Arthroscopic release and decortication provide earlier return to work with similar patient satisfaction compared to continued intensive conservative therapy for recalcitrant tennis elbow: a retrospective observational study

INTRODUCTION

Tennis elbow management has primarily been conservative over the years with over 90% of the cases being managed conservatively. Surgical intervention may be necessary only for symptomatic recalcitrant cases of tennis elbow cases. However, there are gaps in the literature when it comes to comparison of the return to pre-operative return to their work and level of activities among patients who undergo arthroscopic management and those who receive conservative management.

METHODS

A retrospective observational study was conducted to compare 23 patients receiving continued intensive conservative (CIC) management in group 1 with 24 patients undergoing arthroscopic release of the extensor carpi radialis brevis and lateral epicondyle decortication (ARD) in group 2. The study had a minimum follow-up period of 3.5 years. The researchers compared the groups in terms of return to work (RTW) at the same intensity or lower level and any changes in their previous work. Objective grip strength and patient-reported outcome measures, such as post-intervention satisfaction level (rated on a scale of 0-100) and visual analog scale (VAS) for residual elbow pain, were also compared between the two groups.

RESULTS

Return to work (RTW) occurred significantly earlier in group 2 (mean 6.13 months) compared to group 1 (mean 4.64 months), and a greater number of patients in group 2 (13/24, 54.2%) were able to return to the same of work. Although not statistically significant, the ARD group exhibited comparable patient satisfaction (p = 0.62) and visual analog scale (VAS) scores for residual elbow pain (p = 0.67). Grip strength was comparable (p = 0.084, 0.121) between the affected and unaffected sides of the bilateral upper extremities and among both groups of patients.

CONCLUSION

The use of ARD for RTE (recalcitrant tennis elbow) indicates a significantly earlier return to work (RTW) at the same or lower intensity level compared to the standard CIC therapy protocol. Objective grip strength was comparable to the non-affected side and among the two groups of patients receiving two different management modalities. Comparable patient-reported satisfaction and residual lateral elbow pain were also noted among both the groups.

Lateral collateral ligament reconstruction in atraumatic posterolateral rotatory instability

Background

Chronic elbow pain has several causes. Instability pain is one of the differential diagnosis. Posterolateral rotatory instability (PLRI) of the elbow results from lateral collateral ligament (LCL) insufficiency. This instability has been recognized in association with trauma of the elbow. The standard treatment of LCL insufficiency is ligament reconstruction with a tendon graft. Treatment outcome of LCL reconstruction in atraumatic PLRI cases has been rarely reported. This study reports the results of LCL reconstruction in patients with chronic lateral elbow pain from atraumatic PLRI.

Materials and methods

Data were collected from 36 patients referred to our institution for surgery because of chronic lateral elbow pain between November 2011 and June 2015. Six patients with atraumatic PLRI underwent LCL reconstruction with tendon graft. Demographic data, number of steroid injections, postoperative clinical examination, Mayo Elbow Performance Index, 11-item version of the Disabilities of the Arm, Shoulder and Hand score, and complications were recorded with a mean follow-up of 24 months.

Results

Reconstruction resulted in significant improvement of pain. The mean postoperative Mayo Elbow Performance Index score was 97.5 (range, 95-100), and the score of the 11-item version of the Disabilities of the Arm, Shoulder, and Hand was 9 (range, 3.3-33). Postoperative instability test results were negative in all patients. Mean postoperative range of motion was 136° in flexion and 1° in extension. No complications were detected at the follow-up assessment.

Conclusions

We consider LCL reconstruction is one of the reference treatments for atraumatic PLRI because it provides effective and reliable results.
