Subcutaneous pretibial cyst formation associated with anterior cruciate ligament allografts: a report of four cases and literature review.

Four clinical cases are described in which patients who had undergone anterior cruciate ligament reconstruction developed ganglion-like cysts at the external aparature of the tibial channel. All patients underwent operative treatment including curettage and bone grafting with the successful resolution of the cysts. A proposal, based on the incomplete incorporation of allograft tissues within bone tunnels, is given for the pathogenisis of these cysts, accompanied by a detailed description of the relevant literature.

Knee sprains and acute knee hemarthrosis: misdiagnosis of anterior cruciate ligament tears.

A retrospective study and a prospective study comprising 186 patients with "typical knee sprains" were conducted at the University of Cincinnati Sports Medicine Institute. We concluded that the commonly encountered mild knee sprain may actually be a serious knee injury whose severity is easy to underestimate. Traumatic hemarthrosis indicates a serious knee injury. Arthroscopy showed that a surprising 72 percent of the patients in the prospective study had disruption of the anterior cruciate ligament (partial tear in 28%, complete tear in 44%). In addition of the 72 percent of anterior cruciate ligament tears, associated injuries included meniscus tears (62%), osteochondral fractures or fissures to the joint surface (20%), and other significant ligament disruptions (20%). Any joint effusion within 24 hours of knee injury, no matter how trivial, suggests a need for further diagnostic tests beyond the initial examination. In our study, our clinical examination alone consistently underestimated the extent of injury, resulting in inadequate information for treatment descisions. Conversely, arthroscopy and examination under anesthesia provided information on the extent of injury, allowing an accurate diagnosis and formulation of a rational treatment program.

Patellar malalignment: a treatment rationale.

A general review of present-day treatment for patellofermoral malalignment is presented. These regimens are viewed in light of known anatomical, biomechanical, and pathophysiological principles. We stress the need for a sound knowledge of biomechanical and pathophysiological principles prior to the initiation of surgical or rehabilitative techniques. Three major categories of surgery are discussed: 1) simple lateral release, 2) proximal "dynamic" realignment, and 3) distal patellar tendon realignment. A comprehensive rehabilitation program is presented based on sound biomechanical principles and known surgical techniques. We wish to stress the "non-surgical," conservative approach to patellofemoral malalignment through the use of a well-orgainzed and structured rehabilitation program.

Pes cavovarus. Review of a surgical approach using selective soft-tissue procedures.

This study reviews the surgical treatment of twenty-seven patients (thirty-nine feet) with cavovarus foot deformity. The patients' ages ranged from six months to fifteen years. Only those patients who had at least a two-year follow-up were selected for statistical analysis. This group comprised twenty patients (twenty-seven feet). A standardized treatment program was used, based on the flexibility of the deformity. A radical plantar or plantar medial release was employed as indicated, in combination with tendon transfers or osteotomy of the fore part of the foot, or both. All patients were available for follow-up examination and special roentgenograms of the hind part of the foot. Follow-up appraisal of the patients with more than two years' follow-up revealed more than 85 per cent acceptable results with no major complications.
