Abstract Aim The primary aim of this study is to determine whether there a change in patellar height after closure the tendon defect bone-patellar tendon-bone graft harvesting. secondary evaluate clinical and functional outcomes. Method A retrospective observational was conducted. Patients who were diagnosed with ACL injury underwent reconstruction using bone- tendon- bone technique from 2015 2...

BACKGROUND Disruption of anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. The choice of graft for (ACL) reconstruction remains controversial. This prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (BPTB) grafts and four-strand semitendinosus-gracilis (ST) grafts for ACL reconstruction over a 3-year follow-up interva...

Pressure on the sole of the foot inside three different types of plaster cast, used in treatment of fracture of the lower leg, was measured on six normal persons. No significant difference was found between these pressures in below-knee plaster, full length plaster including the thigh and patellar-tendon-bearing plaster. Only occasionally a relief in pressure was found in patellar-tendon-bearin...

Minor degrees of malalignment of the patella and anatomical abnormalities including a flattened sulcus angle and an increased ratio between patellar tendon length and patellar length (PT:P) have been suggested as predisposing factors in the causation of chondromalacia patellae, as well as patellar instability. In order to confirm or refute this hypothesis a prospective study has been performed ...

Repair of a ruptured patellar tendon is usually performed with the use of sutures that are passed through intraosseous tunnels within the patella. However, a number of caveats pertain to this method. The Beath pin may penetrate the articular surface or may unduly injure the quadriceps through multiple passes. The already injured patellar tendon may be overly shortened after debridement and inse...

Firstly, the way of implementing approximatively the initial rollback of the natural tibiofemoral joint (TFJ) in a total knee replacement (AEQUOS G1 TKR) is discussed. By configuration of the curvatures of the medial and lateral articulating surfaces a cam gear mechanism with positive drive can be installed, which works under force closure of the femoral and tibial surfaces. Briefly the geometr...

Influence of the infrapatellar fat pad resection in a synovectomy during total knee arthroplasty (TKA) was evaluated in patients with rheumatoid arthritis (RA). Our findings for 120 RA patients at 28 to 38 months after surgery showed that (i) a significant decrease in the number of patients with anterior aching discomfort despite a lower-lying patella was seen in patients with infrapatellar syn...

OBJECTIVE To compare long term outcome of highly active patients with anterior cruciate ligament ruptures treated operatively versus non-operatively. DESIGN We reviewed high level athletes with an anterior cruciate ligament rupture on either MRI or arthroscopic evaluation more than 10 years previously, who were treated conservatively. They were pair-matched with patients who had had an anteri...
