Anterior cruciate ligament reconstruction with autografts.

Arthroscopically assisted ACL reconstruction has undergone rapid development in recent years. Although achievement of stability has been well-documented in open ACL reconstructive procedures, improved results may be obtained by reducing operative morbidity. Arthroscopically assisted ACL reconstruction appears to offer significantly diminished morbidity and thus offers more predictable rehabilitation, at least initially, after surgery. Improvements in instrumentation continue to refine the precision of this technique. Proper graft selection is an important issue that is paramount to the evolution of ligament reconstruction surgery. Although the central third patellar tendon is presently the operation by which all new techniques must be compared, the use of nonautogenous grafts may complement arthroscopic reconstruction by allowing further reduction in surgical morbidity. In this article we have expanded on some of the advantages of arthroscopic ACL reconstruction, given an overview of arthroscopic techniques, and described the techniques we prefer.

Anterior Cruciate Ligament

Bracing for patellar instability.

Knee pain secondary to problems with patellar tracking is common. The initial treatment for these problems is conservative. Patellar orthotics have been used extensively to treat a variety of extensor mechanism problems. Millions of health care dollars are spent annually on the use of these braces. There are many different patellar orthotics on the market today. The use and design of most of these devices are unclear and often lack a solid biomechanical foundation. The practical mechanical function of these braces is to reduce the lateral displacement of abnormal patellofemoral tracking. Orthotics that are designed and tested using practical biomechanical principles for applying a medially directed force to the patella seem to have a role in treating patients with knee pain secondary to patellar malalignment and instability. Well-defined and controlled clinical studies of the use of patellar braces are lacking.
