Morphological Assessment of MACI Grafts in Patients with Revision Surgery and Total Joint Arthroplasty.

Objective: To compare the histological and immunohistochemical characteristics of matrix-assisted chondrocyte implantation (MACI) grafts between patients with revision surgery and patients with total joint arthroplasty.

Methods: Biopsies of MACI grafts from patients with revision and total joint arthroplasty. The graft tissue characteristics and subchondral bone were examined by qualitative histology, ICRS (International Cartilage Repair Society) II scoring and semiquantitative immunohistochemistry using antibodies specific to type I and type II collagen.

Current Perspectives of the Australian Knee Society on Rehabilitation and Return to Sport After Anterior Cruciate Ligament Reconstruction.

Context: The importance of rehabilitation and evaluation prior to return to sport (RTS) in patients undergoing anterior cruciate ligament reconstruction has been reported.

Objective: This study sought to investigate current perspectives of Australian orthopedic surgeons on rehabilitation and RTS evaluation.

Design: Survey.

Patellar eversion during total knee replacement: a prospective, randomized trial.

Background: Proponents of minimally invasive total knee arthroplasty argue that retracting rather than everting the patella results in quicker postoperative recovery and improved function. We aimed to investigate this in patients undergoing knee arthroplasty through a standard medial parapatellar approach.

Methods: In a prospective randomized double-blinded study, sixty-eight patients undergoing total knee arthroplasty through a standard medial parapatellar approach were assigned to either retraction or eversion of the patella.

Gluteal tendon repair augmented with a synthetic ligament: surgical technique and a case series.

We describe an augmented surgical repair technique for gluteus minimus and medius tears, along with a supportive case series. A consecutive series of 22 patients presenting with clinical and radiological findings consistent with hip abductor tears, who had undergone failed prior conservative treatments, were prospectively recruited. Patients underwent open bursectomy, Y-iliotibial release, debridement of the diseased tendon, decortication of the trochanteric foot-plate and reattachment augmented with a LARS ligament through a trans-osseous tunnel, together with suture anchors.

Arthroscopic Delivery of Matrix-Induced Autologous Chondrocyte Implant: International Experience and Technique Recommendations.

Objective: To identify consensus recommendations for the arthroscopic delivery of the matrix-induced autologous chondrocyte implant.

Design: An invited panel was assembled on November 20 and 21, 2009 as an international advisory board in Zurich, Switzerland, to discuss and identify best practices for the arthroscopic delivery of matrix-induced autologous chondrocyte implantation.

Results: Arthroscopic matrix-induced autologous chondrocyte implantation is suitable for patients 18 to 55 years of age who have symptomatic, contained chondral lesions of the knee with normal or corrected alignment and stability.

Functional outcome of matrix-associated autologous chondrocyte implantation in the ankle.

Background: The technique of Matrix-associated autologous chondrocyte implantation (MACI) is well established with satisfactory outcomes up to 5 years in the knee. Fewer series describe the outcomes of this technique in the ankle. We present the functional outcomes of the technique for a single surgeon series in a general hospital setting.
