Twenty-five knees with symptomatic lateral patellar instability after total knee arthroplasty (TKA) were treated by operative realignment. Causes of instability include errors in surgical technique, quadriceps imbalance, and trauma. Fourteen knees had proximal realignment, nine had combined proximal and distal realignment, and two had component revision. At an average follow-up period of 50 mon...

[Purpose] This study examined the effects of balance training by applying knee joint movements on muscle activity in male adults with functional ankle instability. [Subjects and Methods] 28 adults with functional ankle instability, divided randomly into an experimental group, which performed balance training by applying knee joint movements for 20 minutes and ankle joint exercises for 10 minute...

OBJECTIVE The purpose of this article is to review the clinical importance and MRI appearances of injuries to the posterolateral corner of the knee. CONCLUSION Injuries to the posterolateral corner structures of the knee can cause significant disability due to instability, cartilage degeneration, and cruciate graft failure. Becoming familiar with the anatomy of this region can improve one's a...

OBJECTIVE To analyze the anteroposterior displacement of the knee by means of stress radiography in individuals with unilateral anterior knee instability and relate to time of instability. METHODS Sixty individuals with intact knees (control group) and 125 patients with unilateral anterior instability (AI group) agreed to participate in the study. Gender, age, weight, height, age at injury, t...

Meniscal lesions often occur in association with anterior cruciate ligament (ACL) tears at the moment of injury or, secondarily, as a consequence knee instability. Both ACL and meniscus are associated higher risk osteoarthritis. Adequate treatment these reduces rate degenerative changes affected knee. should be addressed concomitantly reconstruction must oriented towards preserving meniscal tis...

Ab." We propose a knee instability detector for standing using two uni-axial accelerometers, tangentially placed on the upper leg. This detector may be used as a part of the finite state artificial reflex control strategy for paraplegic standing with minimal quadriceps stimulation, as proposed by Mulder et al. [l 21. The detection strategy was experimentally tested in two healthy subjects. Dete...
