The peptide hormone relaxin, found in pregnant and non-pregnant females, has been shown to have collagenolytic effects on ligamentous tissue. Relaxin receptors have recently been identified on the human female anterior cruciate ligament (ACL). Relaxin may affect the load bearing properties of the female ACL and contribute to non-contact ACL injuries.The administration of recombinant relaxin±estrogen...
Previous in vitro studies have found high levels of antibiotic release in the days immediately following implantation of antibiotic loaded articulating spacers. However there are relatively few data describing the elution profile beyond this immediate period. This study was designed to measure if gentamicin levels continue to be clinically therapeutic after an extended period following in vivo implantation...
We report a case of compression fracture of anterior margin of medial tibial plateau and medial femoral condyle combined with the posterior cruciate ligament and posterolateral corner disruption. A thirty-seven-year old male had undergone the left knee injury 6 months before. The physical examination revealed positive posterior drawer test and tibial dial test, which evidenced the posterior cruciate...
Arthrogryposis is a non-progressive disorder with congenitally soft tissue contractures affecting two or more joints. It can be sporadic, or inherited in an autosomal dominant or recessive fashion. Typically, in the upper limb, the shoulder is in adduction and internal rotation, the elbow is in extension with a lack of skin crease, and the wrist is in flexion with ulnar deviation. In the lower limb,...
It has been reported that lateral meniscus tears, including posterior horn tears, stable radial flap tears, or peripheral or posterior third tears that are combined with an Anterior Cruciate Ligament (ACL) injury can be treated with being left in situ. However, our experience has shown that the tear patterns are not so simple. They can show complex configurations and the inner side can be lost in...
The tuberculosis prosthetic joint infection is a rare complication. We reported a case of tuberculosis prosthetic joint infection following total knee arthroplasty, and the infection was controlled without the removal of implant with the anti-tuberculosis drugs for 12 months and there has been no evidence of recurrence. Although the tuberculosis prosthetic joint infection is few of all prosthetic...
Most patellar fractures are transverse involving the central third. Open reduction and stabilization of transverse patellar fractures is indicated if there is more than 2–3 mm of fragment separation and/or articular incongruity. Arthroscopic-assisted reduction and stabilization of displaced fractures of the patella had been reported as an alternative to open technique.The aim of this study was to...
This study evaluates results following patellar resurfacing using trabecular metal (TM) patella in marked deficiency or weakness of patellar bone that precludes patellar resurfacing with a standard cemented patellar button. Ten consecutive patients undergoing primary (3 cases) or revision (7 cases) total knee arthroplasty with patella augmentation were evaluated at a mean follow-up of 45 months (range...
Unicondylar osteoarticular allografts (UOA) of the knee are mainly used after bone tumour resections for benign aggressive tumours or small malignant tumours with clearly defined margins. They are also used less often in large posttraumatic condylar defects. Between 1989 and 2004, 12 deep-frozen UOA reconstructions (in 11 patients) were performed at our Institute. The diagnosis was chondrosarcoma...
Pain during osteoarthritis (OA) of the knee does not necessarily correlate with the severity of the radiographic grade, and the mechanism of pain has not been completely clarified. The purpose of this study was to evaluate risk factors for pain in the knee OA using epidemiologic analyses.We evaluated 518 out of 4183 people over the age of 40 (156 males and 362 females) from Shinyoshitomi village,...
This study aimed to analyse whether the precision of a three-dimensional mobile image intensifier (ISO-C 3D) differs from conventional two-dimensional fluoroscopy and high resolution CT scan in a fracture model of the proximal tibia. A depression fracture of the medial plateau (AO/OTA 41-B2.3) was created in 12 formalin-fixed, human cadaver knees. The cartilage of the depression could be positioned...
Incomplete injuries (grade I or II) to the medial collateral ligament (MCL) of the knee are common and usually self limiting. Some patients complain of chronic medial knee pain following injury. We highlight the importance of anatomical investigation of these patients and evaluate a successful treatment technique.A consecutive case series of 34 patients with chronic pain following grade I/II MCL injury...
This study was designed to provide evidence that computer-navigated minimally invasive total knee arthroplasty (MIS CN-TKA) enables identical mechanical accuracy as conventional computer navigated total knee arthroplasty (CN-TKA) while reducing rehabilitation time and hospital stay of the patients. Two groups of 20 patients requiring total knee arthroplasty due to degenerative or posttraumatic knee...
Accuracy of implant positioning and precise reconstruction of leg alignment offers the best way to achieve good long-term results in total knee arthroplasty. Computer instrumentation was developed to improve the final position of the component and restore the mechanical axis. Current navigation systems use either optical or electromagnetic tracking. The advantage of the Electromagnetic (EM) navigation...
There is a high rate of patellofemoral complications following total knee arthroplasty. Optimization of the cement–bone interface by venting and suction of the tibial plateau has been shown to improve cement penetration. Our study was designed to investigate if venting the patella prior to cementing improved cement penetration.Ten paired cadaver patellae were allocated prior to resurfacing to be vented...
The aim of the study was to quantify the incidence and timing of venous thromboembolic events (VTE) after total knee replacement (TKR). Data from 5100 consecutive TKRs performed over 10 years were prospectively collected. Cases were reviewed to identify thromboprophylaxis given, the diagnosis of VTE, treatment and adverse outcomes. There were 3 deaths (0.059%) from pulmonary embolism (PE). Of 123...
We asked whether a high-flexion design implant improves patient functional outcomes or range of motion (ROM) after primary knee arthroplasty.We searched the major medical databases for randomized trials and comparison observational studies comparing high-flexion and conventional knee implants. After testing for publication bias and heterogeneity, the data were aggregated by random effect modeling...
