Postoperative Rehabilitation of Ulnar Collateral Ligament Reconstruction: A Systematic Review.

The incidence of ulnar collateral ligament injuries has increased over the past few decades with greater participation in overhead throwing sports; however, optimal postoperative management following surgery remains unclear. This systematic review summarizes the latest evidence, on postoperative rehabilitation protocols for patients undergoing ulnar collateral ligament reconstruction (UCLR). Studies published in the English language from the year 2000 to 2019 with a level 1 to 4 grade of evidence and examined rehabilitation protocols following UCLR were eligible for inclusion. A multidatabase search was conducted. Two blinded reviewers screened and graded articles for inclusion and a third independent reviewer resolved any conflicts. Ten of the original 139 studies identified were used for analysis. Surgical techniques as well as rehabilitation protocols varied across studies. Analysis gave strong evidence that a 4-phase postoperative rehabilitation protocol utilizing milestone-based goals is effective in returning athletes back to preinjury levels of activity and sport within 1 year following UCLR.

Repair of the Ulnar Collateral Ligament of the Elbow: Rehabilitation Following Internal Brace Surgery.

SYNOPSIS: Injuries to the elbow in athletes who play overhead sports, especially in baseball pitchers, continue to increase in frequency. The anterior band of the ulnar collateral ligament (UCL), the primary restraint to valgus stress, is commonly injured from throwing. Historically, such injuries have been treated with surgical reconstruction techniques, using a tendon autograft. A recently developed UCL repair procedure with an internal brace, utilizing collagen tape, is gaining popularity. The primary goal of this surgery is to enhance elbow joint stability while the ligament is healing and to allow earlier return to sport after UCL reconstruction. The rehabilitation program following UCL repair with internal brace progresses through a different time frame than after UCL reconstruction. The purpose of this commentary, based on our experience with more than 350 cases, including 79 patients with at least a 1-year postsurgical follow-up, was to describe and provide the rationale for the rehabilitation process following UCL repair with internal brace.

Major League Baseball Pitching Performance After Tommy John Surgery and the Effect of Tear Characteristics, Technique, and Graft Type.

BACKGROUND: Return to play and player satisfaction have been quite high after ulnar collateral ligament reconstruction (UCLR); however, there has been little reported on how outcomes are affected by surgical technique, graft type, and tear characteristics. PURPOSE: To evaluate surgical techniques, graft type, and tear characteristics on Major League Baseball (MLB) performance after UCLR. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: MLB pitchers who underwent primary UCLR at a single institution were included. Tear characteristics included tear location, tear grade, and acuity. Surgical technique and graft type were also collected. Pitching performance statistics, including earned run average (ERA), walks and hits per innings pitched (WHIP), innings pitched, and fastball velocity were evaluated 3 years before and after UCLR. RESULTS: Forty-six MLB pitchers were identified as having primary UCLR. Return to play was 96%, with 82% returning to MLB play. Technique performed showed no difference in performance. As compared with pitchers with gracilis grafts, pitchers with palmaris grafts were younger ( P = .043), played longer after surgery ( P = .012), and returned to play at 100% (35 of 35) versus 82% (9 of 11, P = .010). When compared with pitchers with proximal tears, pitchers with distal tears pitched at higher velocity (93.0 vs 90.6 mph, P = .023) and had better performance before surgery (ERA, P = .003; WHIP, P = .021); however, those with proximal tears improved to match this performance and velocity after reconstruction. As compared with those having partial tears, pitchers with complete tears played longer after surgery (5.9 vs 4.0 years, P = .033), had a better ERA before injury ( P = .041), and had better WHIP ( P = .037) and strikeouts per 9 innings ( P = .025) after reconstruction. Pitchers with chronic tears had a significant improvement in postoperative ERA, from 4.49 to 3.80 ( P = .040). CONCLUSION: Technique performed and graft type used did not affect performance; however, pitchers with palmaris grafts returned at a higher rate than those with gracilis grafts. Distal tears occurred in pitchers with greater velocity and better performance before injury, yet pitchers with proximal tears matched this performance after reconstruction. Pitchers with complete tears played longer after reconstruction. Pitchers who had partial tears had worse performance before injury and after reconstruction, and those with chronic tears saw a significant improvement in ERA with reconstruction.

The success of return to sport after ulnar collateral ligament injury in baseball: a systematic review and meta-analysis.

BACKGROUND: Ulnar collateral ligament injury (UCLI) has significantly increased in overhead sports during the past 2 decades. Differences in return to sport (RTS) and RTS at previous level (RTSP) after UCLI have not been differentiated. METHODS: A computer-assisted literature search of PubMed, CINAHL, Embase, and SportDiscus databases using keywords related to RTS for UCLI was implemented. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for study methodology. Quality assessment was conducted using a modified Downs and Black scale. RESULTS: A total of 22 retrospective, level 3b or 4, studies (n = 2289) qualified for analysis. Overall RTS proportion was 90% (95% confidence interval [CI], 86%-94%) and overall RTSP proportion was 79% (95% CI, 75%-84%), both with significant heterogeneity (P < .001, I2 = 74%-84%). RTS and RTSP proportions were 89% (95% CI, 83%-94%) and 78% (95% CI, 72%-83%) for Major League Baseball players, 91% (95% CI, 77%-99%) and 67% (95% CI, 52%-81%) for Minor League Baseball players, 95% (95% CI, 75%-100%) and 92% (95% CI, 82%-98%) for collegiate players, and 93% (95% CI, 81%-100%) and 83% (95% CI, 77%-89%) for high school players, respectively. Increased earned run average, walks, and hits per inning pitched, decreased innings pitched, and decreased fastball velocity were found after UCLI. CONCLUSION: Low-level, high-bias evidence demonstrates overall RTS proportion is higher than RTSP, regardless of treatment type for UCLI. Although RTS proportions remained consistent across various levels of play, RTSP proportions were lower in professional players, particularly Minor League Baseball compared with collegiate and high school players. Pitching performance significantly decreased postoperatively in most studies.

Avoiding Tommy John Surgery: What Are the Alternatives?

The number of ulnar collateral ligament (UCL) reconstructions being performed has risen sharply in recent years, most notably in the young amateur athlete. While successful outcomes have been reported with reconstruction, the surgery and the associated rehabilitation timeline may be difficult for the nonelite athlete to incur. Return-to-play expectations, along with level of competition, should help guide surgeons in exploring management options. While reconstruction remains a mainstay, focused research exploring nonreconstructive options has expanded. This review discusses the clinical approach to those with UCL injury, including current support for rehabilitation, biologic strategies, and available repair or augmentation alternatives.

[Restoration of ulnar collateral ligament stability of the metacarpophalangeal joint of the thumb]. / Ulnare Kollateralbandplastik des Daumengrundgelenks bei chronischer Instabilität.

OBJECTIVE: Restoration of ulnar collateral ligament stability of the metacarpophalangeal (MP) joint of the thumb with elimination of palmar subluxation while retaining mobility for chronic instability without osteoarthritis. INDICATIONS: Acquired or congenital chronic instability of the MP joint of the thumb with compelling reasons for joint preservation and against arthrodesis, e.g., an arthrodesis or arthritis of adjacent joints. CONTRAINDICATIONS: Arthritis of the thumb MP joint. Contractures of the MP joint. Low natural range of motion of the joint (compared to the contralateral hand). Additional palmar instability with significant hyperextensibility. Infections. Lesions to the median and/or ulnar nerve with impaired active mobility. SURGICAL TECHNIQUE: Anatomical reconstruction of the ulnar collateral ligament and the accessory collateral ligament using a tendon graft (palmaris longus tendon). Ulnar approach, transosseous course of the tendon graft and elimination of subluxation. POSTOPERATIVE MANAGEMENT: Splint for 5 weeks and hand therapy. RESULTS: Of 12 patients undergoing this type of ligament reconstruction, all achieved good stability and pain-free range of motion, which was 60-95% of the contralateral hand. This surgical procedure has few complications and is considered reliable.
