“…However, it is very difficult to reach this desired level because the injuries are very complex. 6 Recognition of knee instability has acquired great importance, since a lack of diagnosis may induce severe sequelae, especially when several of these injuries are associated.…”

“…Posterior tibial tendon dysfunction (PTTD) is one of the most common causes of acquired flat foot deformity in adults, and results in significant morbidity due to the pain and development of secondary osteoarthritis 1,2. Multifactorial etiology has been proposed to explain tendon degeneration in PTTD, including trauma, anatomic disorders and mechanical factors as well as inflammatory and ischemic processes 3.…”

INTRODUCTION:Posterior tibial tendon dysfunction is a common cause of adult flat foot deformity, and its etiology is unknown. PURPOSE: In this study, we characterized the morphologic pattern and distribution of types I, III and V collagen in posterior tibial tendon dysfunction. METHOD: Tendon samples from patients with and without posterior tibial tendon dysfunction were stained by immunofluorescence using antibodies against types I, III and V collagen. RESULTS: Control samples showed that type V deposited near the vessels only, while surgically obtained specimens displayed type V collagen surrounding other types of collagen fibers in thicker adventitial layers. Type III collagen levels were also increased in pathological specimens. On the other hand, amounts of collagen type I, which represents 95% of the total collagen amount in normal tendon, were decreased in pathological specimens. CONCLUSION: Fibrillogenesis in posterior tibial tendon dysfunction is altered due to higher expression of types III and V collagen and a decreased amount of collagen type I, which renders the originating fibrils structurally less resistant to mechanical forces.

“…There are disagreements over the use of autografts versus allografts, as well as over whether the popliteofibular ligament should pass from the femur to the fibula (11,32,34) or from the tibia to the fibula. We believe that the popliteofibular ligament has to proceed from the femur to the fibula, but only with additional biomechanical and surgical results, with long-term follow-ups, will we be able to reach a conclusion regarding which of these methods is the best surgical technique.…”

“…A 2.0-cm-long suture was made in its free end, and the iliotibial tract was then divided into two bands of 1.5 cm each. One of the bands remained in Gerdy's tubercle, and a 2.0-cm-long suture was made in the other using the Kawano et al technique (16). …”

OBJECTIVE:The aim of this study was to evaluate the treatment of patients with chronic lesions in the posterolateral corner of the knee with reconstruction of the fibular collateral ligament, popliteus tendon and popliteofibular ligament and with autografts of the biceps femoris and fascia lata.METHOD:A total of 129 patients with injuries of the posterolateral corner of the knee that lasted for more than three weeks and were associated with the lesion of at least one of the cruciate ligaments were included. All of the patients were operated on consecutively in the same hospital between March 2004 and April 2009. Clinical evaluation using the Lyshom scale and the International Knee Documentation Committee (IKDC, item 4, assessment ligament) protocol was performed in 114 patients for whom there were complete data available.RESULTS:There was significant improvement in the Lyshom score and improved stability according to the IKDC protocol in the pre- compared to postoperative varus stress test at 30 degrees and the posterolateral rotation test.CONCLUSIONS:Surgical reconstruction of the posterolateral corner of the knee with biceps femoris tendon and fascia lata autografts is effective in stabilizing the posterolateral corner of the knee.
