Abstract
Background Malpositioning of the femoral button is a known technical complication after anterior cruciate ligament (ACL) reconstruction with cortical suspensory fixation. The incidence of malpositioning, as well as the efficacy of methods to prevent malpositioning of cortical suspensory fixation devices, has not been reported. Purpose To determine the rate of malpositioned cortical suspensory fixation devices after ACL reconstruction, investigate which intraoperative technique yields the lowest rate of malpositioning, and determine the return-to-duty rate for active-duty service members with malpositioned buttons and the revision rate for malpositioned buttons. Study Design Case series; Level of evidence, 4. Methods The records of patients who underwent primary ACL reconstruction with a cortical suspensory fixation device between 2008 and 2018 were reviewed at our institution. Postoperative radiographs were reviewed for evidence of malpositioned femoral buttons. Malpositioned buttons were classified as (1) fully positioned in the bone tunnel, (2) partially positioned in the bone tunnel, (3) >2 mm from cortical bone, or (4) deployed over the iliotibial band. Operative reports were reviewed to determine the intraoperative methods undertaken to verify the button position. The rate of malpositioned cases with subjective instability and revision surgery performed were determined. The ability of patients to return to full military duty was reviewed for active-duty personnel. Results A total of 1214 patients met the inclusion criteria. A 3.5% rate (42 cases) of malpositioned cortical suspensory fixation devices (femoral buttons) was identified. For patients with malpositioned buttons, 7 (16.7%) patients underwent revision surgery in the immediate postoperative period. Techniques used to avoid malpositioning included direct arthroscopic visualization, direct open visualization, intraoperative fluoroscopy, and first passing the button through the skin before positioning on the femoral cortex. There was a 4.6% malposition rate using direct arthroscopic visualization and a 5.1% malposition rate using passage of the button through the skin, while no malpositioning occurred with intraoperative fluoroscopy or direct open visualization (P < .05). Overall, 12 (28.6%) patients with malpositioned buttons ultimately underwent revision surgery. Despite having been diagnosed with malpositioned buttons, 21 (63.6%) active-duty members were able to return to full duty. Conclusion Malpositioning of femoral buttons during ACL reconstruction occurred in 3.5% of patients in this series. The techniques of intraoperative fluoroscopy and direct open visualization are encouraged to prevent malpositioning.

Abstract
Background Anterior cruciate ligament (ACL) repair had previously been considered the standard of care for a ruptured ACL; however, ACL reconstruction has became the standard of care because of poor midterm outcomes after ACL repair. Recently, studies have suggested that the treatment paradigm should shift back to ACL repair. Purpose/Hypothesis The purpose of this study was to evaluate the outcomes of ACL repair augmented with suture tape in a high-demand military population. We hypothesized that for proximal ACL avulsions, ACL repair with suture tape augmentation would lead to acceptable failure rates, satisfactory knee stability, excellent functional outcomes, and high rates of return to preinjury activity levels. Study Design Case series; Level of evidence, 2. Methods Patients who were treated with ACL repair by a single surgeon between March 2017 and June 2019 and who had a minimum of 2 years of follow-up were included. Intraoperatively, all patients first underwent an arthroscopic examination. If an ACL avulsion of the proximal insertion with adequate remaining tissue was visualized, then ACL repair was performed. The primary outcome assessed was ACL repair failure, defined as reruptures or clinical instability requiring revision to ACL reconstruction. Analysis of the risk factors for ACL repair failure was conducted, with age at surgery, sex, body mass index, level of competition, and tobacco use evaluated. Results Included were 46 patients (32 male and 14 female; mean age, 28.3 ± 8.4 years) who underwent ACL repair with suture tape augmentation. There were 12 cases of failure (26.1%; 8 male and 4 female). The mean time from injury to surgery in the failure group was 164.1 ± 59.4 days compared to 107.3 ± 98.0 days in the nonfailure group (P = .02). According to multivariate regression analysis, patients aged ≤17 and ≥35 years, elite/competitive/operational patients, and current smokers had a higher chance of ACL repair failure. The mean time to pass a military physical fitness test was 5.0 months. There were no complications other than ACL repair failure. Conclusion Primary arthroscopic ACL repair with suture tape augmentation resulted in unacceptably high failure rates at a minimum of 2 years of follow-up in a highly active military population. Age ≤17 and ≥35 years, elite level of competition, time from injury to surgery, and active tobacco use were independent risk factors for ACL repair failure.

Abstract
INTRODUCTION Anterior cruciate ligament (ACL) reconstruction failure remains a commonly seen complication despite advances in technique and graft options. Recently, several studies have shown that the inclination of the tibial plateau in the sagittal plane affects the stability of the knee joint. The purpose of this study was to determine if an increased posterior slope of the tibia is associated with failure of ACL reconstruction irrespective of the graft used. METHODS From June 2002 to August 2003, a total of 100 patients with a symptomatic ACL-deficient knee were randomised to receive either a hamstring autograft or posterior tibialis allograft. All allografts were from a single tissue bank, aseptically processed, and fresh-frozen without terminal irradiation. ACL graft failures requiring reoperation with a minimum of 10-year follow-up were identified via telephone survey. Lateral radiographs of the knee of all patients were reviewed, and the slope of the tibia was measured using a standardised technique. Two fellowship-trained orthopaedic sports medicine specialists, one board-certified general orthopaedic surgeon, and two fellowship-trained musculoskeletal radiologists measured the tibial slope in all patients. RESULTS At a minimum of 10-year follow-up, there were four (8.3%) autograft and 13 (26.5%) allograft failures that required revision reconstruction. The overall average tibial slope of the nonfailure cohort was 9.4°. The overall average tibial slope of the failure cohort was 11.9° (P = 0.0002). The average slope of the allograft failures was 11.5°compared with an average slope of 9.6° in the nonfailures (P = 0.01). The average slope of the autograft failures was 13.1° compared with 9.3° in the nonfailures (P = 0.011). The mean difference in tibial slope measurements was 0.665 (95% confidence interval: 0.569-0.750). The interrater reliability, as measured by the intraclass correlation coefficient, for tibial slope was 0.898 (95% confidence interval: 0.859-0.928). The Cronbach α was 0.904. CONCLUSION In a prospective, randomised trial of ACL reconstructions using either autograft or allograft, failures were associated with a significantly increased slope of the tibia compared with the nonfailures at 10-year follow-up.

Abstract
Distal hamstring injuries and tendon ruptures are rarer than their proximal counterparts, and literature on the management of these injuries is limited. We present a case report of an active-duty soldier who sustained an intratendinous rupture isolated to the long head of the biceps femoris, as well as a summary of the available evidence on this subject matter. A combined end-to-end repair with partial tenodesis to the intact short head allowed the patient a near-full return to military duties at 5 months postoperatively. Surgery combined with diligent, supervised rehabilitation may be effective in returning patients with intratendinous distal biceps femoris tendon tears to athletic lifestyles.

Abstract
Unicompartmental osteoarthritis in the young athlete poses a challenge for both patients and providers. Coronal plane malalignment is frequently a concomitant finding that adds to the complexity of management. Military surgeons are presented unique challenges, in that they must consider optimal joint-preservation methods while returning patients to a high-demand occupational function. Management options range from lifestyle changes to surgical interventions. We present a concise review of the available literature on this subject, with a specific focus on indications and outcomes within the military and young athletic population.

Abstract
INTRODUCTION The arthroscopic Bankart repair in the setting of glenoid bone loss has high rates of failure. In patients with anterior glenoid bone loss, the Latarjet provides glenohumeral stability through restoration of the glenoid bone, the conjoint tendon acting as a sling on the subscapularis, and anterior capsulolabral repair. Active-duty military personnel are at high risk for glenohumeral instability and have been equated to the contact athlete; most are young, male, and engage in contact sports. The purpose of this study is to assess the return to full-duty rates in active-duty military personnel following the Latarjet for anterior glenohumeral instability with glenoid bone loss. METHODS A retrospective review of all glenohumeral instability procedures were reviewed at a tertiary training hospital from June 2014 to June 2019. The patient population consisted of active-duty military personnel with glenoid bone loss and anterior glenohumeral instability, who were treated with a Latarjet. The primary outcome was return to full-duty status. RESULTS There were 50 patients identified for the study. Four patients were lost to follow-up, leaving 46 of 50 patients (92.0%) eligible for this study. The average age at the time of the index procedure was 23.1 years. The average percentage bone loss was 18.4%. Forty-one patients (89.1%) were able to return to full-duty status. Four patients (8.7%) sustained a recurrent dislocation following the Latarjet; all 4 dislocations occurred during a combat deployment. Four patients (8.7%) reported episodes of subluxation without dislocation. Forty-one patients (89.1%) reported that their shoulders felt stable, and we found an average return to full duty at 5.3 months CONCLUSION: In our active-duty military cohort, we found an 8.7% rate of recurrent instability after a Latarjet procedure, and 41 patients (89.1%) were able to return to full-duty status. In conclusion, the Latarjet procedure in the active-duty military population with anterior glenoid bone loss resulted in a high rate of return to duty, excellent functional outcomes, low rate of recurrent instability, and a low overall complication rate.

Abstract
Background: Few studies have reported the long-term outcomes of patellar stabilization surgery in an active duty military cohort. Purpose: To evaluate the long-term results of a combined open and arthroscopic patellar stabilization technique for the treatment of recurrent lateral patellar instability in members of a military population. Study Design: Case series; Level of evidence, 4. Methods: We performed a retrospective review of a consecutive series of 63 patients who underwent operative management for patellar instability at a tertiary military medical center between 2003 and 2017. All cases were performed by a single sports medicine fellowship–trained orthopaedic surgeon. Patients with recurrent lateral patellar instability whose nonoperative management failed were included. All patients underwent arthroscopic imbrication of the medial patellar retinaculum, an open lateral retinacular release, and an Elmslie-Trillat tibial tubercle osteotomy. Outcome measures at final follow-up included recurrent instability, need for surgical revision, subjective assessments, and military-specific metrics. We also analyzed anatomic risk factors for failure: patella alta, coronal plane alignment, trochlear dysplasia, and tibial tubercle–trochlear groove distance. Results: A total of 51 patients were included (34 men, 17 women; mean ± SD age at surgery, 27.2 ± 5.8 years; mean follow-up, 5.3 years). The mean postoperative SANE score (Single Assessment Numeric Evaluation) was 75.0 ± 17.7, and the mean visual analog scale pain score was 2.5 ± 2.1. Four patients (7.8%) reported redislocation events, and 4 underwent revision surgery. Twenty-five patients (49.0%) reported a decrease in activity level as compared with preinjury, while 10 (19.6%) cited restrictions in activities of daily living. Of the 21 patients remaining on active duty, 6 (28.6%) required an activity-limiting medical profile. Of the 48 active duty patients, 12 (25.0%) underwent evaluation by a medical board for separation from the military. Differences in the Caton-Deschamps Index and tibial tubercle–trochlear groove distance between surgical success and failure were not statistically significant. Conclusion: Surgical management of patellar instability utilizing a multifaceted technique resulted in low recurrence rates and may be independent of predisposing anatomic risk factors for instability. At 5-year follow-up, most patients retained their active duty status, although nearly half experienced a decrease in activity level.

Abstract
BACKGROUND Recent studies have demonstrated equivalent short-term results when comparing arthroscopic versus open anterior shoulder stabilization. However, none have evaluated the long-term clinical outcomes of patients after arthroscopic or open anterior shoulder stabilization, with inclusion of an assessment of preoperative glenoid tracking. PURPOSE To compare long-term clinical outcomes of patients with recurrent anterior shoulder instability randomized to open and arthroscopic stabilization groups. Additionally, preoperative magnetic resonance imaging (MRI) studies were used to assess whether the shoulders were "on-track" or "off-track" to ascertain a prediction of increased failure risk. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Follow-up assessments were performed at minimum 15-year follow-up using established postoperative evaluations. Clinical failure was defined as any recurrent dislocation postoperatively or subjective instability. Preoperative MRI scans were obtained to calculate the glenoid track and designate shoulders as on-track or off-track. These results were then correlated with the patients' clinical results at their latest follow-up. RESULTS Of 64 patients, 60 (28 arthroscopic and 32 open) were contacted or examined for follow-up (range, 15-17 years). The mean age at the time of surgery was 25 years (range, 19-42 years), while the mean age at the time of this assessment was 40 years (range, 34-57 years). The rates of arthroscopic and open long-term failure were 14.3% (4/28) and 12.5% (4/32), respectively. There were no differences in subjective shoulder outcome scores between the treatment groups. Of the 56 shoulders, with available MRI studies, 8 (14.3%) were determined to be off-track. Of these 8 shoulders, there were 2 surgical failures (25.0%; 1 treated arthroscopically, 1 treated open). In the on-track group, 6 of 48 had failed surgery (12.5%; 3 open, 3 arthroscopic [P = .280]). CONCLUSION Long-term clinical outcomes were comparable at 15 years postoperatively between the arthroscopic and open stabilization groups. The presence of an off-track lesion may be associated with a higher rate of recurrent instability in both cohorts at long-term follow-up; however, this study was underpowered to verify this situation.

Abstract
Background: Anterior cruciate ligament (ACL) reconstruction (ACLR) using bone-tendon-bone (BTB) autograft is associated with increased postoperative anterior knee pain and pain with kneeling and has the risk of intra- and postoperative patellar fracture. Additionally, graft-tunnel mismatch is problematic, often leading to inadequate osseous fixation. Given the disadvantages of BTB, an alternative is a bone-tendon autograft (BTA) procedure that has been developed at our institution. BTA is a patellar tendon autograft with the single bone plug taken from the tibia. Purpose/Hypothesis: The purpose of this study was to evaluate the short-term outcomes of BTA ACLR. We hypothesized that this procedure will provide noninferior failure rates and clinical outcomes when compared with a BTB autograft, as well as a lower incidence of anterior knee pain, pain with kneeling, and patellar fracture. Methods: A consecutive series of 52 patients treated with BTA ACLR were retrospectively identified and compared with 50 age-matched patients who underwent BTB ACLR. The primary outcome was ACL graft failure, while secondary outcomes included subjective instability, anterior knee pain, kneeling pain, and functional outcome scores (Single Assessment Numeric Evaluation, Lysholm, and International Knee Documentation Committee subjective knee form). Results: At a mean follow-up of 29.3 months after surgery, there were 2 reruptures in the BTA cohort (4.0%) and 2 in the BTB cohort (4.0%). In the BTA group, 18% of patients reported anterior knee pain versus 36% of the BTB group (P = .04). A total of 22% of patients noted pain or pressure with kneeling in the BTA cohort, as opposed to 48% in the BTB cohort (P = .006). There were no differences in functional scores. In the BTA group, 94.2% of patients reported that their knees subjectively felt stable, as compared with 86% in the BTB group (P = .18). Conclusion: This study demonstrated that the BTA ACLR leads to similarly low rates of ACL graft failure requiring revision surgery, with significantly decreased anterior knee pain and kneeling pain when compared with a BTB. Additionally, the potential complications of graft-tunnel mismatch and patellar fracture are eliminated with the BTA ACLR technique.

Abstract
The bone-tendon-bone (BTB) autograft is widely used for anterior cruciate ligament (ACL) reconstruction. However, the primary disadvantages of this technique include postoperative kneeling pain, the risk of perioperative patellar fracture, and graft-tunnel mismatch. Therefore, a single bone plug technique for ACL reconstructions was developed to mitigate the disadvantages of the BTB technique. To differentiate this graft, we have coined the term BTA, for bone-tendon-autograft. The middle third of the patellar tendon is used with a typical width of 10 to 11 mm. A standard tibial tubercle bone plug is harvested. The length of the patellar tendon and graft construct is then measured. If the tendon is >45 mm and the construct at least 70 mm, then we proceed with the BTA technique. At the inferior pole of the patella, electrocautery is used to harvest the tendon from the patella. The advantages of this technique include faster graft harvest and preparation. Obviating the patellar bone plug harvest should eliminate the risk of perioperative patellar fracture and theoretically will mitigate donor site morbidity and kneeling pain, 2 of the most commonly cited complications of the use of BTB autografts for ACL reconstruction. In conclusion, the BTA technique is a reliable technique for ACL reconstruction.

Abstract
Techniques for reconstruction of posterior cruciate ligament (PCL) tears are rapidly evolving. One problem with current techniques is that laxity may develop early in the postoperative period, leading to relapsed posterior translation of the tibia. Therefore, maintaining tibial reduction during graft incorporation is a target for improvement. We describe using an internal splint to optimize the 4-tunnel, double-bundle allograft PCL reconstruction.

Abstract
Background: Optimal timing of anterior cruciate ligament (ACL) reconstruction has been a topic of controversy. Reconstruction has historically been delayed for at least 3 weeks, given previous studies reporting a high risk of postoperative arthrofibrosis and suboptimal clinical results. Purpose: To prospectively evaluate postoperative range of motion following acutely reconstructed ACLs with patellar tendon autograft. Study Design: Case series; Level of evidence, 4. Methods: Patients (age >18 years) who had ACL reconstruction as soon as possible after injury, regardless of the condition or preoperative range of motion of the injured knee, underwent reconstruction with patellar tendon autograft. An identical standard surgical technique and postoperative rehabilitation were employed for all patients. Postoperative assessment included active range of motion measurements with a goniometer. Subjective outcomes were assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS). Results: A total of 25 consecutive patients who met the inclusion criteria were enrolled. The mean age was 27.9 years (range, 20-48 years), and 19 were men. The time from injury to surgery was a mean 4.5 days (range, 1-9 days). The mean objective follow-up was 10.9 months (range, 3 days–19.4 months), and range of motion was regained at a mean 4.4 months (range, 1-9 months). Three meniscal repairs and 3 microfractures were performed concomitantly. There was 1 graft failure at 3 years postoperatively, noted at 50 months of subjective follow-up. There was no loss of extension >3° as compared with the contralateral knee in any patient. There was no loss of flexion >5° as compared with the contralateral knee in any patient who completed objective follow-up. The mean KOOS at final subjective follow-up was 82.8 (range, 57.7-98.8) at a mean 56.6 months postoperative (n = 14/24; range, 48-58 months). Conclusion: Excellent clinical results can be achieved following ACL reconstruction performed ≤9 days after injury with patellar tendon autograft. The authors found that early ACL reconstructions do not result in loss of motion or suboptimal clinical results as long as a rehabilitation protocol emphasizing extension and early range of motion is employed.

Abstract
The use of silver in various forms has been advocated for its antibacterial properties for centuries, because its toxicity to human cells is considerably lower than its toxicity to bacteria. The Greek historian Herodotus recounted how the king of Persia, before going to war, among his provisions included boiled water stored in flagons of silver, ostensibly to mitigate the risk of foodborne infections in his troops. Additionally, recent studies support the use of silver to generate an electrical stimulation for promotion of wound healing. These concepts have been combined in a proprietary postoperative dressing that is promoted to mitigate the risk of postoperative infections.

Abstract
BACKGROUND Glenoid bone loss is a well-accepted risk factor for failure after arthroscopic stabilization of anterior glenohumeral instability. Glenoid bone loss in posterior instability has been noted relative to its existence in posterior instability surgery. Its effect on outcomes after arthroscopic stabilization has not been specifically evaluated and reported. PURPOSE The purpose was to evaluate the presence of posterior glenoid bone loss in a series of patients who had undergone arthroscopic isolated stabilization of the posterior labrum. Bone loss was then correlated to return-to-duty rates, complications, and validated patient-reported outcomes. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS A retrospective review was conducted at a single military treatment facility over a 4-year period (2010-2013). Patients with primary posterior instability who underwent arthroscopic isolated posterior labral repair were included. Preoperative magnetic resonance imaging was used to calculate posterior glenoid bone loss using a standardized "perfect circle" technique. Demographics, return to duty, complications, and reoperations, as well as outcomes scores including the Single Assessment Numeric Evaluation and the Western Ontario Shoulder Instability Index (WOSI) scores, were obtained. Outcomes were analyzed across all patients based on percentage of posterior glenoid bone loss. Bone loss was then categorized as below or above the subcritical threshold of 13.5% to determine if bone loss effected outcomes similar to what has been shown in anterior instability. RESULTS There were 43 consecutive patients with primary, isolated posterior instability, and 32 (74.4%) completed WOSI scoring. Mean follow-up was 53.7 months (range, 25-82 months) The mean posterior glenoid bone loss was 7.3% (0%-21.5%). Ten of 32 patients (31%) had no appreciable bone loss. Bone loss exceeded 13.5% in 7 of 32 patients (22%), and 2 patients (6%) exceeded 20% bone loss. Return to full duty or activity was nearly 90% overall. However, those with >13.5%, subcritical glenoid bone loss, were statistically less likely to return to full duty (relative risk = 1.8), but outcomes scores, complications, and revision rates were otherwise not different in those with no or minimal bone loss versus those with more significant amounts. CONCLUSION Posterior glenoid bone loss has not previously been evaluated independently relative to patients with shoulder instability repairs. Sixty-nine percent of our patients had measurable bone loss, and 22% had greater than 13.5%, or above subcritical bone loss. While these patients were statistically less likely to return to full duty, the reoperation rate, complications, and patient-reported outcomes between groups were not different.

Abstract
Objectives: Resilience, which is a psychometric property related to “hardiness” or the ability to respond to challenging situations, is a recognized predictor in many outcomes’ domains. This has been studied extensively in stressful situations such as military returning from deployment, serious disease, and traumatic injury. To date however, no study has assessed the role of patient resiliency with respect to surgical outcome. The purpose of this study was to assess the role of preoperative resiliency as calculated by the Brief Resiliency Score (BRS) on relevant surgical outcomes, including the time required to return to full unrestricted activity following an arthroscopic Bankart repair. In addition the correlation between pre-operative BRS with post-operative BRS, post-operative Western Ontario Instability Index (WOSI), American Shoulder and Elbow (ASES) and Single Assessment Numeric Evaluation (SANE) scores was also assessed. Methods: This is a retrospective review of prospectively gathered data on 25 consecutive active duty military patients undergoing an arthroscopic Bankart repair for instability. The mean follow-up was 24.3 months (range, 23-27) as the primary outcome was return to unrestricted duty which occurs within the first year post-intervention. There were 24 males and 1 female. All patients were on unrestricted active military duty prior to injuring the operative shoulder. All patients completed BRS, WOSI, ASES, and SANE questionnaires prior to operative intervention. They then completed the same questionnaires at the most recent follow-up as well as an additional questionnaire on military duty status (unrestricted duty, limited duty, medical separation from the military). Patients were divided into low resiliency and high resiliency groups based on a score of <4.0 for low and ≥4.0 for high in the BRS, and their outcomes were compared. Results: All patients had been cleared for return to full-duty or were undergoing a medical separation at final follow-up. There were no differences between groups in demographics, glenoid bone loss, or glenoid track status. Pre-operative BRS was significantly correlated with time to return to full duty, need for medical separation from the military, post-operative WOSI, SANE and ASES scores and change between pre- and post-operative WOSI, ASES and SANE scores. Those patients with high resiliency returned to full duty significantly faster than the low resiliency group (4.4 v 6.7 months, p<0.01), had better post-operative WOSI (86.4% v 48.9%, p<0.01), SANE (92 v 72, p=0.03), ASES scores (91.5 v 67.6, p=0.03) and were 5 times less likely to be medically separated from the military (7.7% v 38.5%, p<0.01). Also, patients with high resiliency had significantly greater improvement comparing pre-operative to post-operative WOSI (44.8% v 20.3%, p=0.04), ASES (22.0 v 7.5, p=0.04) and SANE scores (2.5 v 1.3, p=0.01). There were no patients with a change between pre- and post-operative resiliency classification. Conclusion: Preoperative resiliency was highly predictive of the time required to return to full, unrestricted military duty. It was also predictive of post-operative subjective and objective outcomes as well as overall improvement between pre- and post-operative outcomes scores. Highly resilient patients were able to return to duty 2 months faster with significantly fewer requiring medical separation from the military than those lacking resiliency.

Abstract
BACKGROUND Glenoid and humeral bone loss are well-described risk factors for failure of arthroscopic shoulder stabilization. Recently, consideration of the interactions of these types of bone loss (bipolar bone loss) has been used to determine if a lesion is "on-track" or "off-track." The purpose of this study was to study the relationship of the glenoid track to the outcomes of arthroscopic Bankart reconstructions. METHODS Over a 2-year period, 57 shoulders that were treated with an isolated, primary arthroscopic Bankart reconstruction performed at a single facility were included in this study. The mean patient age was 25.5 years (range, 20 to 42 years) at the time of the surgical procedure, and the mean follow-up was 48.3 months (range, 23 to 58 months). Preoperative magnetic resonance imaging was used to determine glenoid bone loss and Hill-Sachs lesion size and location and to measure the glenoid track to classify the shoulders as on-track or off-track. Outcomes were assessed according to shoulder stability on examination and subjective outcome. RESULTS There were 10 recurrences (18%). Of the 49 on-track patients, 4 (8%) had treatment that failed compared with 6 (75%) of 8 off-track patients (p = 0.0001). Six (60%) of 10 patients with recurrence of instability were off-track compared with 2 (4%) of 47 patients in the stable group (p = 0.0001). The positive predictive value of an off-track measurement was 75% compared with 44% for the predictive value of glenoid bone loss of >20%. CONCLUSIONS The application of the glenoid track concept to our cohort was superior to using glenoid bone loss alone with regard to predicting postoperative stability. This method of assessment is encouraged as a routine part of the preoperative evaluation of all patients under consideration for arthroscopic anterior stabilization. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Humeral avulsion of the glenohumeral ligament (HAGL) is a lesion that has been recognized as a cause of recurrent shoulder instability. To our knowledge there are no reports of successful return to full function in young, competitive athletes or return to manual labor following nonoperative management of a HAGL lesion. A 26-year-old Navy SEAL was diagnosed with a HAGL injury, and associated traction injury of the axillary nerve as well as a partial tear of the rotator cuff. Operative intervention was recommended; however, due to issues with training and with inability to properly rehab with the axillary nerve injury, surgical plans were delayed. Interestingly, the patient demonstrated both clinical and radiographic magnetic resonance imaging healing of his lesion over an 18-month period. At 18 months the patient had returned to full active duty without pain or instability as a Navy SEAL.

Abstract
BACKGROUND The use of allografts for anterior cruciate ligament (ACL) reconstruction in young athletes is controversial. No long-term results have been published comparing tibialis posterior allografts to hamstring autografts. PURPOSE To evaluate the long-term results of primary ACL reconstruction using either an allograft or autograft. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS From June 2002 to August 2003, patients with a symptomatic ACL-deficient knee were randomized to receive either a hamstring autograft or tibialis posterior allograft. All allografts were from a single tissue bank, aseptically processed, and fresh-frozen without terminal irradiation. Graft fixation was identical in all knees. All patients followed the same postoperative rehabilitation protocol, which was blinded to the therapists. Preoperative and postoperative assessments were performed via examination and/or telephone and Internet-based questionnaire to ascertain the functional and subjective status using established knee metrics. The primary outcome measures were graft integrity, subjective knee stability, and functional status. RESULTS There were 99 patients (100 knees); 86 were men, and 95% were active-duty military. Both groups were similar in demographics and preoperative activity level. The mean and median ages of both groups were identical at 29 and 26 years, respectively. Concomitant meniscal and chondral pathologic abnormalities, microfracture, and meniscal repair performed at the time of reconstruction were similar in both groups. At a minimum of 10 years (range, 120-132 months) from surgery, 96 patients (97 knees) were contacted (2 patients were deceased, and 1 was unable to be located). There were 4 (8.3%) autograft and 13 (26.5%) allograft failures that required revision reconstruction. In the remaining patients whose graft was intact, there was no difference in the mean Single Assessment Numeric Evaluation, Tegner, or International Knee Documentation Committee scores. CONCLUSION At a minimum of 10 years after ACL reconstruction in a young athletic population, over 80% of all grafts were intact and had maintained stability. However, those patients who had an allograft failed at a rate over 3 times higher than those with an autograft.

Abstract
BACKGROUND Glenoid bone loss is a common finding in association with anterior shoulder instability. This loss has been identified as a predictor of failure after operative stabilization procedures. Historically, 20% to 25% has been accepted as the "critical" cutoff where glenoid bone loss should be addressed in a primary procedure. Few data are available, however, on lesser, "subcritical" amounts of bone loss (below the 20%-25% range) on functional outcomes and failure rates after primary arthroscopic stabilization for shoulder instability. PURPOSE To evaluate the effect of glenoid bone loss, especially in subcritical bone loss (below the 20%-25% range), on outcomes assessments and redislocation rates after an isolated arthroscopic Bankart repair for anterior shoulder instability. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Subjects were 72 consecutive anterior instability patients (73 shoulders) who underwent isolated anterior arthroscopic labral repair at a single military institution by 1 of 3 sports medicine fellowship-trained orthopaedic surgeons. Data were collected on demographics, the Western Ontario Shoulder Instability (WOSI) score, Single Assessment Numeric Evaluation (SANE) score, and failure rates. Failure was defined as recurrent dislocation. Glenoid bone loss was calculated via a standardized technique on preoperative imaging. The average bone loss across the group was calculated, and patients were divided into quartiles based on the percentage of glenoid bone loss. Outcomes were analyzed for the entire cohort, between the quartiles, and within each quartile. Outcomes were then further stratified between those sustaining a recurrence versus those who remained stable. RESULTS The mean age at surgery was 26.3 years (range, 20-42 years), and the mean follow-up was 48.3 months (range, 23-58 months). The cohort was divided into quartiles based on bone loss. Quartile 1 (n = 18) had a mean bone loss of 2.8% (range, 0%-7.1%), quartile 2 (n = 19) had 10.4% (range, 7.3%-13.5%), quartile 3 (n = 18) had 16.1% (range, 13.5%-19.8%), and quartile 4 (n = 18) had 24.5% (range, 20.0%-35.5%). The overall mean WOSI score was 756.8 (range, 0-2097). The mean WOSI score correlated with SANE scores and worsened as bone loss increased in each quartile. There were significant differences (P < .05) between quartile 1 (mean WOSI/SANE, 383.3/62.1) and quartile 2 (mean, 594.0/65.2), between quartile 2 and quartile 3 (mean, 839.5/52.0), and between quartile 3 and quartile 4 (mean, 1187.6/46.1). Additionally, between quartiles 2 and 3 (bone loss, 13.5%), the WOSI score increased to rates consistent with a poor clinical outcome. There was an overall failure rate of 12.3%. The percentage of glenoid bone loss was significantly higher among those repairs that failed versus those that remained stable (24.7% vs 12.8%, P < .01). There was no significant difference in failure rate between quartiles 1, 2, and 3, but there was a significant increase in failure (P < .05) between quartiles 1, 2, and 3 (7.3%) when compared with quartile 4 (27.8%). Notably, even when only those patients who did not sustain a recurrent dislocation were compared, bone loss was predictive of outcome as assessed by the WOSI score, with each quartile's increasing bone loss predictive of a worse functional outcome. CONCLUSION While critical bone loss has yet to be defined for arthroscopic Bankart reconstruction, our data indicate that "critical" bone loss should be lower than the 20% to 25% threshold often cited. In our population with a high level of mandatory activity, bone loss above 13.5% led to a clinically significant decrease in WOSI scores consistent with an unacceptable outcome, even in patients who did not sustain a recurrence of their instability.

Abstract
Objectives: Acromioclavicular (AC) joint injuries are common and constitute approximately 9% of all shoulder injuries. Traditionally Rockwood Types IV, V, and VI AC dislocations are indicated for surgery, type III dislocations are controversial, and type I and II are treated non-operatively. Our objective is to determine the success of non-operative treatment in Type V AC dislocations in active duty service members who must continue to do push-ups, pull-ups, bear weight, and wear ruck-sacks among other demanding activities requiring upper body strength in order to maintain current employment and lifestyle. Methods: A retrospective review was conducted using an automated search of electronic patient medical records from March 2007 through March 2012 for patients diagnosed with an AC dislocation in the Tripler Army Medical Center Department of Orthopedics. Patients were excluded who were not active military at the time of injury or who were tertiary referrals. Radiographs were reviewed and comparison was made to the contralateral shoulder. A Type V injury was defined as greater than 100% increase in the coracoclavicular distance compared to the contralateral side or greater than 2cm of displacement unilaterally. Acute repair was defined as repair within 90 days without a trial of conservative therapy. Failure of conservative therapy was defined as being unable to return to full duty. A good outcome was defined as a return to full duty without limitations. Results: 103 patients were identified with 60 patients having a bilateral shoulder films. Normal CC distances of the uninjured shoulder ranged from 4.3 mm to 18.66 mm with a mean of 9.09 mm and a standard deviation of 2.30 mm. 34 patients were Type V dislocations. 5 patients were tertiary referrals and were excluded. Acute surgical AC reconstruction was selected in 8 patients, initial conservative therapy in 21. In the conservative group: 11 patients (61%) returned to duty without surgery (average 97.8 days); 5 patients had delayed surgery and returned to full duty (average 135.2 days after surgery, 1 revision); 1 was medically separated for this injury; 1 was considered a failure and elected to change his career; and 3 patients were lost to follow up. In the acute surgical group: 6 patients returned to full duty in an average of 169.3 days after surgery(mean time to surgery 28.29 days) with 3 of those requiring revision surgery; 1 patient was lost to follow up, 1 patient failed to return to full duty. In the conservatively treated group, there was no association between failure rates and increase in CC distance or mm of displacement (p= 0.32 and 0.69 respectively). Conclusion: While numerous studies have evaluated the operative versus non-operative treatment of type III injuries in both a prospective and retrospective manner, no study to date has reported on the conservative treatment of type V AC dislocations. In this study we report on conservative treatment being successful in a majority of patients and that the average time to return to duty was not improved in an acute versus delayed surgical intervention. While more study is needed, this suggests that type V AC dislocations may be given a trial of conservative therapy. Secondarily we report on an increased range of the normal CC interspace (previously reported 1.1-1.3cm).

Abstract
Postsurgical evaluation of osteochondral allograft transplant surgery (OATS) of the distal femur most commonly utilizes radiographs or magnetic resonance imaging. This article proposes the utilization of computed tomography (CT) arthrography as an additional option, which allows clear assessment of articular congruity and osseous integration. A retrospective review was performed of 18 patients who underwent an OATS for distal femoral chondral lesions and obtained CT arthrograms postoperatively. CT arthrograms were evaluated for osseous integration and articular congruity. The average age and follow-up were 30.9 years and 4.3 years, respectively. Only 60% of patients were able to remain in the military postoperatively. The articular cartilage was smooth in eight (44.4%); complete bony integration was noted in eight (44.4%) patients. Neither articular congruity nor bony integration was associated with duty status at final follow-up. Although it allows excellent evaluation, similar to other modalities, CT arthrogram does not appear predictive of functional outcome.

Abstract
BACKGROUND Osteochondral allograft transplantation (OATS) is a treatment option that provides the ability to restore large areas of hyaline cartilage anatomy and structure without donor site morbidity and promising results have been reported in returning patients to some previous activities. However, no study has reported on the durability of return to activity in a setting where it is an occupational requirement. HYPOTHESIS Osteochondral allograft transplantation is less successful in returning patients to activity in a population in which physical fitness is a job requirement as opposed to a recreational goal. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective review was conducted of 38 consecutive OATS procedures performed at a single military institution by 1 of 4 sports medicine fellowship-trained orthopaedic surgeons. All patients were on active duty at the time of the index procedure, and data were collected on demographics, return to duty, Knee Injury and Osteoarthritis Outcome Score (KOOS), and ultimate effect on military duty. Success was defined as the ability to return to the preinjury military occupational specialty (MOS) with no duty-limiting restrictions. RESULTS The mean lesion size treated was 487.0 ± 178.7 mm(2). The overall rate of return to full duty was 28.9% (11/38). An additional 28.9% (11/38) were able to return to limited activity with permanent duty modifications. An alarming 42.1% (16/38) were unable to return to military activity because of their operative knee. When analyzed for return to sport, only 5.3% (2/38) of patients were able to return to their preinjury level. Eleven patients underwent concomitant procedures. Statistical power was maintained by analyzing data in aggregate for cases with versus without concomitant procedures. When the 11 undergoing concomitant procedures were removed from the data set, the rate of return to full activity was 33.3% (9/27), with 22.3% (6/27) returning to limited activity and 44.4% (12/27) unable to return to activity. In this subset, 7.4% (2/27) were able to return to a preinjury level of sport. The KOOS values were significantly higher in the full activity group when compared with the limited and no activity groups (P < .01). Branch of service was a significant predictor of outcome, with Marine Corps and Navy service members more likely to return to full activity compared with Army and Air Force members. A MOS of combat arms was a significant predictor of a poor outcome. All patients demonstrated postoperative healing of their grafts as documented in their medical chart, and no patient in the series required revision for problems with graft incorporation. CONCLUSION Osteochondral allograft transplantation for the treatment of large chondral defects in the knee met with disappointing results in an active-duty population and was even less reliable in returning this population to preinjury sport levels. Branch of service and occupational type predicted the return to duty, but other traditional predictors of outcome such as rank and years of service did not. The presence of concomitant procedures did not have an effect on outcome with respect to activity or sport level with the numbers available for analysis.

Abstract
BACKGROUND Modern techniques for the treatment of acromioclavicular (AC) joint dislocations have largely centered on free tendon graft reconstructions. Recent biomechanical studies have demonstrated that an anatomic reconstruction with 2 clavicular bone tunnels more closely matches the properties of native coracoclavicular (CC) ligaments than more traditional techniques. No study has analyzed tunnel position in regard to risk of early failure. PURPOSE To evaluate the effect of clavicular tunnel position in CC ligament reconstruction as a risk of early failure. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective review was performed of a consecutive series of CC ligament reconstructions performed with 2 clavicular bone tunnels and a free tendon graft. The population was largely a young, active-duty military group of patients. Radiographs were analyzed for the maintenance of reduction and location of clavicular bone tunnels using a picture archiving and communication system. The distance from the lateral border of the clavicle to the center of each bone tunnel was divided by the total clavicular length to establish a ratio. Medical records were reviewed for operative details and functional outcome. Failure was defined as loss of intraoperative reduction. RESULTS The overall failure rate was 28.6% (8/28) at an average of 7.4 weeks postoperatively. Comparison of bone tunnel position showed that medialized bone tunnels were a significant predictor for early loss of reduction for the conoid (a ratio of 0.292 vs 0.248; P = .012) and trapezoid bone tunnels (a ratio of 0.171 vs 0.128; P = .004); this correlated to an average of 7 to 9 mm more medial in the reconstructions that failed. Reconstructions performed with a conoid ratio of ≥0.30 were significantly more likely to fail (5/5, 100%) than were those performed lateral to a ratio of 0.30 (3/23, 13.0%) (P < .01). There were no failures when the conoid ratio was <0.25 (0/10, 0%). Conoid tunnel placement was also statistically significant for predicting return to duty in our active-duty population. CONCLUSION Medial tunnel placement is a significant factor in risk for early failures when performing anatomic CC ligament reconstructions. Preoperative templating is recommended to evaluate optimal placement of the clavicular bone tunnels. Placement of the conoid tunnel at 25% of the clavicular length from the lateral border of the clavicle is associated with a lower rate of lost reduction and a higher rate of return to military duty.

Abstract
INTRODUCTION Coracoclavicular (CC) ligament reconstruction remains a challenging procedure. The ideal reconstruction is biomechanically strong, allows direct visualization of passage around the coracoid, and is minimally invasive. Few published reports have evaluated arthroscopic techniques with a single clavicular tunnel and transcoracoid reconstruction. One such report noted early excellent results, but without specific outcome measures. This study reports the clinical and radiographic results of a minimally invasive, arthroscopically assisted technique of CC ligament reconstruction using a transcoracoid and single clavicular tunnel technique. MATERIALS AND METHODS A retrospective review was performed of 10 consecutive repairs in 9 active duty patients who underwent CC ligament reconstruction with the GraftRope (Arthrex, Naples FL, USA). All reconstructions were performed according to the manufacturer's technique by a single, fellowship-trained surgeon. Medical records and radiographs were evaluated for demographics, operative details, loss of reduction, and return to duty. RESULTS In 8 of 10 repairs (80%) intraoperative reduction was lost at an average of 7.0 weeks (range, 3-12 weeks). Four patients (40%) required revision. Subjective patient outcomes included 5 excellent/good results, 1 fair result, and 4 poor results. Tunnel widening was universally noted, and the failure mode in most patients appeared to be at the holding suture. CONCLUSION This transcoracoid, single clavicular tunnel technique was not a reliable approach to CC ligament reconstruction. We noted a high percentage of radiographic redisplacement and clinical failure. This technique, in its current form, cannot be recommended to treat AC joint injuries in our population.

Abstract
A 23-year-old male athlete reported both feeling and hearing a pop in his anterior thigh while sprinting. This was followed by immediate pain and an inability to walk. He had swelling and tenderness in his inguinal region. Radiographs were normal. An magnetic resonance imaging revealed a complete avulsion of the rectus femoris from its origin on the anterior inferior iliac spine. Following discussions of his treatment options, the patient chose to undergo operative management of the injury. A surgical repair was performed of the tendon of the direct head to the anterior inferior iliac spine through bone tunnels. He had a full recovery over the next 6 months and subsequently returned to unrestricted active military duty.

Abstract
We conducted a prospective, randomized study to determine if patients with midshaft clavicle fractures would benefit from immediate operative stabilization with a modified Hagie pin in comparison with a matched group treated with nonoperative therapy. At a level II trauma center, patients with closed midshaft clavicle fractures were prospectively randomized to receive either operative or nonoperative treatment. Fifty-seven (29 operative, 28 nonoperative) patients were enrolled in the study. Operative patients underwent open reduction and internal fixation of the clavicle using a modified Hagie pin; nonoperative patients were treated with a sling for comfort. All patients were followed at regular intervals for 1 year. They were evaluated for radiographic healing and complications and were scored with the Single Assessment Numeric Evaluation and L'Insalata instruments. Injury severities and radiographs were not statistically significantly different between the 2 groups. Functional scores in the operative group were slightly higher at 3 weeks, and the nonoperative group had slightly higher scores at 6 months and 1 year. The only statistically significant difference between the groups was at 3 weeks. Percentage follow-up at 1 year was 93% for the operative group and 82% for the nonoperative group. One patient in each group developed a nonunion, and 1 patient in each group had a refracture. Complications were higher in the operative group, and most were related to pin prominence at the posterior shoulder. Results of this study suggest that, though patients with midshaft clavicle fractures had higher functional scores at short-term follow-up after internal fixation, functional scores were similar at 6 months and 1 year. In addition, internal fixation with a modified Hagie pin was associated with a higher complication rate.

Abstract
Little is known about the in vivo behavior of bioabsorbable suture anchors. A goat model was used to biomechanically and histologically test bioabsorbable and metallic suture anchors in an intra-articular environment at 0, 6, and 12 weeks. Significantly greater force was required to break the bioabsorbable construct than the metallic construct at 0 and 6 weeks. Failure of the metallic anchor constructs occurred at the eyelet. Histological analysis of both bone-anchor interfaces demonstrated equally good osteointegration without evidence of osteolysis. The bioabsorbable suture anchor tested is safe for use in clinical practice without concerns for the strength of the construct or bony reaction to the material.

Abstract
BACKGROUND There is a common belief that surgical reconstruction of an acutely torn anterior cruciate ligament (ACL) should be delayed for at least 3 weeks because of the increased incidence of postoperative motion loss (arthrofibrosis) and suboptimal clinical results. HYPOTHESIS There is no difference in postoperative range of motion or stability after ACL reconstructions performed either acutely or delayed. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS Patients with an acute ACL tear were prospectively randomized to either early (within 21 days) or delayed (beyond 6 weeks) reconstruction using autograft hamstring tendon. Previous knee surgery on the index extremity and a multiligamentous injury were exclusionary criteria. Surgical technique and postoperative rehabilitation were identical for all patients. Postoperative assessments included range of motion and KT-1000 arthrometer measurements compared with the contralateral knee. Standardized outcome measures were used including single assessment numeric evaluation (SANE), Lysholm, and Tegner Activity Score. RESULTS Seventy consecutive patients were enrolled, and 1 patient was dropped after a postoperative infection. Sixty-nine patients (34 acute, 35 delayed) with an average age of 27 years composed the study cohort. The mean time from injury to surgery was 9 days (range, 2-17 days) for patients in the early group and 85 days (range, 42-192) for those in the delayed group. The average follow-up from surgery was 366 days (range, 185-869). Articular cartilage and meniscal injuries were comparable between the 2 groups. There were no significant differences between the 2 treatment groups in degrees of extension or flexion lost relative to the nonoperative side, operative time, KT-1000 arthrometer differences, or subjective knee evaluations. CONCLUSION Excellent clinical results can be achieved after ACL reconstructions performed soon after injury using autograft hamstrings. Although the authors do not advocate that all reconstructions should be performed acutely, they found that early ACL reconstructions do not result in loss of motion or suboptimal clinical results as long as a rehabilitation protocol emphasizing extension and early range of motion is employed.

Abstract
BACKGROUND Arthroscopic stabilization for anterior shoulder instability has been reported to result in a higher rate of recurrent instability compared to traditional open techniques. PURPOSE To test the null hypothesis that there is no difference in the clinical outcomes in patients with recurrent anterior shoulder instability treated with open or arthroscopic stabilization. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Magnetic resonance arthrogram studies were obtained preoperatively. These findings were compared to arthroscopic findings. Postoperative evaluations included range of motion, stability, and subjective assessments including Single Assessment Numeric Evaluation, Simple Shoulder Test, Western Ontario Instability Index, and University of California, Los Angeles evaluation. Failure was defined as a second dislocation, recurrent subluxation, or symptoms precluding return to previous work or unrestricted active military duty. RESULTS Sixty-one patients, 29 who received open stabilization and 32 who received arthroscopic stabilization, were evaluated at a mean of 32 months postoperatively (range, 24-48 months). Patient demographics were equivalent. Preoperative magnetic resonance arthrogram findings were confirmed at arthroscopic examination. The mean operative time was significantly shorter for the arthroscopic repairs (59 vs 149 minutes; P < .001). There were 3 clinical failures (2 open stabilizations, 1 arthroscopic stabilization) by the established criteria. There was a statistically significant improvement from preoperative to postoperative Single Assessment Numeric Evaluation scores in both groups (P < .001). The mean loss of motion (compared to the contralateral shoulder) was greater in the open shoulders. Subjective evaluations were equal in both groups. CONCLUSION Clinical outcomes after arthroscopic and open stabilization were comparable. Preoperative magnetic resonance arthrograms in shoulders with anterior instability allow an accurate diagnosis of intra-articular abnormality that correlates well with operative findings. Arthroscopic stabilization for recurrent anterior shoulder instability can be performed safely; the clinical outcomes are comparable to those after traditional open stabilization.

Abstract
Prophylactic ankle taping has been considered the mainstay of ankle injury prevention and has been used at all levels of competitive football. An alternative to taping is a semirigid ankle orthosis. This study prospectively compared the incidence of ankle sprains in high school football players during a single season, after randomization to either prophylactic bracing or taping of both ankles. Of 83 athletes followed up for an entire season, 6 ankle sprains occurred, 3 in each treatment group; and there was no statistically significant difference in the incidence of ankle sprains between the 2 groups. The time required to tape an athlete averaged 67 seconds per ankle, resulting in a total of 97 minutes per ankle during an entire season, and the average cost to tape each ankle during an entire season was greater than the cost of the commercially available brace. The projected cost savings for an athletic program using prophylactic bracing could be substantial when compared with the use of prophylactic taping of the ankle.

Abstract
It has been postulated that lower extremity fasciotomy may disrupt the calf musculovenous pump and predisposes to development of chronic venous insufficiency (CVI). However, studies based on trauma patients who undergo emergent fasciotomy are confounded by the possibility of concomitant vascular and soft tissue injury and use historical controls. This is a prospective study that evaluates venous hemodynamics in young patients undergoing elective fasciotomy for chronic exertional compartment syndrome (CECS), eliminating the problems associated with retrospective study of trauma patients. CECS was diagnosed by history and, when indicated, measurement of compartment pressures. Prior to elective two- or four-compartment fasciotomy, each patient underwent lower extremity air plethysmography (APG) and colorflow duplex ultrasonography. These studies were repeated a minimum of 6 weeks postoperatively. Fifteen patients who had fasciotomies for CECS were studied; two of these patients had bilateral fasciotomies for a total of 17 limbs. There were 13 male and two female patients (average age 31.2 years). APG and colorflow duplex were performed an average of 12 weeks after fasciotomy. Outflow fraction, venous volume, and ejection volume showed no significant changes postoperatively. However, the venous filling index (VFI) increased (0.9 +/- 0.1 vs. 1.1 +/- 0.1 mL/sec; p < 0.05, paired t-test), the ejection fraction tended to decrease (59 +/- 4% vs. 52 +/- 2%; p < 0.08, paired t-test), and the residual volume fraction (RVF) increased (26 +/- 3% vs. 36 +/- 5%; p < 0.05, paired t-test). There were no patients with evidence of deep venous reflux. Two extremities with preoperative greater saphenous vein (GSV) reflux did not worsen, and three extremities developed new GSV reflux following fasciotomy, although VFI remained normal in each extremity. Elective fasciotomy for CECS does not lead to significant venous reflux but likely does diminish calf muscle pump function and increases RVF moderately in young adult patients. With longer follow-up this diminished calf muscle pump function may increase the risk of CVI.

Abstract
BACKGROUND Symptomatic, traumatic posterior shoulder instability is often the result of a posteriorly directed blow to an adducted, internally rotated, and forward-flexed upper extremity. Operative repair has been shown to provide favorable results. Current arthroscopic techniques with suture anchors and the ability to plicate the capsule using a nonabsorbable suture may provide favorable outcomes with reduced morbidity. PURPOSE To evaluate the results of operative shoulder stabilization in patients with traumatic posterior shoulder instability. STUDY DESIGN Case series; Level of evidence, 4. METHODS A consecutive series of patients who underwent arthroscopic or open posterior stabilization for traumatic posterior shoulder instability were evaluated using subjective assessments, physical examinations, the Single Assessment Numeric Evaluation, Rowe score, Simple Shoulder Test, and the Western Ontario Shoulder Instability Index. RESULTS Between May 1996 and February 2002, 31 shoulders (30 patients) underwent posterior stabilization (19 arthroscopically, 12 open). There were 29 men and 1 woman (mean age, 23 years). Preoperatively, all patients had a distinct traumatic cause for the instability. On physical examination, all patients had posterior apprehension and increased (2+, 3+) posterior load-shift testing. Preoperative radiographs and/or magnetic resonance imaging revealed posterior rim calcification or reverse Bankart lesions in 29 cases (94%). At arthroscopy, posterior labral injuries, reverse Bankart lesions, or humeral head defects were identified. Follow-up averaged 40 months, and the mean duration between injury and surgery was 21 months. The mean Single Assessment Numeric Evaluation, Rowe score, Simple Shoulder Test, and Western Ontario Shoulder Instability Index scores, respectively, for the entire group were 89, 87, 11, and 346; for the open group, they were 81, 80, 10.5, and 594; for the arthroscopic group, they were 92, 92, 11.4, and 190. The Western Ontario Shoulder Instability Index (P < .03) and Rowe score (P < .04) outcomes scores for the arthroscopic group were statistically better than those of the open group. Twenty-nine of 31 shoulders were rated as excellent or good. CONCLUSION In the case of traumatic posterior shoulder subluxation, posterior lesions of the labrum ("reverse Bankart"), articular edge, and capsule are observed. Surgical treatment addressing these lesions led to satisfactory results for both the open and arthroscopic treated groups. In this study, an arthroscopic technique utilizing suture anchor repair with capsular placation provided the most favorable outcomes.

Abstract
BACKGROUND Nonoperative treatment of traumatic shoulder dislocations leads to a high rate of recurrent dislocations. HYPOTHESIS Early arthroscopic treatment for shoulder dislocation will result in a lower recurrence rate than nonoperative treatment. STUDY DESIGN Prospective, randomized clinical trial. METHODS Two groups of patients were studied to compare nonoperative treatment with arthroscopic Bankart repair for acute, traumatic shoulder dislocations in young athletes. Fourteen nonoperatively treated patients underwent 4 weeks of immobilization followed by a supervised rehabilitation program. Ten operatively treated patients underwent arthroscopic Bankart repair with a bioabsorbable tack followed by the same rehabilitation protocol as the nonoperatively treated patients. The average follow-up was 36 months. RESULTS Three patients were lost to follow-up. Twelve nonoperatively treated patients remained for follow-up. Nine of these (75%) developed recurrent instability. Six of the nine have required subsequent open Bankart repair for recurrent instability. Of the nine operatively treated patients available for follow-up, only one (11.1%) developed recurrent instability. CONCLUSIONS Arthroscopic stabilization of traumatic, first-time anterior shoulder dislocations is an effective and safe treatment that significantly reduces the recurrence rate of shoulder dislocations in young athletes when compared with conventional, nonoperative treatment.

Abstract
BACKGROUND Pin tract infection is a common complication of external fixation. An antiinfective external fixator pin might help to reduce the incidence of pin tract infection and improve pin fixation. METHODS Stainless steel and titanium external fixator pins, with and without a lipid stabilized hydroxyapatite/chlorhexidine coating, were evaluated in a goat model. Two pins contaminated with an identifiable Staphylococcus aureus strain were inserted into each tibia of 12 goats. The pin sites were examined daily. On day 14, the animals were killed, and the pin tips cultured. Insertion and extraction torques were measured. RESULTS Infection developed in 100% of uncoated pins, whereas coated pins demonstrated 4.2% infected, 12.5% colonized, and the remainder, 83.3%, had no growth (p < 0.01). Pin coating decreased the percent loss of fixation torque over uncoated pins (p = 0.04). CONCLUSION These results demonstrate that the lipid stabilized hydroxyapatite/chlorhexidine coating was successful in decreasing infection and improving fixation of external fixator pins.

Abstract
SUMMARY Seven months after a quadrupled semitendinosus anterior cruciate ligament reconstruction, a 44-year-old active-duty soldier reported symptoms consistent with a medial meniscus tear. Preoperative magnetic resonance imaging showed an intra-articular bioabsorbable interference screw within his intercondylar notch. The screw was retrieved arthroscopically. The graft was intact and functional except for a small portion of the anterior fibers, which were debrided. The patient returned to full activities without complaints.

Abstract
The correct placement of the femoral tunnel is of critical importance in successfully reconstructing a knee with a deficient anterior cruciate ligament. By inserting the femoral guide pin through the anteromedial portal with the knee fully flexed, and subsequently withdrawing the pin from the anterior thigh until just the end of the pin remains at the insertion site at the posterior aspect of the intercondylar notch, the knee can then be safely extended and a thorough arthroscopic evaluation performed. In addition, the arthroscope can now be introduced into the medial portal to better evaluate the pin placement. Thus, visualization of the pin position and accurate placement based upon the intended tunnel size can be confirmed prior to drilling of the femoral tunnel, and more reproducibility in anterior cruciate ligament reconstructions can be achieved.
