“…Therefore, recent biomechanical and clinical studies have advocated for reconstruction or repair of both the CC and AC capsule for stabilization. [4][5][6][7][8][9][10] The acromioclavicular ligament complex (ACLC) has been reported as the primary posterior stabilizer of the AC joint. [11][12][13][14] A previous biomechanical study demonstrated that dissection of the entire ACLC (with intact CC ligaments) reduced the resistance force of the AC joint against posterior translation to less than 25% when compared with the native ligament complex.…”

Accurate Bone Tunnel Location Based on Three-Dimensional Printing Navigation Module Technology in Coracoclavicular Ligament Reconstruction: Virtual Model vs. Real Model

“…Fixation of the AC joint and reconstruction of the coracoclavicular (CC) ligament have become extremely fundamental surgical methods [2,3,4]. Anatomic CC ligament reconstruction could help restore arm function by rectification of the deformity for the acquisition of static and dynamic stability [19]. In CC reconstruction method, the Modified Weaver-Dunn technique was the most widely adopted [20].…”
