Biomechanical Evaluation of Posterior Cruciate Ligament Reconstruction With Quadriceps Versus Achilles Tendon Bone Block Allograft.

Background: Long-term studies of posterior cruciate ligament (PCL) reconstruction suggest that normal stability is not restored in the majority of patients. The Achilles tendon allograft is frequently utilized, although recently, the quadriceps tendon has been introduced as an alternative option due to its size and high patellar bone density.

Purpose/hypothesis: The purpose of this study was to compare the biomechanical strength of PCL reconstructions using a quadriceps versus an Achilles allograft.

Fifty Most Cited Articles for Femoroacetabular Impingement and Hip Arthroscopy.

Growing awareness of femoroacetabular impingement (FAI) and recent innovations in management have resulted in hip arthroscopy becoming one of the fastest-growing orthopedic subspecialties. The purpose of this study was to identify the 50 most cited articles related to the topic of FAI and hip arthroscopy and to analyze their characteristics. The overall number of citations within these articles ranged from 99 to 820.

Application of the Goutallier/Fuchs Rotator Cuff Classification to the Evaluation of Hip Abductor Tendon Tears and the Clinical Correlation With Outcome After Repair.

Purpose: To assess the reliability and reproducibility of the Goutallier/Fuchs classification for the evaluation of abductor tendon tears of the hip, as well as to identify the relation between preoperative tear size, abductor muscle quality, and the success of endoscopic tendon repair.

Methods: This is a retrospective review of 30 consecutive endoscopic abductor tendon repairs performed by a single surgeon over a 2-year period. Preoperative magnetic resonance imaging scans were reviewed, and the muscle was assigned a grade according to the Goutallier/Fuchs classification.

Arthroscopic technique for the treatment of pigmented villonodular synovitis of the hip.

Open synovectomy remains the treatment of choice for pigmented villonodular synovitis (PVNS) of the hip but has shown modest results compared with the treatment of other joints. Recent advances in hip arthroscopy permit a thorough evaluation of the joint surfaces, improved access, and decreased postoperative morbidity. We describe an arthroscopic synovectomy technique for PVNS of the hip.

Topographic analysis of the capitellum and distal femoral condyle: finding the best match for treating osteochondral defects of the humeral capitellum.

Purpose: The purpose of this study was to determine the donor zone of most congruent topographic match by comparing 4 donor sites from the femur with 4 potential recipient sites of osteochondritis dissecans at the capitellum.

Methods: Computed tomography was performed on 5 right elbows and 6 right medial and 6 right lateral distal femoral hemicondyles, which included the femoral notch. Three-dimensional computed tomography models were created and exported into point-cloud models.

Closure of patellar tendon defect in anterior cruciate ligament reconstruction with bone-patellar tendon-bone autograft: systematic review of randomized controlled trials.

Purpose: This study aimed to systematically review the highest level of evidence on anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone (BPTB) autografts with patellar tendon defect closure versus no closure after surgery.

Methods: We performed a systematic review of multiple medical databases using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Level I and Level II randomized controlled trials comparing patellar tendon defect closure to no closure during ACL reconstruction with BPTB autografts were included.

Clinical and functional outcomes after anterior cruciate ligament reconstruction using cortical button fixation versus transfemoral suspensory fixation: a systematic review of randomized controlled trials.

Purpose: To compare clinical and functional outcomes after anterior cruciate ligament (ACL) reconstruction using cortical button versus transfemoral suspensory fixation.

Methods: This systematic review was conducted following the Cochrane handbook guidelines and PROSPERO registration. Only Level I and II randomized controlled trials comparing cortical button and transfemoral suspensory fixation in hamstring ACL reconstruction were included.

Evaluating the quality of Internet information for femoroacetabular impingement.

Purpose: The Internet has become a ubiquitous source of medical information for both the patient and the physician. However, the quality of this information is highly variable. We evaluated the quality of Internet information available for femoroacetabular impingement (FAI).

Tips for successful transtibial anterior cruciate ligament reconstruction.

Anterior cruciate ligament (ACL) reconstruction is one of the most common procedures performed in orthopedics. While results from ACL reconstruction have been highly successful in restoring knee stability and allowing patients to return to sports, a debate continues as to which technique is best for restoring native anatomy and biomechanics. Some have proposed that a transtibial (TT) technique is not able to restore an ACL graft to the native femoral footprint and have advocated independent drilling of the femoral tunnel.

All-inside meniscal repair devices and techniques.

Techniques and devices for meniscal repair are evolving, including for all-inside meniscal repair. The first-generation all-inside meniscal repair devices were simplistic in design, but their technical difficulties and risks led to the development of second-generation devices. These devices employed the suture anchor concept for repair and confirmed the safety of use through standard anterior arthroscopic portals.

Incidence of subsequent injury to either knee within 5 years after anterior cruciate ligament reconstruction with patellar tendon autograft.

Background: The risk of subsequent anterior cruciate ligament injury to either knee after surgery based on sex, age, and activity has not been extensively studied.

Hypotheses: Women have a higher incidence of anterior cruciate ligament injury to the contralateral knee after surgery than men but do not have a difference in injuries to the reconstructed knee. Young, competitive athletes have a higher incidence of injury than older patients.

Knee dislocation with lateral side injury: results of an en masse surgical repair technique of the lateral side.

Background: Knee dislocations with lateral side injury are rare and disabling if not treated.

Hypothesis: An en masse surgical technique to repair the lateral side will provide good stability, and the posterior cruciate ligament will heal when left in situ.

Study Design: Case series; Level of evidence, 4.
