BACKGROUND As the number of anterior cruciate ligament (ACL) injuries and primary ACL reconstruction surgeries increase, the absolute number of re-ruptures or failures has also subsequently increased. In our study, we look at the causes of failure in the primary surgery and also report the clinical and functional outcomes in our series of patients undergoing revision surgery. MATERIALS AND ME...

The purpose of the present study is to present the results of anterior cruciate ligament (ACL) augmentation for patients having rotational instability despite an intact vertical graft in lieu of conventional revision ACL reconstruction. ACL augmentation surgery with a horizontal graft was performed to augment a healed vertical graft on five patients and an accelerated rehabilitation protocol wa...

Autogenous cartilage has generally been considered the gold standard grafting material in reconstructive septorhinoplasty for volume filling and structural support. In the restructuring of the nasal skeleton, autogenous cartilage can be harvested from the nasal septum, the auricle or the rib, but costal cartilage is considered the best graft material in patients requiring major reconstruction. ...

The objective of this study was to investigate the potential application of cell-seeded biomaterials for revision arthroplasty and the reconstruction of major joints using the impaction grafting technique. Using morselized cancellous bone graft as a porous scaffold, MG63 cells were seeded on the scaffold and impacted into an acetabulum cup model using a mechanical device constructed from data o...

BACKGROUND A large, multicenter, 10-year observational study is being conducted to compare the long-term safety and effectiveness of Natrelle silicone breast implants with saline implants or national norms. Study baseline data and surgical characteristics are reported here. METHODS Women seeking primary augmentation, revision-augmentation, primary reconstruction, or revision-reconstruction pa...

BACKGROUND There are limited data reporting outcomes after revision arthroscopic surgery for residual femoroacetabular impingement (FAI). HYPOTHESIS (1) Revision arthroscopic FAI correction results in improved outcomes, but they are inferior to those of primary arthroscopic FAI correction. (2) Improved postrevision radiographic parameters are predictive of better outcomes. STUDY DESIGN Coho...

Giant cell tumor of the bones occurring in the first metacarpals frequently requires entire metacarpal resection due to the aggressive nature and high rate of recurrence. Bone reconstruction can be performed with autogenous bone grafts. Here we describe a new technique of reconstruction using a patient-matched three-dimensional printed titanium first metacarpal prosthesis. This prosthesis has a...

A 57-year-old man presented with persistent hyperparathyroidism following primary parathyroidectomy. A four-dimensional computed tomography scan with three-dimensional reconstruction showed two parathyroid glands (one right and one left) and anatomic variation from previous surgery. Revision surgery was performed revealing the parathyroid glands as expected from the preoperative three-dimension...
