Changes in Lower Extremity Joint Angles after Total Knee Replacement

Ⅴ. 결론 무릎관절 전치환술 후 초기에 선 자세에서 하지 관절의 각도를 경 과 기간과 수술 측과 비수술 측에 따라 측정하고, 수술 후 환자의 자세 변화를 알아보고자 하였다. 그 결과 수술 전 선 자세 에서 무 릎관절 비대칭이 수술 후에도 남아 있었으며, 이러한 현상은 수술 전 무릎관절 구축과 넙다리뒤근육의 긴장이 수술 후에도 계속 지 속되는 것으로 생각된다. 따라서 무릎관절 전치 환술(total knee replacement)을 시행한 환자에게 수술 후 초기 상태에서 물리치 료 시 운동치료 계획을 수립할 때에는 하지 관절의 구축 및 근육의 긴장을 고려한 운동치료프로그램을 적용하는 것이 필요할 것으로 생각된다.

Bone Mineral Density Changes after Total Knee Replacement in Women Over the Age of 65

Bone Mineral Density Changes after Total Knee Replacement in Women Over the Age of 65

2 Department of Orthopedic Surgery, Medical College of Ajou University, Suwon, Korea Background: There are few reports on bone mineral density (BMD) changes of axial bones after total knee replacement (TKR) due to severe osteoarthritis (OA) of the knee joint and its results are controversial. The purpose of our study was to measure the BMD changes of hip and spine in patients receiving TKR due to severe OA and to identify clini- cal factors relating BMD changes. Methods: Among 66 female patients above 65 years old who underwent TKR due to severe OA and checked preoperative BMD, 52 patients who checked 1 year follow up BMD were enrolled. We investigated the association of the BMD changes with bilaterality of operation, obesity, preoperative knee functional scores, bisphosphonate medication, and diagnosis of osteoporosis. Results: We found no correlation between BMD changes and bilaterality of operation, obesity, preopera- tive knee functional scores and diagnosis of osteoporosis. Spine BMD increased in non- treatment and bisphosphonate treatment group but total hip BMD significantly increas- ed in bisphosphonate treatment group. Conclusions: Bisphosphonate treatment for 1 year prevents early reduction of hip BMD just after TKR regardless osteoporosis diagno- sis. We considered that the bisphosphonate medication would be beneficial to preven- tion of later hip fracture in elderly patient receiving TKR due to severe OA of knee joints.

Bone mineral density changes after Total knee replacement in women over the age of 65

iv - 국문요약 - 65 세 이상의 여자환자에서 인공 슬관절 치환술 후 골밀도 변화 퇴행성 슬관절염으로 인공 슬관절 치환술을 시행한 65세 이상의 여자환자 중 수술시 골밀도 측정을 하고 1년 이상 골밀도 추시 검사를 시행한 환자 66명 중 수술 후 1년에 골밀도 측정을 시행한 52명을 대상으로 하였다. 수술 부위의 양측 성, 비만 정도, 수술 시 골다공증 여부는 인공관절 치환술 일년 후 골밀도 변화 에 영향을 주지 않았으나 수술 후 일년간 비스포네이트 치료를 한 경우에는 total hip 골밀도가 유의하게 증가하였다. 따라서 퇴행성 슬관절염으로 인공 슬관절 치 환술을 시행한 환자에서 비스포스포네이트 약물의 투여는 수술 후 초기 고관절 부위의 골밀도 감소를 예방할 수 있어 수술 후 비스포스포네이트 약물의 투여가 수술 당시의 골다공증 진단 여부에 관계없이 추 후 고관절 골절 예방에 유익할 것으로 사료된다.

Pulmonary and Cerebral Fat Embolism Syndrome After Total Knee Replacement

Pulmonary and Cerebral Fat Embolism Syndrome After Total Knee Replacement

Fat embolism syndrome is usually manifested as a mul- tiorgan disorder that typically involves the respiratory sys- tem, central nervous system, cardiovascular system, skin and eyes. Gurd and Wilson have suggested criteria for the diagnosis of fat embolism syndrome, with three major cri- teria including respiratory insufficiency, cerebral involve- ment, petechial rash and nine minor criteria such as pyrexia, tachycardia, retinal changes, jaundice, renal change, anemia, thrombocytopenia, increased erythrocyte sedimentation rate (ESR) and fat macroglobulinemia [9]. These investigators have suggested that at least two symptoms for the major cri- teria or one symptom for the major criteria and four symp- toms for the minor criteria must be present to diagnose the syndrome.

Influence of Interferential Current Therapy and Laser Therapy on Functional Recovery after Total Knee Replacement

Influence of Interferential Current Therapy and Laser Therapy on Functional Recovery after Total Knee Replacement

These devices have almost no risk or side effects and instead tend to minimize tissue damage during electrotherapy. 6 Interference current therapy mainly utilizes medium frequencies between 3000 Hz and 6000 Hz and causes an interference current in the range of 1 to 250 Hz at a desired treatment area by mixing two similar currents, such as 4000 Hz and 4100 Hz. 7 Interference current therapy is a widely used electric therapy that is reported to be effective for backache, musculoskeletal pain, joint pain, and pain due to fractures. 8 However, recent reports on the pain relief of interference wave therapy indicate that it differs from that of existing interference current therapy. Ward and Robertson 9 reported that pain relief is greater when using a frequency of 10 KHz, whereas Dermmink 10 found that the bipolar method using two electrodes caused a more accurate interference wave than using four electrodes. Hurley 8 et al. reported that an electrode attachment site is more effective for an attachment in accordance with spinal nerves than a pain site. These reports indicate that changes are needed to interference current therapy to improve its therapeutic effect. These differences compared to existing interference current therapy can be attributed to the fact that information on existing interference current therapy is mostly derived from clinical experience rather than from randomized double-blind studies, and some information comes directly from transcutaneous electrical nerve stimulation therapy.

A Study on Changes in Lower Limb Joint Angles during Stair Walking with High Heel

2. Experiment method 1) Measuring instrument (1) Kinematic measurement of lower limb joints The three-dimensional motion analysis device (Motion Analysis Corp, Santarosa, CA, US) used in this study consisted of eight infrared cameras to capture the three- dimensional trajectory data of markers attached to each lower limb of the subject. During stair walkingat a camera frame rate of 120Hz using the motion capture software Cortex 1.1.4.386, the subject’ s pelvic, hip, knee, and ankle movements were measured. The markers of the three- dimensional motional analysis device were attached using the Helen-Hayes market set. 21 markers were used in total while being attached to each side of the body except the sacrum. The attachment areas included the ASIS, PSIS, sacral, thigh, medial knee, lateral knee, shank, medial malleolus, lateral malleolus, heel, and the region between the second and third toes. The markers for the heel and the region between the second and third toes were attached above the shoe surface. 11

The Accuracy of Lower Extremity Alignment in a Total Knee Arthroplasty Using Computer-Assisted Navigation System

The Accuracy of Lower Extremity Alignment in a Total Knee Arthroplasty Using Computer-Assisted Navigation System

Since Campbell and Boyd first developed a mold hemi- arthroplasty in 1940, the procedure for a total knee arthro- plasty has advanced greatly with the development of new materials and the increasing understanding of the knee joint biomechanics. Along with the advances in the prosthetic hardware, the recent development of the computer and navi- gation systems has led to the introduction of robotic surgery and computer-assisted surgery 1,5,9,11,19) . The long-term sur- vival rate of a total knee arthroplasty after a 10-year follow up was reported to be 80% to 95% 7,14,17) . Various factors affect this long-term survival, the most closely related factor being the physiologic recovery of the leg alignment 8,16) . Upon a follow-up study of more than 8 years, the loosening rate

Effects of game-based balance training with constraint-induced movement therapy on lower extremity function and balance confidence levels in women with total knee replacement

Effects of game-based balance training with constraint-induced movement therapy on lower extremity function and balance confidence levels in women with total knee replacement

Pain after knee arthroplasty is closely related to the pas- sage of time. In the early days, pain in present in almost all patients but it tends to disappear with the passage of time [18]. In addition, the patient’s age, height, weight, and body mass index may be risk factors for infection, malnutrition, steroid use, long hospital care and diabetes, rheumatoid ar- thritis and psoriasis [19,20]. However, the personality and psychological state of the patient is also very important. In the present study, there was a significant difference in the amount of pre- and post-intervention pain between the groups over time, but no significant difference was found between groups. In this study, too, the center of mass was shifted during balance training using the Slalom Ski pro- gram. Because the legs must be used safely and effectively when moving the center of mass of the body, muscles are constantly used for the extension moment of the hips, knees and ankles, which assist to increase the strength of the ex- tension, and furthermore.

Changes in Bone Mineral Density of Both Proximal Femurs after Total Knee Arthroplasty

Changes in Bone Mineral Density of Both Proximal Femurs after Total Knee Arthroplasty

If a certain area of an object under loading shows a change in material property or mechanical property or mi- crostructure, the transmission of stress is changed. Chang- es of the knee, such as osteoarthritis or TKA would have an effect on the mechanical properties of surrounding regions. 13,14) Many studies have reported that knee osteo- arthritis influences bone strength of the proximal femur and patients with osteoarthritis usually have increased BMD in the femur neck. 15-18) In our study, preoperatively, BMD of the hip on the operative side was lower than on the nonoperative side in accordance with the study re- ported by Ishii et al. 7) However, no statistical differences were observed. Soininvaara et al. 6) reported that preopera- tive BMD of the proximal femur on the operative side was significantly lower than that of the contralateral side in all region of interests. Considering the results, degree of exercise restriction due to pain and limited range of mo- tion of the joint, degree of osteoarthritis, pain scale before operation, dominant-leg, individual demands in daily life, and discordance between BMD of the left- and right-hip were considered compositively. 19-22) Also, according to the results of our analysis, the fact that 83% of the nonopera- tive side showed Kellgren-Lawrence stage II or less (83%) should be considered, and there was a limit to the applica- tion of the result to severe osteoarthritis of both knees.

Subcutaneous Emphysema of Lower Extremity after Knee Arthroscopy

Kyoung-Jin Park, M.D., Eui-Sung Choi, M.D. , Yong-Min Kim, M.D., Dong-Soo Kim, M.D., Hyun-Chul Shon, M.D., Byung-Ki Cho, M.D., Ji-Kang Park, M.D., Seung-Myung Choi, M.D., and Hyeon-Jun Eun, M.D. Department of Orthopaedic Surgery, Chungbuk National University College of Medicine, Cheongju, Korea Subcutaneous emphysema of lower extremity is a rare disease entity. Crepitation and swelling on physical examination and gas on radiographs raise the concern of infection due to the presence of gas gangrene forming organisms. Therefore, delay of diagnosis and appropriate management can be a major predisposing factor for sepsis and further associated high mortality. We experienced a rare case of subcutaneous emphysema of the right lower extremity after knee arthroscopy; life-threatening infection was ruled out by physical examination and laboratory testing. The patient recovered uneventfully with conservative management. Therefore, we report on this case with a review of current literature.

Quality of life of persons after total knee replacement surgery

Quality of life of persons after total knee replacement surgery

The SF-36 PCS results showed that the slight OA group scored 1.5 and the severe OA group scored 6.4, indicating a considerable difference (p<0.01). However, in other re- search, the slight OA group scored 0.1 and the severe group scored −0.3 in SF-36 mental component summary (MCS), which indicates no significant difference. Compared to these results, in the current study, the group that did not re- ceive TKR scored 32.5 and those who had TKR operation scored 30.1 on the SF-36 PCS, therefore a significant differ- ence was observed (p<0.000). In a previous study, the groups who did not have TKR scored 39.2 while those who had TKR scored 38.8, with considerable differences (p<0.046). Compared to the previous research, both studies had differences in PCS scores. However, only this study ob- served for difference in MCS scores. This is attributed to the gap between the influence of the physical factors and psy- chological factors of OA. Thus, TKR is considered to have a positive effect on physical activity when performed in se- vere stages of OA.

Economic Burden of Periprosthetic Joint Infection Following Primary Total Knee Replacement in a Developing Country

Economic Burden of Periprosthetic Joint Infection Following Primary Total Knee Replacement in a Developing Country

The economic burden of PJI can be reduced by making health policies as well as implementing preventive measures to attenuate the risk of PJI. Knowledge of the cost related to PJI is necessary to optimize existing health re- sources in developing countries such as Pakistan. Although treatment protocols and guidelines exist to prevent the incidence of PJI following a joint replacement procedure, a more proactive, individualized approach may be necessary to sort out this issue. 16,17) There is a need to identify high- risk patients with proactive implementation of pre- and postoperative protocols in order to prevent this devastating complication, thereby reducing financial burden. Previous studies reported a number of evidence-based protocols, which have proven to be effective in reducing PJI such as the use of prophylactic antibiotics and negative pressure wound therapy on surgical incisions. 18,19) According to data from OECD (organization for economic cooperation and development), the U.S. spent 17.8% of its gross domestic product (GDP) on health care, while the average spend- ing level among all high-income countries was 11.5% of GDP. 20) On the other hand, the share of total public health expenditure in Pakistan as percentage of GDP is only 0.7%.
