Editorial Commentary: When Treating Cartilage Lesions With Osseous Involvement, Biologic "Chondrofacilitation" Using Either Bone Marrow Aspirate Concentrate or Mesenchymal Stem Cells Augments Microfracture.

The use of biologic augmentation following microfracture for symptomatic cartilage defects of the knee with osseous involvement shows encouraging results. Bone marrow aspirate concentrate provides growth factors to the injury site, such as vascular endothelial growth factor, platelet-derived growth factor, transforming growth factor-βa, and bone morphogenetic proteins in addition to the mesenchymal stem cells present in the concentrate. Cellular-based therapies like mesenchymal stem cells are becoming more widely used in conjunction with surgical treatment of focal cartilage lesions with early promising results.

Long-term Patient-Reported Outcome Measures Following Particulated Juvenile Allograft Cartilage Implantation for Treatment of Difficult Osteochondral Lesions of the Talus.

Background: Conventional methods are not suitable for difficult to treat osteochondral lesions of the talus (OCLTs). The role of particulated juvenile allograft articular cartilage implantation is not well elucidated for long-term patient outcomes.

Methods: Thirteen patients with difficult-to-treat OCLTs underwent arthroscopy-assisted implantation of particulated juvenile articular cartilage graft into defects from 2010 to 2012 by the same surgeon.

Endoscopic Implantation of Bioinductive Patch for Chronic Partial Retearing After Hamstring Repair.

Proximal hamstring tendon avulsions are a relatively rare type of hamstring injury associated with persistent morbidity, including pain, weakness, and functional limitations. Open or endoscopic surgical repair is the standard treatment for complete tendon avulsions or partial tears that remain symptomatic despite conservative management in relatively young, healthy, and active patients. However, complications known to occur include retearing of the hamstring, infection, nerve injury, inability to return to work or sport, subjective persistent weakness, and subjective persistent pain.

Factors Predicting Hemodynamic Interventions During Inpatient Admission After Shoulder Arthroplasty.

Background: We sought to identify the influence of shoulder arthroplasty (SA) type (primary anatomic, primary reverse, revision) and indication (fracture, arthritis) on the risk of postoperative packed red blood cell transfusion (pRBCT) and intravenous fluid bolus (IVFB).

Methods: Patients who underwent SA from 2013 through 2016 at our institution were categorized into four groups: primary anatomic (pTSA; N = 298), primary reverse (pRTSA; N = 292), revision (RevSA; N = 133), and shoulder arthroplasty for fracture (SAF; N = 58). Basic demographics, intraoperative metrics, preoperative lab values, and postoperative interventions (pRBCT and IVFB) were retrieved from electronic records.

Atypical Hip Pain in Femoroacetabular Impingement: A Comparison of Outcomes Based on Primary Hip Pain Location.

Background: Patients with symptomatic femoroacetabular impingement (FAI) typically have anterior groin pain. However, a subset of these patients may have pain located laterally, posteriorly, or in a combination of locations around the hip.

Purpose: To report and compare outcomes of hip arthroscopy for patients with FAI and atypical hip pain versus classic anterior groin pain.

Current data do not support routine use of patient-specific instrumentation in total knee arthroplasty.

The purpose of this systematic review and meta-analysis is to compare patient-specific instrumentation (PSI) versus standard instrumentation for total knee arthroplasty (TKA) with regard to coronal and sagittal alignment, operative time, intraoperative blood loss, and cost. A systematic query in search of relevant studies was performed, and the data published in these studies were extracted and aggregated. In regard to coronal alignment, PSI demonstrated improved accuracy in femorotibial angle (FTA) (P=0.

Arthroscopic anatomic humeral head reconstruction with osteochondral allograft transplantation for large hill-sachs lesions.

Anatomic reconstruction of the humeral head with osteochondral allograft has been reported as a solution for large Hill-Sachs lesions with or without glenoid bone loss. However, to date, varying techniques have been used. This technical note describes an arthroscopic reconstruction technique using fresh-frozen, side- and size-matched osteochondral humeral head allograft.

Impact of diabetes mellitus on surgical outcomes in sports medicine.

Diabetes mellitus (DM) affects a significant proportion of the patients evaluated and treated by orthopedic surgeons who specialize in sports medicine. Sports-medicine-related conditions associated with DM include tendinopathy, adhesive capsulitis of the shoulder, and articular cartilage disease. This article reviews the current literature adressing the effect of DM on surgical outcomes in sports medicine.

10-year follow-up wear analysis of first-generation highly crosslinked polyethylene in primary total hip arthroplasty.

Our goal was to report a 10-year follow up of linear penetration rates for HCLPE, and to determine whether a difference exists between penetrations measured on pelvis or hip anterior-posterior radiographs. We reviewed 48 total hip arthroplasties where a first-generation HCLPE liner was used. Femoral head penetration was measured on both AP pelvis and hip radiographs.
