Restoration of joint line in total knee arthroplasty (TKA) is important for kinematics of knee and ligamentous balance. Especially in revision TKA, it may be difficult to identify the joint line. The aim of this study is to define the relationship between
1. Fifty-nine patients with fractures of the medial
Abstract. The radiographic or bony landmark techniques are the two most common methods to determine Medial patellofemoral ligament (MPFL) femoral tunnel placement. Their intra/inter-observer reliability is widely debated. The palpation technique relies on identifying the medial
We performed a new operation for ulnar neuropathy caused by recurrent dislocation at the medial
The operation has the advantage of simplicity, and it avoids the slight danger of secondary cicatricial contracture of the nerve when it is transplanted anteriorly and implanted in muscle. There is a slight hazard from external injuries because the nerve is unprotected by the
Certain technical advances, such as flexible intramedullary fixation and bioreabsorbable implants, have further increased enthusiasm for surgical management of pediatric fractures.» (Flynn et al.). In the Paediatric Surgery Department biodegradable pins of solid polydioxanone (PDS) in management of paediatric fractures have been used since April 1986. PDS pins are too soft for the osteosynthesis in fractures with fragments under high tensile pressures. However, we have successfully carried out a large number of internal fixations in children’s elbows. This is based on accurate distribution of PDS pins and careful positioning of periostal sutures and the adjacent disrupted muscles. Our technique, as presented at the 2nd European Congress of Paediatric Surgery in Madrid in 1997, is to fix temporarily the repositioned fractured fragment with Kirschner’s metal wire. Following osteosynthesis with PDS, the protruding K-wire is left in place for seven days until the limb is safely immobilized. A total of 96 patients were operated. The purpose of the study is to compare osteosynthesis with PDS pins (Group A) with that of metallic K-wire (Group B). Each group consisted of 48 children. General characteristics (age, sex, and fracture types) were statistically the same (P >
0.05). In Group A, with children between 2 and 13 years, or 9.3 on average, 21 children were with the lateral condyle fractures (43.75%), 25 children with medial epicondyle fractures (52.08%), and 2 children with medial condyle fractures (4.16%). In Group B, with children between 2 and 14 years, or 8.7 on average, 26 children were with lateral condyle fractures (54.16%), 19 children with medial epicondyle fractures (39.58%), and 3 with medial condyle fractures (6.25%). The study excludes Milch Type II fractures of medial and lateral condyles. The results have been examined in the follow-up period of one, three, and six months of two different methods according to Flynn’s criteria. After statistical evaluation the differences obtained had no statistical significance (P >
0.05). However, satisfaction score (0 – 10) is significantly higher in Group A than in Group B for both parents and evaluators (P <
0.05). Both treatments exhibit good results with the exception that the use of metal osteosynthetic material requires another operation. If metal wires are used and cut just underneath the skin, protruding with local inflammation may appear. Proper use of PDS pins requires no further operation. This is to the benefit for both the patient and rehabilitation staff.
The objective of this study was to analyze the biomechanical effect of an implanted ACL graft by determining the tunnel position according to the aspect ratio (ASR) of the distal femur during flexion-extension motion. To analyze biomechanical characteristics according to the ASR of the knee joint, only male samples were selected to exclude the effects of gender and 89 samples were selected for measurement. The mean age was 50.73 years, and the mean height was 165.22 cm. We analyzed tunnel length, graft bending angle, and stress of the graft according to tunnel entry position and aspect ratio (ratio of antero-posterior depth to medio-lateral width) of the articular surface for the distal femur during single-bundle outside-in anterior cruciate ligament reconstruction surgery. We performed multi-flexible-body dynamic analyses with wherein four ASR (98, 105, 111, and 117%) knee models. The various ASRs were associated with approximately 1-mm changes in tunnel length. The graft bending angle increased when the entry point was far from the lateral

The posterior compartments of the knee are currently accessed arthroscopically through anterior, posteromedial or posterolateral portals. A direct posterior portal to access the posterior compartments has been overlooked due to a perceived high-risk of injury to the popliteal neurovascular structures. Therefore, this study aimed to investigate the safety and accessibility of a direct posterior portal into the knee. This cross-sectional study comprised a sample of 95 formalin-embalmed cadaveric knees and 9 fresh-frozen knees. Cannulas were inserted into the knees, 16mm from the vertical plane between the medial
Abstract. Introduction. Previous research has shown that, notwithstanding ligament healing, properly selected MCL reconstruction can restore normal knee stability after MCL rupture. The hypothesis of this work was that it is possible to restore knee stability (particularly valgus and AMRI) with simplified and/or less-invasive MCL reconstruction methods. Methods. Nine unpaired human knees were cleaned of skin and fat, then digitization screws and optical trackers were attached to the femur and tibia. A Polaris stereo camera measured knee kinematics across 0. o. -100. o. flexion when the knee was unloaded then with 90N anterior-posterior force, 9Nm varus-valgus moment, 5Nm internal-external rotation, and external+anterior (AMRI) loading. The test was conducted for the following knee conditions: intact, injured: transected superficial and deep MCL (sMCL and dMCL), and five reconstructions: (long sMCL, long sMCL+dMCL, dMCL, short sMCL+dMCL, short sMCL), all based on the medial
We evaluated the morphological changes to the ulnar nerve of both elbows in the cubital tunnel by sonography in a total of 237 children, of whom 117 were aged between six and seven years, 66 between eight and nine years, and 54 between ten and 11 years. We first scanned longitudinally in the extended elbow and then transversely at the medial
