Graft choice and techniques used in elbow ulnar collateral ligament reconstruction over the last 20 years: a systematic review and meta-analysis

BACKGROUND

Elbow medial ulnar collateral ligament (mUCL) injuries have become increasingly common, leading to a higher number of mUCL reconstructions (UCLR). Various techniques and graft choices have been reported. The purpose of this study was to evaluate the prevalence of each available graft choice, the surgical techniques most utilized, and the reported complications associated with each surgical method.

METHODS

A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysesguidelines. We queried PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases to identify all articles that included UCLR between January 2002 and October 2022. We included all studies that referenced UCLR graft choice, surgical technique, and/or ulnar nerve transposition. Studies were evaluated in a narrative fashion to assess demographics and report current trends in utilization and complications of UCLR as they pertain to graft choice and surgical techniques over the past 20 years. Where possible, we stratified based on graft and technique.

RESULTS

Forty-seven articles were included, reporting on 6671 elbows. The cohort was 98% male, had a weighted mean age of 21 years and follow-up of 53 months. There were 6146 UCLRs (92%) performed with an autograft and 152 (2.3%) that utilized an allograft, while 373 (5.6%) were from mixed cohorts of autograft and allograft. Palmaris longus autograft was the most utilized mUCL graft choice (64%). The most utilized surgical configuration was the figure-of-8 (68%). Specifically, the most common techniques were the modified Jobe technique (37%), followed by American Sports Medicine Institute (ASMI) (22%), and the docking (22%) technique. A concomitant ulnar nerve transposition was performed in 44% of all patients, with 1.9% of these patients experiencing persistent ulnar nerve symptoms after ulnar nerve transposition. Of the total cohort, 14% experienced postoperative ulnar neuritis with no prior preoperative ulnar nerve symptoms. Further, meta-analysis revealed a significantly greater revision rate with the use of allografts compared to autograft and mixed cohorts (2.6% vs. 1.8% and 1.9%, P = .003).

CONCLUSIONS

Most surgeons performed UCLR with palmaris autograft utilizing a figure-of-8 graft configuration, specifically with the modified Jobe technique. The overall rate of allograft use was 2.3%, much lower than expected. The revision rate for UCLR with allograft appears to be greater compared to UCLR with autograft, although this may be secondary to limited allograft literature.

Lateral collateral ulnar ligament reconstruction techniques in posterolateral rotatory instability of the elbow: A systematic review

BACKGROUND

Elbow chronic instability is a disable complication, presenting as recurrent joint subluxations or dislocations. This systematic review aims to assess (1) the clinical outcome and (2) the complication rates of the surgical techniques currently used in the management of posterolateral rotatory elbow instability.

METHODS

OVID-MEDLINE®, SCOPUS, and PubMed were searched from January 2009 to February 2019 to identify relevant studies. The search terms used were "LUCL", "Posterolateral dislocation", "Elbow Docking technique", "Elbow Jobe technique" and "Elbow single strand technique". The methodological qualities of the studies were evaluated, relevant data were extracted.

RESULTS

Three studies, published between 2012 and 2015, were included in this review. No studies concerning the single strand technique met the inclusion criteria. The included studies had a level of evidence IV and recruited 33 patients undergoing a Jobe technique reconstruction and 8 patients undergoing a Docking technique. Jobe procedure registered better clinical and functional outcome, assessed using the Mayo Clinic Elbow Performance Scale (MEPS), compared with patients managed with Docking technique. Nonetheless, this difference is not significant. There was not a significantly different complication rate (p = 0.57) between patients treated with these two different techniques.

CONCLUSION

This systematic review showed that both Jobe and Docking techniques are safe and effective in the treatment of posterolateral elbow instability. However, future studies with larger sample size and a longer follow-up interval are needed to draw stronger conclusions on the efficacy of the different LUCL surgical reconstruction techniques.

A systematic review of ulnar collateral ligament reconstruction techniques

BACKGROUND

Ulnar collateral ligament (UCL) reconstruction of the elbow has become increasingly more frequent among elite overhead athletes. The purpose of this study was to conduct a systematic review comparing the clinical outcomes and biomechanical results of the Jobe, modified Jobe, docking, modified docking, Endobutton, and interference screw techniques for UCL reconstruction.

HYPOTHESIS

The docking technique will have significantly fewer complications and improved return-to-play rate.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

Using the Medline PubMed, Cochrane, and EMBASE databases, a search was performed of all published articles, including randomized controlled trials, cohort studies, and case series, examining UCL reconstructions performed using one of the above noted techniques and excluding case reports and hybrid techniques. Statistical analysis was performed using a χ(2) test of independence and 2-proportion Z test.

RESULTS

A total of 21 studies, 7 biomechanical and 14 clinical, met the inclusion criteria. There were 1368 patients. The overall complication rate was 18.6% (255/1368), further subdivided into 21 for the Jobe technique (29.2%), 203 for the modified Jobe technique (19.1%), 2 for the interference screw technique (10.0%), 2 (4.3%) for the modified docking technique, and 10 for the docking technique (6.0%). The most common complication across all studies was ulnar nerve neurapraxia in 176 patients (12.9%). The overall rate of return to play was 78.9%.

CONCLUSION

Ulnar collateral ligament reconstruction utilizing the docking technique results in a significantly higher rate of return to play and a lower complication rate when compared with the Jobe and modified Jobe techniques.

CLINICAL RELEVANCE

A lower complication rate can lead to increased rates of return to play and better outcomes postoperatively.
