Reliability of the Tönnis Classification and Its Correlation With Magnetic Resonance Imaging and Intraoperative Chondral Damage.

Purpose: To evaluate the reliability of the Tönnis classification in the setting of femoroacetabular impingement (FAI) hips without dysplasia.

Methods: Forty-nine patients with FAI underwent preoperative radiography and magnetic resonance imaging (MRI). Radiographs were evaluated in 2 separate settings by 5 observers and graded according to the Tönnis classification.

Arthroscopic Implantation of a Bio-Inductive Collagen Scaffold for Treatment of an Articular-Sided Partial Rotator Cuff Tear.

The treatment of articular-sided partial rotator cuff tears remains a challenge to the treating orthopaedic surgeon. Treatment algorithms have included nonoperative management, debridement alone, and debridement and subacromial decompression, as well as articular-sided rotator cuff repair and completion of the tear on the bursal side followed by a traditional arthroscopic rotator cuff repair. Implantation of a bio-inductive collagen scaffold on the bursal side of the rotator cuff to potentially heal an articular-sided tear represents a novel approach to this difficult clinical entity.

Neuromuscular problems in foot and ankle: evaluation and workup.

It is essential to determine the functional goals of the patient during the workup and treatment planning stages of neuromuscular disorders involving the foot and ankle. Accurate diagnosis, and informed discussion of treatment options, must be in the context of the patient's disease, cognition, comorbidities, functional attributes, and family environment. A thorough history and physical examination aid in appropriate diagnostic workup and optimal orthopedic management of each patient.

Technique: bone-patellar tendon-bone autograft ACL reconstruction in the young, active patient.

Successful treatment of the anterior cruciate ligament tear in the young, active population can be reliably achieved with an arthroscopic bone-patellar tendon-bone (BTB) autograft reconstruction. Although some contraindications exist, the BTB autograft has been proven to provide for a durable, stable, and highly functional knee. Complications associated with the use of BTB can occur, but measures can be taken to minimize these risks.

Special considerations for ACL graft selection in the young, active military patient.

Anterior cruciate ligament (ACL) injury is an extremely common injury in the young, physically demanding active duty military population. The diagnosis of an ACL injury in active duty military personnel often requires special consideration in terms of return to function, reliability, and performance of the knee-often in life-threatening situations when one has to rely on a stable knee for survival. This article outlines the considerations of ACL surgical treatment in the active duty military population, with an emphasis on the young, physically competitive athlete to optimize outcomes.

Arthroscopic revision Bankart repair: a preliminary evaluation.

Arthroscopic stabilization of primary, recurrent anterior shoulder instability has become the procedure of choice with infrequent exceptions. Failures of stabilization can and do occur. This is a Level IV retrospective analysis of arthroscopic revision Bankart surgery performed on 15 non-consecutive patients over a 4-year period with an average 22-month follow-up.

Postarthroscopic glenohumeral chondrolysis of the shoulder.

Postarthroscopic glenohumeral chondrolysis is a devastating, poorly understood, and relatively rare complication. True chondrolysis involves the dissolution of articular cartilage, including the matrix and cellular elements, leading to premature and irreversible articular cartilage loss. Several factors have been implicated in this phenomenon; however, to date, no study has conclusively ascertained the causation.

Rehabilitation of biceps tendon disorders in athletes.

The diagnosis and management of an active patient with biceps disease can be challenging for the treating physician. A careful review of the function, anatomy, and pathology of biceps in conjunction with a thorough, knowledgeable history and physical examination can yield a working diagnosis in this challenging patient population. The physician must also be aware of the physiology of postsurgical repair and advocate appropriate rehabilitation activities that correlate with the timeline of secure tissue healing.

Displacement of the posterior horn of the lateral meniscus into posterolateral compartment: an unusual injury pattern.

We report a case of acute ACL injury with an unusual lateral meniscal tear pattern. The entire posterior horn of the lateral meniscus was avulsed from its attachments while remaining in continuity with the body of the meniscus. It was displaced posteriorly and laterally to the popliteus tendon so that it was not immediately visible at the time of arthroscopy.
