Abstract 2 years follow-up after arthroscopic repair for posterolateral rotational elbow instability

Introduction:
Posterolateral rotational instability of the elbow causes pain and instability and is often misdiagnosed as epicondylitis lateralis. The gold standard is ligament reconstruction with a tendon graft, which requires an open approach and may cause additional harvest morbidities due to autograft. This study is a follow-up of 10 patients two years after arthroscopic elbow stabilisation with suture anchors instead of a tendon graft.

Methods:
2-year results after performing elbow arthroscopy with reinsertion of the lateral ulnar collateral ligament and extensor tendons with suture anchors in patients with clinical, mri and intraoperative confirmed PLRI II°-III°. Endpoints were VAS pain (0-10), ROM, the Mayo Elbow Performance Score (MEPS) and the Andrews Carson Score (ACS).

Results:
The mean age was 44 years (95%CI 35-53), 60% male. 4 patients had a history of trauma, all others had been treated for lateral epicondylitis with an average of 2.2 (95%CI 1-4) corticosteroid injections and physiotherapy.

There were statistically significant and clinically relevant improvements in all endpoints
with a reduction in pain by 5.4 pts (95%CI 4.6-6.3) and improvement in MEPS by 37.2 pts (95%CI 28-47)
and ACS by 59 pts (95%CI 50-68). There was no significant reduction in extension (-1°, 95%CI -2.9-3.8)
or flexion (-1.7°, 95%CI -0.6-4.0). There were no complications, one patient did report occasional
tenderness to touch over the knots.

Conclusion:
Arthroscopic stabilization provided a statistically significant and clinically relevant improvement in this
prospective cohort of patients with °II - °III PLRI.
