Purpose: The aim of this study is to describe a new surgical procedure to plicate the anterior bundle medial collateral ligament (aMCL) into its humeral footprint using a suture anchor, and to present the results of a preliminary clinical series. Methods: Eight patients with posttraumatic medial elbow pain and signs of medial elbow instability underwent aMCL plication with suture anchors and decompression of ulnar nerve. Arthroscopic evaluation permitted to define signs of minor medial elbow instability; 70°-scope was used to document from an intra-articular point of view of the aMCL status. The patients were then retrospectively evaluated with the Oxford Elbow Score (OES), Mayo Elbow Performance Score (MEPI) and single-assessment numeric evaluation (SANE) by an independent examiner. Results: In all cases, the 70°-scope allowed direct visualization of the aMCL. Lateral subluxation of the coronoid process into the trochlea was observed in all patients. Postoperative median SANE was 50 [35–74.5] points; postoperative median OES was 17 [15.5–31.5] points; postoperative median MEPI was 65 [57.5–72.5] points. None of the patients reported further episodes of medial elbow instability or pain and all patients returned to normal daily activities. Conclusions: The 70°-scope arthroscopic evaluation of the joint allows a direct evaluation of the inner aMCL status. Lateral subluxation of the coronoid process into the trochlea was observed and can be considered a sign of minor medial elbow instability. Mini-open suture anchor aMCL plication is an original technique that enables an anatomic and minimally invasive ligament retension. Clinical relevance: The authors introduce a valid and safe treatment of posttraumatic medial elbow laxity.

Abstract

Purpose: The aim of this study is to describe a new surgical procedure to plicate the anterior bundle medial collateral ligament (aMCL) into its humeral footprint using a suture anchor, and to present the results of a preliminary clinical series. Methods: Eight patients with posttraumatic medial elbow pain and signs of medial elbow instability underwent aMCL plication with suture anchors and decompression of ulnar nerve. Arthroscopic evaluation permitted to define signs of minor medial elbow instability; 70°-scope was used to document from an intra-articular point of view of the aMCL status. The patients were then retrospectively evaluated with the Oxford Elbow Score (OES), Mayo Elbow Performance Score (MEPI) and single-assessment numeric evaluation (SANE) by an independent examiner. Results: In all cases, the 70°-scope allowed direct visualization of the aMCL. Lateral subluxation of the coronoid process into the trochlea was observed in all patients. Postoperative median SANE was 50 [35–74.5] points; postoperative median OES was 17 [15.5–31.5] points; postoperative median MEPI was 65 [57.5–72.5] points. None of the patients reported further episodes of medial elbow instability or pain and all patients returned to normal daily activities. Conclusions: The 70°-scope arthroscopic evaluation of the joint allows a direct evaluation of the inner aMCL status. Lateral subluxation of the coronoid process into the trochlea was observed and can be considered a sign of minor medial elbow instability. Mini-open suture anchor aMCL plication is an original technique that enables an anatomic and minimally invasive ligament retension.
