Background: There is a paucity of type 2 superior labrum anterior and posterior (SLAP) surgical outcomes with prospective data. Purpose: To prospectively analyze the clinical arthroscopic treatment SLAP tears in young, active patient population, to determine factors associated success failure. Study Design: Case-control study; Level evidence, 3. Methods: Over 4-year period, 225 patients tear were enrolled. Two sports/shoulder-fellowship-trained orthopaedic surgeons performed repairs suture...
Background Clinical examination remains empirical and may be confusing in the setting of rotatory knee instabilities. Computerized navigation systems provide ability to visualize quantify coupled motions during stability examination. Hypothesis An image-free system can reliably register collect multiplanar kinematics Study Design Controlled laboratory study. Methods Coupled were determined by a robotic/UFS testing an 6 cadaveric knees that subjected (1) isolated varus stress (2) combined...
Although increased capsular volume has been implicated in shoulder instability, there is a paucity of clinical evidence to quantify the size capsule with specific instability conditions shoulder.Shoulder area, as measured by magnetic resonance arthrography, patterns instability.Cross-sectional study; Level evidence, 4.During an 8-month period, all patients diagnosis anterior (n = 19), posterior 14), or multidirectional 13) and who were assessed arthrogram reviewed. A group 10 control without...
Prehabilitation prior to anterior cruciate ligament reconstruction should include quadriceps strengthening—improving range of motion and balance proprioception as a minimum. Although the content duration prehabilitation varies in literature, when faced with delay between diagnosis surgery, 4-6 weeks can improve early mid-term strength timing odds patient returning sport.
The optimal treatment of Hill-Sachs injuries is difficult to determine and potentiated by the finding that a injury becomes more important in setting glenoid bone loss, making engagement humeral head on inherently easier. "glenoid track" concept was developed biomechanically quantify effects combined bony defects instability.To clinically evaluate utilizing track measurements both loss.Retrospective cohort.A total 205 patients with recurrent anterior shoulder instability were evaluated,...
Background: The accuracy of diagnostic imaging modalities that are currently used to evaluate dynamic scapholunate ligamentous instability is equivocal. Ultrasound commonly for a wide variety purposes in orthopaedics. purpose the present study was determine efficacy ultrasound diagnosis instability. Methods: Two groups individuals were prospectively studied. Group A included patients with clinical unilateral instability, and B asymptomatic volunteer control subjects. Dynamic examinations...
To determine the outcomes scores of military patients who initially present with a variety shoulder conditions, identify which demonstrate highest correlation per diagnosis, and if difference exists for went onto surgery.Two-hundred seventy five consecutive mean age 36.5 +/- 12.9 at presentation completed baseline assessments that included Single Assessment Numeric Evaluation (SANE), American Shoulder Elbow Surgeons (ASES) Score, Western Ontario Instability Index (WOSI), Rotator Cuff (WORC),...
Background: Glenoid bone loss is a factor that has been inversely associated with the success of shoulder instability repair. Recently, patients an anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesion have also identified as having higher failure rate after surgical Purpose: To determine differences in amount glenoid and to compare demographic factors without ALPSA tears. Study Design: Case-control study; Level evidence, 3. Methods: Over 3-year period, all (N = 83) who were...
Magnetic resonance imaging (MRI) showing an "intact" anterior cruciate ligament (ACL) graft may not correlate well with examination findings. Reasons for ACL dysfunction be from malpositioned tunnels, deficiency of secondary stabilizers, repeat injuries, or a combination factors.To evaluate the concordance/discordance assessment between arthroscopic evaluation, physical examination, and MRI secondarily to contributing variables discordance.Case series; Level evidence, 4.A total 50 revisions...
Objectives: SLAP tears and tendonitis disorders of the long head biceps tendon (LHBT) remain a challenge to treat in an active population. The purpose this study is prospectively compare surgical outcomes primary tenodesis for tenosynovitis young Methods: Over 6-year period, 125 patients with mean age 42.6 (range, 26.3 56.5) diagnosis LHBT were evaluated. Inclusion criteria included clinical type II or anterior shoulder pain who failed conservative management underwent diagnostic...
Complications from shoulder corticosteroid injections are uncommon. This article presents a case of altered color perception and visual disturbances in 29-year-old male active duty Navy SEAL following an intra-articular glenohumeral injection, previously unreported the orthopedic literature. The injection was administered for treatment right-shoulder stiffness occurring approximately 3 months arthroscopic superior labrum anterior-posterior (SLAP) repair subacromial decompression ipsilateral...
Congenital absence of the long head biceps (LHB) tendon is a rare condition. The literature describes unilateral cases, associations with other congenital developmental anomalies, and shoulder instability SLAP tears. We present case bilateral absent LHB tendons subacromial impingement pathology in patient without history trauma or abnormalities.
Surgeon visual estimation of shoulder range motion (ROM) is commonplace in the outpatient office setting and routinely reported clinical research, but reliability accuracy this practice remain unclear. The purpose study to establish remote ROM healthy volunteers symptomatic patients among a large group surgeons. Our hypothesis that would be reliable accurate compared with digital goniometer method.
