Internal rotation of the tibial component is frequent in stiff total knee arthroplasty.

Background: Stiffness complicating TKA is a complex and multifactorial problem. We suspected internally rotated components compromised motion because of pain, patellar maltracking, a tight medial flexion gap, and limited femoral rollback on a conforming lateral tibial condyle.

Questions/purposes: We sought to determine: (1) the incidence of internal rotation of the femoral and tibial components in stiff TKAs; (2) if revision surgery that included correction of rotational positioning improved pain, ROM, and patellar tracking; and (3) if revision altered nonrotational radiographic parameters.

Revision anterior cruciate ligament reconstruction.

Revision reconstruction of the anterior cruciate ligament (ACL) introduces several diagnostic and technical challenges in comparison with primary ACL reconstruction. With the increasing numbers of original reconstructions combined with the continued expectation of high-level athletic participation, revision ACL reconstruction is likely to become more frequent. The purpose of this article was to summarize the causes of failure and the evaluation of the patient with recurrent instability.

Femoral radiographic landmarks for lateral collateral ligament reconstruction and repair: a new method of reference.

Background: Little work has been made regarding the use of radiographic landmarks in fibular collateral ligament reconstruction. Radiographic tools can be of use to the surgeon in posterolateral reconstruction as secondary checks in the setting of tissue and bony attrition.

Hypothesis: Using standardized radiographic imaging, a zone for femoral tunnel placement in lateral collateral ligament (LCL) reconstruction can be identified.

2009 survey results: surgeon practice patterns regarding arthroscopic surgery.

A survey was conducted to collect information on the surgical management and practice preferences of the audience members at a recent continuing medical education conference. Participants were polled on a variety of surgical topics, and their responses were recorded using a wireless audience response system. The answers were tabulated and are presented in this report.

Anatomical confirmation of the use of radiographic landmarks in medial patellofemoral ligament reconstruction.

Background: A recent study has described radiographic landmarks for femoral insertion of the medial patellofemoral ligament. Clinical relevance and application of these landmarks for surgical reconstruction have yet to be determined.

Hypothesis: Radiographic landmarks can be used to accurately determine the femoral insertion of the medial patellofemoral ligament in a percutaneous fluoroscopically guided surgical technique.

Achilles lengthening/posterior tibial tenotomy with immediate weightbearing for patients with significant comorbidities.

Background: Fixed equinovarus deformities can be challenging to treat especially in medically debilitated patients. The purpose of this study was to evaluate Achilles lengthening with posterior tibial tenotomy and immediate weightbearing in this difficult group of patients.

Materials And Methods: Thirteen extremities in 10 patients underwent Achilles lengthening and posterior tibial tenotomy for fixed equinovarus deformities with significant medical comorbidities.
