Epidemiology of Injuries Identified at the NFL Scouting Combine and Their Impact on Performance in the National Football League: Evaluation of 2203 Athletes From 2009 to 2015.

BACKGROUND: At the annual National Football League (NFL) Scouting Combine, the medical staff of each NFL franchise performs a comprehensive medical evaluation of all athletes potentially entering the NFL. Currently, little is known regarding the overall epidemiology of injuries identified at the combine and their impact on NFL performance. PURPOSE: To determine the epidemiology of injuries identified at the combine and their impact on initial NFL performance. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: All previous musculoskeletal injuries identified at the NFL Combine from 2009 to 2015 were retrospectively reviewed. Medical records and imaging reports were examined. Game statistics for the first 2 seasons of NFL play were obtained for all players from 2009 to 2013. Analysis of injury prevalence and overall impact on the draft status and position-specific performance metrics of each injury was performed and compared with a position-matched control group with no history of injury or surgery. RESULTS: A total of 2203 athletes over 7 years were evaluated, including 1490 (67.6%) drafted athletes and 1040 (47.2%) who ultimately played at least 2 years in the NFL. The most common sites of injury were the ankle (1160, 52.7%), shoulder (1143, 51.9%), knee (1128, 51.2%), spine (785, 35.6%), and hand (739, 33.5%). Odds ratios (ORs) demonstrated that quarterbacks were most at risk of shoulder injury (OR, 2.78; P = .001), while running backs most commonly sustained ankle (OR, 1.39; P = .040) and shoulder injuries (OR, 1.55; P = .020) when compared with all other players. Ultimately, defensive players demonstrated a greater negative impact due to injury than offensive players, with multiple performance metrics significantly affected for each defensive position analyzed, whereas skilled offensive players (eg, quarterbacks, running backs) demonstrated only 1 metric significantly affected at each position. CONCLUSION: The most common sites of injury identified at the combine were (1) ankle, (2) shoulder, (3) knee, (4) spine, and (5) hand. Overall, performance in the NFL tended to worsen with injury history, with a direct correlation found between injury at a certain anatomic location and position of play. Defensive players tended to perform worse compared with offensive players if injury history was present.

Mini-Open Posterior Compartment Release for Chronic Exertional Compartment Syndrome of the Leg.

Chronic exertional compartment syndrome (CECS) is a well-recognized cause of leg pain in endurance athletes. Surgical fasciotomy for posterior leg CECS historically has inferior clinical results compared with anterior and lateral compartment release. Poor surgical technique with inadequate release may contribute to less reliable outcomes. In this Technical Note with accompanying video, we describe a mini-open approach for posterior CECS of the leg.

Latarjet Technique for Treatment of Anterior Shoulder Instability With Glenoid Bone Loss.

Anterior glenohumeral instability is a common clinical entity, particularly among young athletic patient populations. Nonoperative management and arthroscopic treatment of glenohumeral instability have been associated with high rates of recurrence, particularly in the setting of glenohumeral osseous defects. Coracoid transfer, particularly the Latarjet procedure, has become the treatment of choice for recurrent anterior glenohumeral instability in the setting of osseous deficiencies greater than 20% to 30% of the glenoid surface area and may also be considered for the primary treatment of recurrent instability in the high-risk contact athlete, even in the setting of limited osseous deficiency. The following Technical Note provides a diagnostic approach for suspected glenohumeral instability, as well as a detailed description of the congruent-arc Latarjet procedure, performed with a deltoid split, with its postoperative management.

Arthroscopic Superior Capsule Reconstruction Technique in the Setting of a Massive, Irreparable Rotator Cuff Tear.

Massive, irreparable rotator cuff tears are challenging to treat and associated with pain and severe limitation in shoulder elevation due to the proximal migration of the humeral head and, consequently, subacromial impingement. Furthermore, retraction of the tendons in combination with fat infiltration and muscular weakness results in unpredictable treatment outcomes. While conservative treatment may be warranted for low-demand patients, surgical treatment is often indicated for a successful return to activities of daily living as well as an improved quality of life. The reported failure rate of rotator cuff repair for the treatment of a massive rotator cuff tear varies. However, this failure is often found at the interface between the tendon and tendon footprint. Several techniques have been reported to address this pathology, including muscular transfer, arthroscopic debridement, augmentation procedures, and superior capsule reconstruction. In particular, superior capsule reconstruction has been reported as a safe and effective method to treat a massive, irreparable rotator cuff tear. The purpose of this Technical Note is to describe our preferred technique of a superior capsule reconstruction for the treatment of a massive, irreparable rotator cuff tear.

Ankle impingement.

Ankle impingement is a syndrome that encompasses a wide range of anterior and posterior joint pathology involving both osseous and soft tissue abnormalities. In this review, the etiology, pathoanatomy, diagnostic workup, and treatment options for both anterior and posterior ankle impingement syndromes are discussed.

Posterior Tibial Arterial System Deficiency Mimicking Chronic Exertional Compartment Syndrome: A Case Report.

CASE: A 15-year-old female competitive high school basketball player presented as an outpatient with a 3-month history of bilateral exertional calf pain. Patient history and compartment pressure measurements were consistent with the diagnosis of chronic exertional compartment syndrome, and the patient underwent bilateral fasciotomies. Postoperatively, her symptoms recurred and she was found to have a deficient posterior tibial arterial system bilaterally, as confirmed on advanced imaging. CONCLUSION: We advocate the careful consideration of vascular etiologies in athletes who present with exertional leg pain.

Five-strand hamstring autograft for anterior cruciate ligament reconstruction.

Four-strand hamstring autograft is a common choice for anterior cruciate ligament reconstruction. A potential disadvantage of hamstring autograft for anterior cruciate ligament reconstruction is the inherent variability in graft diameter. Multiple studies have shown increased revision rates when using an undersized hamstring graft. Using an EndoButton (Smith & Nephew, Andover, MA) for femoral tunnel fixation, we convert a standard quadrupled hamstring graft into a 5-strand graft by creating 3 equal strands of the typically larger semitendinosus combined with a double-stranded gracilis. This technique may help alleviate some surgeon reluctance to use a hamstring graft by providing an intraoperative "bailout" option for an unexpectedly small tendon. On the basis of current data, increasing the diameter of the graft in these situations may decrease revision rates.

Arthroscopic transosseous-equivalent rotator cuff repair.

Rotator cuff repair techniques continue to evolve in an effort to improve repair biomechanics, maximize the biologic environment for tendon healing, and ultimately improve patient outcomes. The arthroscopic transosseous-equivalent technique was developed to replicate the favorable tendon-bone contact area for healing seen in open transosseous tunnel repair. In this technical note and accompanying video, we present our all-arthroscopic transosseous-equivalent rotator cuff repair technique with a focus on technical pearls.

Anatomic anterior cruciate ligament reconstruction with a flexible reamer system and 70° arthroscope.

Anterior cruciate ligament (ACL) reconstruction techniques continue to evolve as surgeons seek to improve surgical process and outcome measures. On the basis of published data showing improved biomechanics, many surgeons now attempt to better re-create native ACL anatomy in reconstruction. Use of flexible reamer technology and a 70° arthroscope allows for excellent visualization of the native ACL anatomy, as well as precise and independent drilling of the tibial and femoral reconstruction tunnels, while offering several surgical and technical advantages compared with other drilling techniques. This technical note with accompanying video describes our use of the Smith & Nephew Clancy anatomic cruciate guide/flexible drill system (Smith & Nephew, London, England) with a 70° arthroscope.

Clinical success of biceps tenodesis with and without release of the transverse humeral ligament.

BACKGROUND: Multiple methods for biceps tenodesis exist, but long-term studies have demonstrated high failure rates. We hypothesized that tenodesis techniques that do not release the biceps sheath are associated with a higher surgical revision rate than those that do. METHODS: A retrospective study was conducted of 127 biceps surgeries over a 2-year period. The mean follow-up post surgery was 22 months (range, 6-59). Clinical failure was defined as ongoing pain localized in the biceps groove, severe enough to warrant revision surgery. RESULTS: When all techniques that released the biceps sheath (6.8%, 4/59) were compared to those that did not release the biceps sheath (20.6%, 14/68), a statistically significant difference was found, P = .026 (chi-square). Proximal arthroscopic techniques were revised at a significantly higher rate than distal tenodesis techniques (P = .005). CONCLUSION: Biceps tenodesis techniques which do not release the biceps sheath or remove the tendon from the sheath have increased revision rates, compared to techniques that do. This may be supportive evidence for the theory that residual pain generating elements in the biceps groove is a cause of failure of proximal tenodesis methods.

Acromionectomy and deltoid deficiency: a solution.

UNLABELLED: Deltoid insufficiency after iatrogenic or traumatic acromionectomy results from separation of the deltoid from its origin and mechanical fulcrum. Subsequent retraction of the tendon and formation of subdeltoid adhesions to the cuff and humerus result in stiffness and pain. We evaluated clinical outcomes of patients treated with autogenous tricortical iliac crest bone graft combined with deltoid reconstruction or deltoidplasty for deltoid insufficiency after acromionectomy. We retrospectively reviewed four patients, three males, and one female treated with deltoidplasty reconstructions as revision surgery. Their mean age was 41 years, and the minimum followup was 41 months (mean, 50 months; range, 41-66 months). There were three work-related injuries. Outcomes evaluated were pain relief (visual analog score), American Shoulder and Elbow Surgeons score, cosmesis, and complications. The mean pain score improved from 8 (range, 3-10) preoperatively to 1 (range, 0-3) postoperatively. The mean American Shoulder and Elbow Surgeons score improved from 31 +/- 14 to 68 +/- 13. One patient required revision deltoidplasty for abductor weakness. Three patients underwent hardware removal. One patient who underwent concurrent latissimus dorsi transfer had limited functional improvement but decreased pain. Two patients had improved cosmesis. All had CT scans with three-dimensional reconstructions documenting union. All patients stated they would undergo the procedure again. LEVEL OF EVIDENCE: Level IV, therapeutic study.
