BACKGROUND Failure rates of knee ligament surgery may be high, and the impact of osseous alignment on surgical outcome remains controversial. Basic science studies have demonstrated that osseous malalignment can negatively affect ligament strain and that realignment procedures may improve knee joint stability. HYPOTHESIS/PURPOSE The purpose of this review was to summarize the clinical evidenc...

Nonunion of an avulsion fracture of the anterior tibial spine is quite rare. It could be associated with significant instability of the knee as it involves the fixation of the anterior cruciate ligament. Some of the complications of this nonunion include pain in knee extension, loss of knee extension and a certain amount of anterior knee instability. So, loss of knee extension is often a direct...

Dislocation of revision total knee arthroplasty is a very rare, serious and difficult complication. Incidence of significant instability and dislocation following primary TKA ranged from 1% to 2% in the past ten years. This incidence has been lowered to 0.15% to 0.5% with the development of modern surgical techniques and posterior stabilized implants. It is very few reports have been published ...

BACKGROUND Fractures of the knee account for about 6% of all trauma admissions. While its management is mostly focused on fracture treatment, it is not the only factor that defines the final outcome. OBJECTIVES This study aimed to study objective and subjective outcomes after proximal tibial versus distal femoral fractures in terms of knee instability and health-related quality of life. PAT...

Rotating-hinge knee implants are used for revision total knee arthroplasty in patients with severe ligament instability and bone loss. This study evaluated the outcomes of a series of rotating-hinge knees. Thirty-one NexGen Rotating Hinge Knees (Zimmer, Warsaw, Indiana) were implanted in 29 patients (2 bilateral), with an average age of 72.8 years. Indications for surgery were aseptic loosening...

Fifty patients who underwent a MacIntosh repair for anterolateral instability of the knee have been reviewed after a mean follow-up of two and a quarter years. The repair abolished a positive anterolateral jerk test in 42 out of5O knees and at the time ofreview 37 patients (74 per cent) were involved in some form of active sport, having regained functional and clinical stability. The MacIntosh ...

We have reviewed 32 patients who sustained a substantial knee ligament injury during adolescence when their knee epiphyses were open. They were all treated non-operatively and re-examined and evaluated in detail after an average of eight years. There were 25 Grade II partial tears and seven Grade III complete tears. After Grade II injuries the functional results were excellent or good, though s...

Anterior cruciate ligament (ACL) injury is common in knee joint accounting for 40% of sports injury. ACL injury leads to knee instability, therefore, understanding knee stability assessments would be useful for diagnosis of ACL injury, comparison between operation treatments and establishing return-to-sport standard. This article firstly introduces a management model for ACL injury and the cont...
