Abstract
Purpose
Most medial collateral injuries require very challenging therapeutic
management even for expert surgeons. After the failure of conservative treatment, the
physician’s first choice should be a minimally invasive surgical technique.
Reconstruction of the medial collateral ligament of the elbow (MCL) with graft is the
most described, demanding, and time-consuming procedure, compared to plication of
the ligament. Our study aims to validate the results concerning the MI70 procedure
(Medial Imbrication through a 70° scope vision), elaborated to imbricate the anterior
bundle of the medial collateral ligament (aMCL) and the anteromedial capsule through
a suture anchor.
Methods
20 patients who suffered from either traumatic proximal MCL lesion or
progressive aMCL elongation with medial pain were included for aMCL plication with a
suture anchor through arthroscopic technique. The aMCL condition was evaluated
using a 70°-scope. Signs of instability were confirmed by the arthroscopic evaluation.
An independent examiner collected the Oxford Elbow Score (OES) and Mayo Elbow
Performance Score (MEPS) before and after the surgery procedure at a minimum 2
years follow-up.
Results
Nineteen patients (95%) report an improvement in the clinical outcomes with a
statistically significant difference between the preoperative and postoperative OES e
MEPS after a minimum of two years of follow-up (p <0.05).
Conclusions
The Mi70 procedure is a novel technique that allows restoration preinjuries
elbow stability and absence of pain. aMCL imbrication with a suture anchor is a
valid alternative in the treatment of medial elbow pain in patients with partial ligament
degeneration or partial traumatic lesions.
