Intrarater and Interrater Reliability of Radiographic Characteristics in Skeletally Immature Patients With Anterior Cruciate Ligament Tears: A PLUTO Study Group Reliability Study.

BACKGROUND: Radiographic measurements of limb alignment in skeletally immature patients with anterior cruciate ligament (ACL) tears are frequently used for surgical decision-making, preoperative planning, and postoperative monitoring of skeletal growth. However, the interrater and intrarater reliability of these radiographic characteristics in this patient population is not well documented. HYPOTHESIS: Excellent reliability across 4 raters will be demonstrated for all digital measures of length, coronal plane joint orientation angles, mechanical axis, and tibial slope in skeletally immature patients with ACL tears. STUDY DESIGN: Cohort study (diagnosis). METHODS: Three fellowship-trained orthopaedic surgeons and 1 medical student performed 2 rounds of radiographic measurements on digital imaging (lateral knee radiographs and long-leg radiographs) of skeletally immature patients with ACL tears. Intrarater and interrater reliability for continuous radiographic measurements was assessed with intraclass correlation coefficients (ICCs) across 4 raters with 95% CIs for affected and unaffected side measurements. Interrater reliability analysis used an ICC (2, 4) structure and intrarater reliability analysis used an ICC (2, 1) structure. A weighted kappa coefficient was calculated for ordinal variables along with 95% CIs for both interrater and intrarater reliability. Agreement statistic interpretations are based on scales described by Fleiss, and Cicchetti and Sparrow: <0.40, poor; 0.40 to 0.59, fair; 0.60 to 0.74, good; and >0.74, excellent. RESULTS: Radiographs from a convenience sample of 43 patients were included. Intrarater reliability was excellent for nearly all measurements and raters. Interrater reliability was also excellent for nearly all reads for all measurements. CONCLUSION: Radiographic reliability of long-leg radiographs and lateral knee x-rays in skeletally immature children with ACL tears is excellent across nearly all measures and raters and can be obtained and interpreted as reliable and reproducible means to measure limb length and alignment.

Improved epiphyseal socket placement with intraoperative 3D fluoroscopy: a consecutive series of pediatric all-epiphyseal anterior cruciate ligament reconstruction.

PURPOSE: Disturbance of the growth plate during all-epiphyseal anterior cruciate ligament reconstruction (ACLR) socket placement is possible due to the undulation of the distal femoral physis and proximal tibial physis. Therefore, it is important to obtain intraoperative imaging of the guide wire prior to reaming the socket. The purpose of this study was to investigate the effect of the use of 3D intraoperative fluoroscopy on socket placement in patients undergoing all-epiphyseal ACLR. It was hypothesized that 3D imaging would allow for more accurate intraoperative visualization of the growth plate and hence a lower incidence of growth plate violation compared to 2D imaging. METHODS: Patients under the age of 18 who underwent a primary all-epiphyseal ACL reconstruction by the senior authors and had an available postoperative MRI were retrospectively reviewed. Demographic data, surgical details, and the distances between the femoral socket and distal femoral physis (DFP) and tibial socket and proximal tibial physis (PTP) were recorded. Patients were split into two groups based on type of intraoperative fluoroscopy used: a 2D group and a 3D group. Interrater reliability of radiographic measurements was evaluated using intraclass correlation coefficient (ICC). RESULTS: Seventy-two patients fit the inclusion criteria and were retrospectively reviewed. 54 patients had 2D imaging and 18 patients had 3D imaging. The mean age at time of surgery was 12.3 ± 1.5 years, 79% of patients were male, and 54% tore their left ACL. The mean time from surgery to postoperative MRI was 2.0 ± 1.1 years. The ICC was 0.92 (95% CI 0.35-0.98), indicating almost perfect interrater reliability. The mean difference in distance between the tibial socket and the PTP was significantly less in the 2D imaging group than the 3D imaging group (1.2 ± 1.7 mm vs 2.5 ± 2.2 mm, p = 0.03). The femoral and tibial sockets touched or extended beyond the DFP or PTP, respectively, significantly less in the 3D group than in the 2D group (11% vs 43%, p < 0.000, 17% vs 65%, p < 0.000). CONCLUSION: There was a significantly increased distance from the PTP and decreased incidence of DFP violation with use of 3D intraoperative imaging for all-epiphyseal ACLR socket placement. Surgeons should consider utilizing 3D imaging prior to creating femoral and tibial sockets to potentially decrease the risk of physis violation in these patients. LEVEL OF EVIDENCE: III.

Minimum 15-year follow-up for clinical outcomes of arthroscopic rotator cuff repair.

BACKGROUND AND HYPOTHESIS: Arthroscopic rotator cuff repair surgery is one of the most common shoulder procedures performed in the United States. Although several studies have shown considerable symptomatic relief in the short term following surgery, a relatively high rate of recurrent defects has led surgeons to question the long-term durability of this operation. We hypothesized that outcomes at a minimum of 15 years of follow-up in patients who underwent all-arthroscopic rotator cuff repair would be maintained and would remain significantly improved compared with the preoperative status. METHODS: All-arthroscopic rotator cuff repairs were performed in 193 patients from 2003 to 2005. Patient-reported outcomes were collected preoperatively and at 1, 2, 5, and ≥15 years postoperatively. The primary outcome was the American Shoulder and Elbow Surgeons (ASES) score. Secondary outcomes included Single Assessment Numeric Evaluation (SANE), Shoulder Activity Scale (SAS), visual analog scale, and Patient-Reported Outcomes Measurement Information System (PROMIS)-Upper Extremity (UE) scores. Patient demographic characteristics, revision surgical procedures, and complications were recorded. Generalized estimating equations were used to model scores over time, and multiple comparisons between time points were performed using Tukey adjustment. RESULTS: This study included 60 patients with a mean follow-up period of 16.5 years (range, 15.8-17.7 years). The mean ASES score improved from 60.2 ± 18.8 preoperatively to 93.0 ± 9.4 at ≥15 years (P < .0001). The mean visual analog scale pain score decreased from 4.1 ± 0.7 preoperatively to 0.7 ± 0.3 at ≥15 years (P < .0001). The average SANE, SAS, and PROMIS-UE scores at ≥15 years were 87.8 ± 14.8, 8.8 ± 4.3, and 49.6 ± 10.2, respectively. Of 60 patients, 7 underwent revision surgery. Older age and female sex were associated with lower SAS scores at 15 years, whereas female sex was associated with lower PROMIS-UE scores. There were no factors predictive of ASES or SANE scores. CONCLUSION: At long-term follow-up (≥15 years), the patient-reported outcomes of all-arthroscopic rotator cuff repair show significant improvement from baseline preoperative function and remain durable over a period of 15 years. This information is useful in counseling patients regarding the long-term results of this procedure.

Arthroscopic-Assisted Coracoclavicular Ligament Reconstruction: Clinical Outcomes and Return to Activity at Mean 6-Year Follow-Up.

PURPOSE: To report clinical and functional outcomes including return to preinjury activity level following arthroscopic-assisted coracoclavicular (CC) ligament reconstruction (AA-CCR) and to determine associations between return to preinjury activity level, radiographic outcomes, and patient-reported outcomes following AA-CCR. METHODS: A institutional registry review of all AA-CCR using free tendon grafts from 2007 to 2016 was performed. Clinical assessment included Single Assessment Numeric Evaluation (SANE) score and return to preinjury activity level at final follow-up. Treatment failure was defined as (1) revision acromioclavicular stabilization surgery, (2) unable to return to preinjury activity level, or (3) radiographic loss of reduction (RLOR, >25% CC distance compared with contralateral side). SANE scores, return to activity, and RLOR were compared between patients within each category of treatment failure, by grade of injury, and whether concomitant pathology was treated. RESULTS: There were 88 patients (89.8% male) with mean age of 39.6 years and minimum 2-year clinical follow-up (mean 6.1 years). Most injuries were Rockwood grade V (63.6%). Mean postoperative SANE score was 86.3 ± 17.5. Treatment failure occurred in 17.1%: 8.0% were unable to return to activity, 5.7% had RLOR, and 3.4% underwent revision surgery due to traumatic reinjury. SANE score was lower among patients who were unable to return to activity compared with those with RLOR and compared with nonfailures (P = .0002). There were no differences in revision surgery rates, return to activity, or SANE scores according to Rockwood grade or if concomitant pathology was treated. CONCLUSIONS: AA-CCR with free tendon grafts resulted in good clinical outcomes and a high rate of return to preinjury activity level. RLOR did not correlate with return to preinjury activity level. Concomitant pathology that required treatment did not adversely affect outcomes. Return to preinjury activity level may be a more clinically relevant outcome measure than radiographic maintenance of acromioclavicular joint reduction. LEVEL OF EVIDENCE: IV (Case Series).

Consensus statement on the treatment of massive irreparable rotator cuff tears: a Delphi approach by the Neer Circle of the American Shoulder and Elbow Surgeons.

BACKGROUND: Management of massive irreparable rotator cuff tears (MIRCTs) remains controversial owing to variability in patient features and outcomes contributing to a lack of unanimity in treatment recommendations. The purpose of this study was to implement the Delphi process using experts from the Neer Circle of the American Shoulder and Elbow Surgeons to determine areas of consensus regarding treatment options for a variety of MIRCTs. METHODS: A panel of 120 shoulder surgeons were sent a survey regarding MIRCT treatments including arthroscopic débridement and partial cuff repair, graft augmentation, reverse shoulder arthroplasty (RSA), superior capsular reconstruction (SCR), and tendon transfer. An iterative Delphi process was then conducted with a first-round questionnaire consisting of 13 patient factors with the option for open-ended responses to identify important features influencing the treatment of MIRCTs. The second-round survey sought to determine the importance of patient factors related to the 6 included treatment options. A third-round survey asked participants to classify treatment options for 60 MIRCT patient scenarios as either preferred treatment, acceptable treatment, not acceptable/contraindicated, or unsure/no opinion. Patient scenarios were declared to achieve consensus for the preferred and not acceptable/contraindicated categories when at least 80% of the survey respondents agreed on a response, and a 90% threshold was required for the acceptable treatment category, defined by an acceptable treatment or preferred treatment response. RESULTS: Seventy-two members agreed to participate and were deemed to have the requisite expertise to contribute based on their survey responses regarding clinical practice and patient volume. There were 20 clinical scenarios that reached 90% consensus as an acceptable treatment, with RSA selected for 18 scenarios and arthroscopic débridement and/or partial repair selected for 2. RSA was selected as the singular preferred treatment option in 8 scenarios. Not acceptable/contraindicated treatment options reached consensus in 8 scenarios, of which, 4 related to SCR, 3 related to RSA, and 1 related to partial repair with graft augmentation. CONCLUSION: This Delphi process exhibited significant consensus regarding RSA as a preferred treatment strategy in older patients with pseudoparesis, an irreparable subscapularis, and dynamic instability. In addition, the process identified certain unacceptable treatments for MIRCTs such as SCR in older patients with pseudoparesis and an irreparable subscapularis or RSA in young patients with an intact or reparable subscapularis without pseudoparesis or dynamic instability. The publication of these scenarios and areas of consensus may serve as a useful guide for practitioners in the management of MIRCTs.

Isolated tears of the sternocostal head of the pectoralis major muscle: surgical technique, clinical outcomes, and a modification of the Tietjen and Bak classification.

HYPOTHESIS: We aimed to describe a modified surgical technique to treat isolated sternocostal head tears using cortical button fixation while preserving the intact clavicular head tendon, to outline a new classification of pectoralis major injuries, and to present the clinical outcomes and return-to-sport data of a cohort of 21 athletes who underwent surgical repair. METHODS: We reviewed prospectively collected data of patients who underwent surgical repair with the described technique for isolated sternocostal head tears from 2008 to 2014. Two-year postoperative clinical outcomes including the Single Assessment Numeric Evaluation score, isokinetic strength, patient satisfaction, and return to sport, as well as preinjury and postoperative bench-press weight, were collected, and descriptive statistics were used for analysis. RESULTS: Twenty-one patients who underwent repair of isolated sternocostal head tears were included. The majority of the isolated tears of the sternocostal head of the pectoralis major (57%) occurred during the bench press. Of the ruptures, 81% were Tietjen type IIIC and 19% were type IIID. Postoperative Single Assessment Numeric Evaluation scores averaged 90.1 (standard deviation, 8.4), and patient satisfaction was 9.5 of 10 (standard deviation, 0.9). All athletes returned to sport approximately 5.5 months postoperatively. The isokinetic strength deficit averaged 8% compared with the contralateral arm, whereas the average preinjury bench-press weight of 134 kg (range 88-227 kg) was restored to 117 kg (range 61-250 kg) postoperatively. CONCLUSION: We propose a new classification of pectoralis major injury. In addition, we present a biomechanically sound repair technique for isolated tears of the sternocostal head of the pectoralis with favorable outcomes. The technique takes the specific anatomy of the sternocostal and clavicular heads into account for the approach.

Arthroscopic shoulder stabilization in the young athlete: return to sport and revision stabilization rates.

BACKGROUND: Shoulder instability in young athletes is a complex problem with higher recurrence, higher reoperation, and lower return to sport (RTS) rates after arthroscopic shoulder stabilization compared with adults. METHODS: This is a prospective case series of young athletes with anterior shoulder instability after arthroscopic stabilization surgery. Primary outcomes were RTS and revision surgery, minimum follow-up was 24 months. Exclusion criteria were more than 3 preoperative episodes of instability, significant bone loss, or primary posterior instability. Demographic data, recurrent instability, revision surgery, sports pre- and postsurgery, patient satisfaction, level of RTS, time to RTS, and Single Assessment Numeric Evaluation (SANE) scores were analyzed. RESULTS: Sixty-seven athletes met inclusion criteria, 19 females and 48 males, with a mean age of 17.5 years (range, 13-21 years). Fifty-nine (88%) athletes returned to sport at an average of 7.1 months (standard deviation, ±1.8); 50 (75%) returned to the same level or higher. Football and lacrosse were the most common sports. Four of 67 athletes (6%), all male, underwent revision stabilization at 11-36 months for recurrent instability. The overall mean SANE score was 88. CONCLUSION: This study demonstrates that when the high-risk athlete, 21 years old or younger, is appropriately selected for arthroscopic shoulder stabilization by excluding those with 3 or more preoperative shoulder instability episodes and those with off-track and engaging instability patterns, excellent outcomes can be achieved with low revision surgery rates, high RTS rates, and high patient satisfaction.

Decision making in treatment after a first-time anterior glenohumeral dislocation: A Delphi approach by the Neer Circle of the American Shoulder and Elbow Surgeons.

BACKGROUND: The treatment of patients who sustain a first-time anterior glenohumeral dislocation (FTAGD) is controversial. The purpose of this study was to find consensus among experts using a validated iterative process in the treatment of patients after an FTAGD. METHODS: The Neer Circle is an organization of shoulder experts recognized for their service to the American Shoulder and Elbow Surgeons. Consensus among 72 identified experts from this group was sought with a series of surveys using the Delphi process. The first survey used open-ended questions designed to identify patient-related features that influence treatment decisions after an FTAGD. The second survey used a Likert scale to rank each feature's impact on treatment decisions. The third survey used highly impactful features to construct 162 clinical scenarios. For each scenario, experts recommended surgery or not and reported how strongly they made their recommendation. These data were analyzed to find clinical scenarios that had >90% consensus for recommending treatment. These data were also used in univariate and multivariate mixed-effects models to identify odds ratios (ORs) for different features and to assess how combining these features influenced the probability of surgery for specific populations. RESULTS: Of the 162 scenarios, 8 (5%) achieved >90% consensus for recommending surgery. All of these scenarios treated athletes with meaningful bone loss at the end of their season. In particular, for contact athletes aged > 14 years who were at the end of the season and had apprehension and meaningful bone loss, there was >90% consensus for recommending surgery after an FTAGD, with surgeons feeling very strongly about this recommendation. Of the scenarios, 22 (14%) reached >90% consensus for recommending nonoperative treatment. All of these scenarios lacked meaningful bone loss. In particular, surgeons felt very strongly about recommending nonoperative treatment after an FTAGD for non-athletes lacking apprehension without meaningful bone loss. The presence of meaningful bone loss (OR, 6.85; 95% confidence interval, 6.24-7.52) and apprehension (OR, 5.60; 95% confidence interval, 5.03-6.25) were the strongest predictors of surgery. When these 2 features were combined, profound effects increasing the probability of surgery for different populations (active-duty military, non-athletes, noncontact athletes, and contact athletes) were noted, particularly non-athletes. CONCLUSION: Consensus for recommending treatment of the FTAGD patient was not easily achieved. Certain combinations of patient-specific factors, such as the presence of meaningful bone loss and apprehension, increased the probability of surgery after an FTAGD in all populations. Over 90% of shoulder instability experts recommend surgery after an FTAGD for contact athletes aged > 14 years at the end of the season with both apprehension and meaningful bone loss. Over 90% of experts would not perform surgery after a first dislocation in patients who are not athletes and who lack apprehension without meaningful bone loss.

Electrodiagnostic evidence of suprascapular nerve recovery after decompression.

INTRODUCTION: The purpose of this study was to determine whether surgical arthroscopic decompression or ultrasound-guided aspiration of a paralabral cyst would result in suprascapular nerve recovery from axonal regeneration based on electrodiagnostic testing. METHODS: Nine patients with preoperative electromyography (EMG) evidence of suprascapular neuropathy due to paralabral cysts at the suprascapular or spinoglenoid notch were prospectively studied. Eight patients underwent arthroscopic surgical decompression, and 1 patient underwent ultrasound-guided aspiration. Postoperative EMG was performed in all patients to evaluate nerve regeneration. RESULTS: Three (33%) patients had cysts at the suprascapular notch, whereas 6 (67%) patients had cysts at the spinoglenoid notch. All patients showed complete electrophysiological recovery after decompression. DISCUSSION: Decompression of paralabral cysts at the suprascapular or spinoglenoid notch resulted in postoperative EMG evidence of nerve recovery. Long-term studies with a greater number of patients are required to elucidate time to recovery. Muscle Nerve 59:247-249, 2019.

PROMIS physical function underperforms psychometrically relative to American Shoulder and Elbow Surgeons score in patients undergoing anatomic total shoulder arthroplasty.

BACKGROUND: The purpose of this study was to evaluate the psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function computer adaptive test (PF-CAT) relative to the American Shoulder and Elbow Surgeons (ASES) score in patients with glenohumeral osteoarthritis undergoing primary anatomic total shoulder arthroplasty (TSA). METHODS: A retrospective study of an institutional TSA registry was performed. Preoperative PROMIS PF-CAT and ASES scores were collected. Floor and ceiling effects were determined, and convergent validity was established through Pearson correlations. Rasch partial credit modeling was used for psychometric analysis of the validity of PF-CAT and ASES question items. Person-item maps were generated to characterize the distribution of question responses along the latent dimension of shoulder disability. RESULTS: Responses from 179 patients (184 shoulders) were included. PF-CAT had a moderate correlation to ASES (r = 0.487; P < .001), with no floor or ceiling effects; ASES had a 1.1% floor effect and no ceiling effect. With iterative Rasch model item-reduction analysis eliminating poorly fitting question items, all possible PF-CAT items were eliminated after 6 iterations. With ASES, just 1 function question item was dropped. Person-item maps showed ASES to be superior to PROMIS PF-CAT psychometrically, with sequential and improved coverage of the latent dimension of shoulder disability. CONCLUSION: Despite moderate correlation with ASES, PROMIS PF-CAT demonstrated inferior validity and psychometric properties in patients undergoing TSA. PF-CAT should not replace the ASES in this population of patients.

A prospective study assessing the political advocacy of American Shoulder and Elbow Surgeons members.

BACKGROUND: This study assessed the current political standings and active political engagement of American Shoulder and Elbow Surgeons (ASES) members along with the political process as it relates to health care policy. METHODS: This survey study involved 552 ASES members. The survey was open for 2 weeks. Responses were received from 254 of the 552 members (46%), and their answers were analyzed. RESULTS: Six (2%) of the responding members were solo practitioners, 100 (39%) belonged to a private practice, 106 (42%) were providers at academic institutions or residency training programs, 25 (10%) were employed by a hospital, and 17 (7%) categorized themselves as other. Email was the preferred method of communication. Of all responding members, 110 (43%) stated they had contributed to the American Academy of Orthopaedic Surgery Political Advocacy Committee in the last 12 months. Four (10%) of the responding members have a relationship with an elected official, and 220 (87%) would be willing to become a key contact and reach out to a legislator. CONCLUSION: Moving forward, this survey can be used to better shape the political advocacy efforts of the ASES and potentially other subspecialty societies. The response that "a high percentage of members would like to be more involved" suggests the need for a program to help further educate and facilitate the membership on political advocacy.

Editorial Commentary: The Partial Thickness Rotator Cuff Tear: Is Acromioplasty Without Repair Ever Indicated?

I believe that arthroscopic repair is the treatment of choice for patients with partial thickness rotator cuff tears when nonoperative methods have been exhausted. Excluding overhead athletes and patients in whom long head biceps tendon pathology is the primary concern, I do not believe that a significant role exists for debridement with or without acromioplasty in the majority of patients with partial thickness tears. Regarding the repair technique, I prefer in situ repair for bursal-sided tears because the superior capsule is intact and completion of the tear with repair for articular-sided tears.

Editorial Commentary: The All-Epiphyseal Anterior Cruciate Ligament Distal Femoral Approach: Sockets or Tunnels?

I believe that the distal femoral approach for anterior cruciate ligament reconstruction in the skeletally immature athlete with 3 to 6 years of remaining growth is best performed with an all-inside, all-epiphyseal technique using sockets rather than an outside-in approach creating tunnels. A shorter socket rather than a longer tunnel exposes a smaller surface area of the lateral distal femoral physis to potential compromise and resultant valgus malalignment. In addition, exiting the lateral femoral aspect of the epiphysis with a full-diameter tunnel as compared with a smaller diameter drill hole used to prepare a socket places the posterior articular cartilage, the lateral collateral ligament and anterolateral ligament footprints, and the popliteus tendon insertion at risk. My preference for sockets is also related to my belief that they provide a superior biologic milieu for graft incorporation compared with a full-length tunnel with the attendant violation of the lateral femoral cortex of the epiphysis.

Physical exam of the adolescent shoulder: tips for evaluating and diagnosing common shoulder disorders in the adolescent athlete.

PURPOSE OF REVIEW: In the young athlete, the shoulder is one of the most frequently injured joints during sports activities. The injuries are either from an acute traumatic event or overuse. Shoulder examination can present some challenges; given the multiple joints involved, the difficulty palpating the underlying structures, and the potential to have both intra- and/or extra-articular problems. RECENT FINDINGS: Many of the shoulder examination tests can be positive in multiple problems. They usually have high sensitivity but low specificity and therefore low predictive value. The medical history coupled with a detailed physical exam can usually provide the information necessary to obtain an accurate diagnosis. A proficient shoulder examination and the development of an adequate differential diagnosis are important before considering advanced imaging. SUMMARY: The shoulder complex relies upon the integrity of multiple structures for normal function. A detailed history is of paramount importance when evaluating young athletes with shoulder problems. A systematic physical examination is extremely important to guiding an accurate diagnosis. The patient's age and activity level are very important when considering the differential diagnosis. Findings obtain through history and physical examination should dictate the decision to obtain advanced imaging of the shoulder.

Nonmodifiable risk factors for anterior cruciate ligament injury.

PURPOSE OF REVIEW: As anterior cruciate ligament (ACL) injury is becoming increasingly prevalent in the population of active children and young adolescents, it is crucial to be aware of both the modifiable and nonmodifiable factors that place this population at increased ACL injury risk. Historically, there has not been a definitive consensus on all of these risk factors-particularly the nonmodifiable ones. RECENT FINDINGS: The present review has accumulated the most recent evidence for the nonmodifiable risk factors in ACL injury focusing particularly on female gender, generalized joint laxity, knee recurvatum, increased lateral tibial slope, decreased intercondylar notch width, structural lower extremity valgus, limb length discrepancy, family history, and history of contralateral knee ACL injury. SUMMARY: Physicians should be aware of the nonmodifiable risk factors for ACL tears in active children and adolescents and should also encourage avoidance of modifiable risk factors in this population. Young athletes with nonmodifiable risk factors are at a particularly increased risk of recurrent injury following ACL reconstruction (ACLR). We believe that a primary extra-articular augmentation via iliotibial band tenodesis at the same time of ACLR may decrease the rate of reinjury for the high risk athlete with multiple nonmodifiable risk factors.

Pectoralis major tendon tears: functional outcomes and return to sport in a consecutive series of 40 athletes.

BACKGROUND: There are limited data on the outcomes of surgically repaired pectoralis major tendon (PMT) tears. The purpose of this study was to report the functional outcomes, return to sport, and second surgery rates in a consecutive series of PMT tears. METHODS: Forty patients with acutely repaired PMT tears were retrospectively identified. Follow-up was conducted with functional outcome scores and adduction strength testing at final follow-up. Return to sport and incidence of subsequent surgery were also recorded. RESULTS: The average age of the patients was 34.4 years (range, 23-59 years). Average follow-up was 2.5 years (range, 2-7.0 years). Twenty-three injuries (58%) occurred in the nondominant extremity. Bench press (n = 26) and contact sport participation (n = 14) were the most common mechanisms. Postoperative Single Assessment Numeric Evaluation scores averaged 93.6 (range, 62-100), with patient satisfaction of 9.6 of 10 (range, 6-10). All athletes returned to preinjury level of function approximately 5.5 months postoperatively (range, 4.5-6.5 months); 23.1% and 2.6% described mild or moderate difficulties with sport participation. Isokinetic strength evaluation revealed an average decrease of 9.9% (range, -18% to 41%). Application of the Bak criteria revealed 37% excellent, 26% good, and 37% fair outcomes, with most in the fair group reporting cosmetic concerns. Removing cosmesis, 46% scored excellent, 37% good, and only 17% fair. Three athletes required a second surgical procedure (7.5%). CONCLUSIONS: Surgical repair of PMT tears resulted in high patient satisfaction, with excellent restoration of function and adduction strength, early return to sport, and few reoperations, albeit with the potential for mild cosmetic concerns.

Rupture of the short head component of a bifurcated distal biceps tendon.

BACKGROUND: Rupture of the short head component of a bifurcated distal biceps tendon is a rare injury that may be difficult to diagnose and to treat. METHODS: Three cases of patients with selective disruption of the short head of the biceps distal tendon from a single institution are reported. The presenting history, physical examination, imaging studies, operative findings, and treatment strategies are described. RESULTS: In each case, the mechanism of injury was forceful flexion of the involved elbow against an eccentric load. Notable physical examination findings included a palpable tendon in the antecubital fossa, a "reverse Popeye" deformity, and pain and weakness with resisted forearm supination and elbow flexion. Careful review of the magnetic resonance imaging studies demonstrated the classic findings for this unique injury. All 3 patients successfully returned to their baseline level of activity after anatomic repair of the short head component with or without independent repair of the long head component (depending on the degree of partial tearing seen intraoperatively). DISCUSSION/CONCLUSIONS: Rupture of the short head component of a bifurcated distal biceps tendon is a rare injury that can be easily misdiagnosed and mistreated. A meticulous physical examination and evaluation of imaging is required to differentiate this injury from a partial or complete tear of a common distal biceps tendon. Clinicians should maintain a high index of suspicion for this unusual injury pattern. When it is diagnosed appropriately, selective disruption of the short head of the biceps distal tendon may be effectively treated with anatomic repair.

Surgical options for anterior cruciate ligament reconstruction in the young child.

Injury to the anterior cruciate ligament (ACL) is becoming increasingly common in the skeletally immature population. Historically, there was a reluctance to operate on skeletally immature patients due to potential damage to the physis and subsequent growth disturbances; however, more recently, ACL reconstruction techniques specifically developed for this young population have shown good outcomes and low complication rates. In this article, we briefly discuss the modifiable and non-modifiable risk factors for ACL injury in children, options for conservative management for ACL rupture, and outcomes for delayed operative management. The main focus of the manuscript is to describe three operative technique options designed for ACL reconstruction in skeletally immature patients and to review the literature on outcomes and complications of these techniques. Two of these techniques, namely the Modified MacIntosh and the all-epiphyseal techniques, are often referred to as physeal-sparing, while the third, i.e. the transphyseal technique, is not. While different in approach and technique, these procedures have been shown to produce good outcomes and minimal complications in the skeletally immature population. Despite these positive reports, it is also essential to be aware of potential complications and the potential risk of recurrence.

Association of Lateral Extra-Articular Tenodesis With Improved Graft Maturity on MRI 2 Years After ACL Reconstruction With Quadriceps Tendon Autograft in Skeletally Immature Athletes.

Background: Quadriceps tendon autograft (QTA) has recently gained popularity in the treatment of anterior cruciate ligament (ACL) ruptures in pediatric patients. The addition of lateral extra-articular tenodesis (LET) to an ACL reconstruction (ACLR) has been found to reduce the risk of ACL retear in high-risk patients. Purpose: To (1) compare ACL graft maturity using signal intensity ratios (SIRs) on magnetic resonance imaging (MRI) scans in skeletally immature patients undergoing ACLR with QTA either with or without concomitant LET and (2) evaluate LET safety by calculating the physeal disturbance-related reoperation rate in the ACLR+LET group. Study Design: Cohort study; Level of evidence, 3. Methods: The records of patients aged ≤18 years who underwent ACLR between 2015 and 2021 were reviewed retrospectively. Patients undergoing ACLR with QTA who had open distal femoral and proximal tibial physes on MRI scans and a minimum 2-year follow-up data were included. SIR values were measured on sagittal MRI scans by averaging the signal at 3 regions of interest along the ACL graft and dividing by the signal of the posterior cruciate ligament at its insertion. Statistical analysis was performed to evaluate differences in SIR values at 6 months, 1 year, and 2 years postoperatively in patients who underwent ACLR alone versus ACLR+LET. Results: Overall, 29 patients were included in the study: 16 patients in the ACLR+LET group and 13 patients in the ACLR-only group. There were no significant differences in SIR values between groups at the 6-month or 1-year postoperative timepoints. At 2 years postoperatively, the median SIR of the ACLR+LET group was significantly lower than that of the ACLR-only group on both univariate (1.33 vs 1.86, respectively, P = .0012) and multivariate regression analyses adjusting for both sex and surgical technique (ß = -0.49 [95% CI, -0.91 to -0.05]; P = .029). There were no cases of reoperation for physeal disturbance in patients who underwent ACLR+LET. Conclusion: The addition of LET to an ACLR with QTA was associated with lower average SIR values and thus improved graft maturity at 2 years postoperatively compared with ACLR alone in skeletally immature patients. The addition of LET to an ACLR was found to be safe in skeletally immature patients.
