Hypothesis And Background: Although on-field performance metrics are useful in measuring overall success of ulnar collateral ligament (UCL) reconstruction (UCLR) in professional baseball pitchers, they may not comprehensively quantify athletic performance after returning to playing in the league. To utilize fantasy baseball score (FBS) as a novel and objective outcome to assess the quality of return to play in major league baseball (MLB) pitchers who went back to professional pitching after UCLR.

Methods: This is a retrospective observational cohort study of 216 established MLB pitchers who underwent UCLR while in the MLB between the years 1974 and 2018.

Purpose: To assess whether reimbursement for orthopaedic sports procedures adequately compensates for operative time and surgical complexity.

Methods: The National Surgical Quality Improvement Program (NSQIP) database was queried for all orthopedic sports medicine procedures performed greater than 150 times from 2016 to 2018 with regard to operative time, preoperative risk factors, morbidity, and mortality data. Physician work relative value units (wRVU) data were obtained from the 2020 Centers for Medicare & Medicaid Services (CMS) fee schedule.

Increasing numbers of people are playing golf. Golf is a unique sport in that the ability to participate at a high level is not limited by age. In addition, participants tend to play more rather than less as they grow older.

The technique of osteochondral allograft (OCA) transplantation has been used to treat a wide spectrum of cartilage deficiencies in the knee. Its use has been supported by basic science and clinical studies that show it is a safe and effective treatment option. What sets fresh OCA transplantation apart from other cartilage procedures in the knee, is the ability to treat large defects with mature hyaline cartilage.

The isoelastic ultrahigh-molecular-weight polyethylene tension band may be considered an alternative to stainless steel wire for tension band fixation of olecranon fractures. In this article, we present our technique using this isoelastic tension band and describe the outcomes of 7 patients who underwent open reduction and internal fixation of closed, displaced olecranon fractures with minimal or no articular surface comminution. We reviewed medical records and performed physical examinations and functional assessments.

Basal joint arthritis leads to thumb metacarpophalangeal (MCP) hyperextension that may prevent physiologic pinch. Various techniques have been used to address this hyperextension, but most are technically challenging, time-consuming, and not supported by long-term follow-up results. Furthermore, few groups have reported subjective, patient-based outcomes after such procedures.

The elbow is a complex joint consisting of 3 separate but important articulations: the ulnohumeral, radiohumeral, and proximal radioulnar joints. The elbow assists in positioning the hand in space through 2 important motions, flexion-extension and pronation-supination. Although the elbow is not a weightbearing joint, it is subjected to significant loads, especially in overhead and throwing athletes.

Advanced stages of basal joint arthritis are sometimes characterized by an adduction deformity of the first metacarpal and a hyperextension deformity of the unstable metacarpophalangeal (MCP) joint. Stabilizing the MCP joint in these patients is critical to ensure a pain-free repair and efficient pinch mechanism. This study presents the anatomic basis for a novel capsulodesis technique using the volar plate that can be incorporated into any reconstructive basal joint procedure when clinically indicated.

Pitchers are prone to elbow injuries because of high and repetitive valgus stresses on the elbow. The anterior bundle of the medial ulnar collateral ligament (MCL) of the elbow is the primary restraint and is often attenuated with time, leading to functional incompetence and ultimate failure. Pitchers with a history of medial elbow pain, reduced velocity, and loss of command may have an MCL injury in evolution.
