Although patellofemoral instability is among the most prevalent knee disorders, management of patients with this condition complex and remains variable, given lack long-term, high-level clinical outcome studies to compare various operative nonoperative modalities.To discover a consensus within treatment controversies in experienced surgeons specific interest joint.Expert opinion; Level evidence, 5.A 3-step modified Delphi technique was used establish consensus. A 34-question, case-based...
Background: Medial patellofemoral ligament (MPFL) reconstruction has become one of the most common and widely used procedures to regain stability among patients with recurrent lateral patellar dislocation. While recent studies demonstrated low recurrence rates, improved patient-reported outcome measures, a high rate return sports, limited literature explored its effectiveness as an isolated intervention in context trochlear dysplasia. Purpose: To determine efficacy MPFL treating instability...
The role of arthroscopic repair in the treatment posterior shoulder instability remains poorly defined.To evaluate results Bankart lesions.Retrospective review.Records were reviewed 27 shoulders (26 patients). All patients male with a mean age 28.7 years; all cases symptoms preceded by traumatic event. Fourteen had 2+ to 3+ translation noted under preoperative anesthesia. capsulolabral complex was found be detached from glenoid rim cases; bioabsorbable tack fixation used for repair.At...
Background: Tibial tubercle osteotomy (TTO) is a well-established surgical treatment option for patellofemoral instability and pain. TTO with distalization (TTO-D) indicated patients instability, patellar malalignment, patella alta. The current literature demonstrates several complications that may be associated TTO, reportedly higher rates of TTO-D. Purpose: To analyze compare complication after without (TTO-ND) TTO-D assess risk factors complications. Study Design: Cohort study; Level...
Background Full-thickness cartilage lesions of the patella represent a common source pain and dysfunction. Previously reported surgical treatment options include marrow stimulation, cell-based treatments, osteochondral transfer. Minced juvenile allograft is novel option that allows for single stage approach these lesions. Hypothesis Particulated (PJAC) chondral defects would offer acceptable lesion fill rates, mature over time, not be associated with any negative biologic effects on...
Cartilage lesions of the patellofemoral joint constitute a frequent abnormality. Patellofemoral conditions are challenging to treat because complex biomechanics and morphology.To develop consensus statement on functional anatomy, indications, donor graft considerations, surgical treatment, rehabilitation for management large chondral osteochondral defects in using modified Delphi technique.Consensus statement.A working group 4 persons generated list statements related form basis an initial...
The purpose of this study is to determine the efficacy amniotic suspension allograft (ASA) compared hyaluronic acid (HA) and saline at up 12 months follow-up through use patient-reported outcomes, immunoglobulin levels, anti-human leukocyte antigen (HLA) levels.Within multicenter study, 200 patients were randomized 1:1:1 a single intra-articular injection saline, HA, or ASA. Patient-reported including Knee Injury Osteoarthritis Outcome Score (KOOS) visual analog scale (VAS) score, collected...
Understanding specific risk profiles for each patient and their propensity to experience clinically meaningful improvement after anterior cruciate ligament reconstruction (ACLR) is important preoperative counseling management of expectations.To develop machine learning algorithms predict achievement the minimal difference (MCID) on International Knee Documentation Committee (IKDC) score at a minimum 2-year follow-up ACLR.Case-control study; Level evidence, 3.An ACLR registry patients from 27...
Background: While tibial tubercle osteotomy (TTO) is a highly effective treatment for patellofemoral malalignment, some patients may have recurrent symptoms after surgery. To date, there are little data on revision TTO (rTTO) and its outcomes. Purpose: evaluate the (1) reasons (2) complications following rTTO. Study Design: Case series; Level of evidence, 4. Methods: This was retrospective review who underwent rTTO from single high-volume surgeon between 2016 2023. All included had minimum 3...
Background: Management approaches and surgical techniques for patellofemoral instability (PFI) continue to lack clear clinical guidelines indications. Medial ligament reconstruction (MPFLR) is the most frequently used procedure; however, variation in technique remains significant, particularly skeletally immature patients. Purpose/Hypothesis: The purpose of this study was examine variations MPFLR patients as represented by 20 orthopaedic surgeons with different experience levels specialty...
Background: Radiological risk factors for an osteochondral fracture (OCF) associated with patellar instability are rarely studied, particularly in patients recurrent instability. Purpose: To identify specific radiological characteristics that relate to the increased prevalence of OCFs Study Design: Case-control study; Level evidence, 3. Methods: Patient data (n = 730) from Justifying Patellar Instability Treatment by Early Results (JUPITER) multicenter study were reviewed findings. Trochlear...
Abstract Background The aim of the study was to provide a gender-based analysis results large, multi-centre randomized controlled trial (RCT) comparing novel cell-free aragonite-based scaffold with standard care (i.e. debridement/microfractures) for treatment chondral/osteochondral defects in knees or without concurrent osteoarthritis. Materials and methods A total 251 patients were included: 167 group 84 control. In group, there 105 males 59 females, whereas control consisted 51 32 females....
Background: There is growing interest in sagittal plane malalignment as a risk factor for patellofemoral chondral wear and, correspondingly, an important measure to correct when performing certain tibial tubercle osteotomy (TTO) procedures. However, radiographic method anteriorization after TTO has not been described. Purpose: To develop and validate of measuring TTO. Study Design: Cross-sectional study (diagnosis); Level evidence, 3. Methods: Patients treated by 2 high-volume sports...
Background: Addressing patella alta often involves a distalization of the tibial tubercle with an osteotomy. Yet such osteotomies have several potential complications, including nonunion, fracture, and hardware irritation. In addition, are contraindicated in children because presence open apophysis. Purpose/Hypothesis: The primary aim this study was to quantify change Caton-Deschamps Index (CDI) maximum patellar tendon elongation achieved cyclic loading novel transection-free imbrication...
Patella alta describes an abnormally high-riding patella in relationship to the femur and has been shown correlate with patellofemoral pain, instability, chondromalacia, arthrosis. Conventional measurements of involve multiple are often not defined on cross-sectional imaging as related radiographs.Patellar articular overlap sagittal magnetic resonance (MRI) will well conventional measured by a standardized technique our group.Cohort study (diagnosis); Level evidence, 2.MRIs 239 knees were...
