Total knee arthroplasty (TKA) is offered to patients who have end-stage knee osteoarthritis to reduce pain and improve functional performance. Knee edema and pain deteriorate the patients' outcomes after TKA at early period. By quantifying the patients' early outcome deficits and their potential relationships to edema and pain may assist in the design of in-patient rehabilitation programs. The aim of this study was to investigate of the effect of knee swelling on early patients' outcomes after primary TKA.Background
Objectives
Kinesiophobia is simply defined as a fear of movement and physical activity. It can be seen in patients as a result of any injury, which results in pain or a fear of injury recurrence. It leads to decreased motion and disuse that may result in a chronic pain syndrome and decreased physical function. High levels of fear-avoidance have been found in subjects with total knee arthroplasty (TKA) and knee injuries, which predisposes them to the development of chronic pain conditions and seriously affect functional outcomes and their return to previous activity levels. However, the relationship between pain, kinesiophobia and performance-based outcomes in assessment of patients with TKA is unclear. The aim of our study was to investigate relationship between pain, kinesiophobia and performance-based tests in assessment of patients with TKA.Background
Purpose
Tigecycline, the first member of glycylcycline family, has effective antimicrobial activity against resistant and implant associated infectious organisms. The objectives of this study are to assess the compressive and tensile mechanical strength characteristics of tigecycline loaded bone cement and to compare them with vancomycin and daptomycin loaded bone cements which are used in prosthetic joint infections with resistant microorganisms. A control group without antibiotics and three antibiotic loaded bone cement groups with varying concentrations (1g, 2g and 3g vancomycin, 0.5g, 1g and 1.5g daptomycin and 50mg, 100mg and 150mg tigecycline) were prepared and tested according to ASTM F451 and ISO 5833 standards. Statistical analysis of the obtained data done by using LSD (least significant difference) and Bonferroni corrected Mann Whitney tests.Background
Methods
Revision total knee arthroplasties (rTKA) are performed with increasing frequency due to the increasing numbers of primary arthroplasties, but very little is known regarding the influence of muscle strength impairments on functional limitations in this population. The aim of this study was to assess relationship between muscle strength and functional level in patient with rTKA.Background
Objectives
Investigating the effects of femoral stem length on hip and knee muscle strength. The study included 20 patients having undergone total knee prostheses (TKP) due to coxarthrosis and 10 healthy subjects. Of the 20 patients, 10 underwent conventional TKP and 10 had Thrust Plate Prothesis (TPP). For the assessment of the patients’ muscle strength of operated and non-operated hips (Gl. medius and Gl. Maximus) and knees (Quadriceps Femoris-QF), the Hand-Held Dynamometer (HHD) was used.Purpose
Methods
The management of nonunion following high tibial osteotomy by total knee replacement (TKR) has been reported previously. We have extended the treatment to embrace cases with an infected high tibial osteotomy by performing an initial debridement with a period of antibiotic treatment followed by TKR. We have reviewed the results of seven knees in six patients with a mean follow-up of 40.5 months (20 to 57) after the staged TKR. At the latest follow-up, all the pseudarthroses had healed and there had been no recurrence of infection. The mean Hospital for Special Surgery knee score improved from 51.2 (35 to 73) to a mean of 91.7 (84 to 98) at final review. Management of nonunion following high tibial osteotomy with a TKR can be extended to infected cases when treated in two stages with a debridement and antibiotic therapy prior to TKR.
Seven children with a post-traumatic cubitus varus deformity were treated using the Ilizarov technique of distraction osteogenesis. The outcome was rated as excellent in each case and all were satisfied with the cosmetic appearance. No complications had been encountered by the latest follow-up at a mean of 66.7 months. This technique seems reliable for the treatment of such deformities, provided that it achieves full correction by gradual distraction. Nerve palsy and unsightly scars are avoided, and the range of movement of adjacent joints is preserved.
Patients with short congenital amputations below the elbow often function as if they have had a disarticulation of the elbow. We have reviewed the results in six patients who had lengthening of such stumps by the Ilizarov technique to improve the fitting of prostheses. The mean lengthening was 5.6 cm (3.4 to 8.4), and in two patients flexion contractures of the elbows were corrected simultaneously. Additional lateral distraction was used in one patient to provide a better surface on the stump. There were no major complications. All six patients were able to use their prosthesis at the latest follow-up after 39 to 78 months.
A 16-year-old boy was involved in an agricultural accident in which he sustained a large wound to the right arm and forearm. Radiological examination showed loss of the distal half of the humerus. A posterior splint was applied and after two months there was regeneration of the distal humerus including the articular portion. He was able to use his arm at five months. Twenty years later, he had a painless elbow and a 70° range of movement.
