Background: Most surgeons believe that graft choice for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome; however, revision may be limited due previously used grafts. Hypotheses: Autograft use would result in increased sports function, activity level, and decreased osteoarthritis symptoms (as measured by validated patient-reported outcome instruments). failure reoperation rate 2 years after ACL reconstruction. Study Design: Cohort study; Level of...
Background: At the time of anterior cruciate ligament (ACL) reconstruction, there are usually concurrent meniscal and articular cartilage injuries. It is unclear if a significant difference between intra-articular injuries at primary ACL reconstruction compared with revision reconstruction. Purpose: To compare found surgery to determine associations specific findings. Study Design: Cohort study (prevalence); Level evidence, 2. Methods: Primary surgeries were identified from Multicenter...
The factors that lead to patients failing multiple anterior cruciate ligament (ACL) reconstructions are not well understood.Multiple-revision ACL reconstruction will have different characteristics than first-time revision in terms of previous and current graft selection, mode failure, chondral/meniscal injuries, surgical charactieristics.Case-control study; Level evidence, 3.A prospective multicenter database was utilized for the time period from March 2006 June 2011. Patients were divided...
Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have worse outcomes compared with primary ACL reconstructions. Purpose/Hypothesis: The purpose of this study was determine if the prevalence, location, and/or degree meniscal and chondral damage noted at time revision predicts activity level, sports function, osteoarthritis symptoms 2-year follow-up. hypothesis that loss high-grade will result in lower levels, decreased participation, more pain,...
Background: While revision anterior cruciate ligament reconstruction (ACLR) can be performed to restore knee stability and improve patient activity levels, outcomes after this surgery are reported inferior those primary ACLR. Further reoperations ACLR have an even more profound effect on satisfaction outcomes. However, there is a current lack of information regarding the rate risk factors for subsequent Purpose: To report reoperations, procedures performed, reoperation 2 years Study Design:...
Background: Although graft choice may be limited in the revision setting based on previously used grafts, most surgeons believe that for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome. Hypothesis: In ACL setting, there would no difference between autograft and allograft rerupture rate patient-reported outcomes (PROs) at 6-year follow-up. Study Design: Cohort study; Level of evidence, 2. Methods: Patients who had surgery were identified prospectively...
Background: Knees undergoing revision anterior cruciate ligament (ACL) reconstruction typically have more intra-articular injuries than do knees primary reconstruction. Hypothesis: Previous partial meniscectomy (PM) is associated with a higher rate of chondral lesions at ACL reconstruction, whereas previous meniscal repair (MR) not compared no surgery. Study design: Cohort study (Prevalence); Level evidence, 2. Methods: Data from multicenter cohort was reviewed to determine the history prior...
Background: The occurrence of physiologic knee hyperextension (HE) in the revision anterior cruciate ligament reconstruction (ACLR) population and its effect on outcomes have yet to be reported. Hypothesis/Purpose: prevalence HE ACLR 2-year outcome were studied with hypothesis that preoperative ≥5° is a risk factor for (ACL) graft rupture. Study Design: Cohort study; Level evidence, 2. Methods: Patients undergoing identified prospectively enrolled between 2006 2011. inclusion criteria...
Background: Anterior cruciate ligament (ACL) reconstruction failure occurs in up to 10% of cases. Technical errors are considered the most common cause graft despite absence validated studies. Limited data available regarding agreement among orthopaedic surgeons causes primary ACL and accuracy tunnel placement. Hypothesis: Experienced knee have a high level interobserver reliability about failure, anatomic characteristics, Study Design: Cohort study (diagnosis); Level evidence, 3. Methods:...
Knees undergoing revision anterior cruciate ligament reconstruction (rACLR) have a high prevalence of articular cartilage lesions.The chondrosis at the time rACLR is associated with meniscal status and lower extremity alignment.Cross-sectional study; Level evidence, 3.Data from prospective Multicenter ACL Revision Study (MARS) cohort were reviewed to identify patients preoperative alignment films. Lower was defined by weightbearing line (WBL) as percentage tibial plateau width, while...
Background: Patient-reported outcomes (PROs) are a valid measure of results after revision anterior cruciate ligament (ACL) reconstruction. Revision ACL reconstruction has been documented to have worse when compared with primary Understanding positive and negative predictors PROs will allow surgeons modify potentially improve outcome for patients. Purpose/Hypothesis: The purpose was describe test the hypothesis that patient- technique-specific variables associated these outcomes. Study...
Tenodesis is an accepted treatment option in the management of pathology involving long head biceps (LHB). Among common causes for revision surgery after tenodesis are residual pain within bicipital groove, cramping, early fatigue, and deformity. Most technical descriptions arthroscopic involve fixation LHB tendon or proximal to intertubercular sulcus thus fail address described sources this anatomic location. Suprapectoral offers surgeon ability remove from groove by fixating more distally....
Articular cartilage health is an important issue following anterior cruciate ligament (ACL) injury and primary ACL reconstruction. Factors present at the time of reconstruction may influence subsequent progression articular damage.Larger meniscus resection reconstruction, increased patient age, body mass index (BMI) are associated with odds worsened damage revision reconstruction.Case-control study; Level evidence, 3.Subjects who had data in databases Multicenter Orthopaedics Outcomes...
Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have worse outcomes compared with primary ACL reconstruction. Hypothesis: Certain factors under the control of surgeon at time revision surgery can both negatively and positively affect outcomes. Study Design: Case-control study; Level evidence, 3. Methods: Patients undergoing were identified prospectively enrolled between 2006 2011. Data collected included baseline demographics, intraoperative...
Many clinicians believe that after fracture of the hook hamate, nonunions are rule rather than exception.To describe a previously unreported condition in which fractured hamate unites only along its ulnar column and causes pain similar to cases nonunion.Retrospective review.Eight patients who had sustained were identified, on basis their persistent pain, as having achieved partial union. This diagnosis was made despite evidence computed tomography healed bone across significant portion...
Background: Meniscal preservation has been demonstrated to contribute long-term knee health. This a successful intervention in patients with isolated tears and associated anterior cruciate ligament (ACL) reconstruction. However, the results of meniscal repair setting revision ACL reconstruction have not documented. Purpose: To examine prevalence 2-year operative success rate repairs setting. Study Design: Case-control study; Level evidence, 3. Methods: All cases concomitant from multicenter...
Background: Meniscal and chondral damage is common in the patient undergoing revision anterior cruciate ligament (ACL) reconstruction. Purpose: To determine if meniscal and/or articular cartilage pathology at time of ACL surgery significantly influences a patient’s outcome 6-year follow-up.

Abstract Infection is a rare occurrence after revision anterior cruciate ligament reconstruction (rACLR). Because of the low rates infection, it has been difficult to identify risk factors for infection in this patient population. The purpose study was report rate following rACLR and assess whether associated with patient‐ surgeon‐dependent factors. We reviewed two large prospective cohorts patients postoperative infections rACLR. Age, sex, body mass index (BMI), smoking status, history...
Background: Anterior cruciate ligament (ACL) revision cohorts continually report lower outcome scores on validated knee questionnaires than primary ACL at similar time points after surgery. It is unclear how these outcomes are associated with physical activity physician clearance for return to recreational or competitive sports Hypotheses: Participants who either multiple a singular sport surgery will decreased symptoms, increased level, and improved function as measured by patient-reported...
HISTORICAL PERSPECTIVE Medial elbow instability may be the result of one traumatic event or cumulative effect repetitive microtrauma. The anterior bundle ulnar collateral ligament (UCL) is major stabilizing structure resisting valgus force at (1–7). In most cases isolated trauma to rarely leads symptomatic instability. However, overhead throwing athletes place high stress on elbow, which produce symptoms UCL insufficiency, resulting from a tear attenuation ligament. Injury this occurs...
