Objectives To assess the effectiveness of chuna manual therapy for patients with total knee arthroplasty. Methods We searched 9 electronic databases(KISS, NDSL, RISS, OASIS, KMBASE, Cochrane Library, PubMed, CNKI, Wangfang data) using the keywords 'total knee arthroplasty OR total knee replacement' and 'tuina OR chuna' to identify RCTs that investigated the effectiveness of Chuna manual therapy after total knee arthroplasty. Results 23 RCTs were selected based on inclusion criteria. The systematic review showed positive effect of using chuna manual therapy after total knee arthroplasty. Conclusions 23 studies reported that chuna manual therapy had significant effects on total knee arthroplasty. However, many studies were exposed to probable high risk of bias. Also, all of the studies were published in one overseas country. Therefore, further research is required using well-designed RCTs to support the effectiveness of chuna manual therapy.

Purpose: Patients with total knee arthroplasty (TKA) have impaired balance and movement control. Exercise interventions have not targeted these impairments in this population. This study aimed to investigate the effect of complex balance exercises on unstable ground, on the gait, balance, and daily living ability of patients with total knee arthroplasty. Design: Randomized controlled trial. Methods: The participants consisted of 30 patients placed into two groups of 15 each: a experimental group (complex balance exercise) and a control group (physical therapy exercise). Both group exercise was applied for 3 times a week for 30 minutes for four weeks. Force plate for balance ability and Timed up and go (TUG) test were the primary outcome measures. The secondary outcome measures included 10-m walk test (10MWT) and the daily living ability using the Knee Outcome Survey Activities of Daily Living scale (KOS-ADL). Results: The result of this study showed that the experimental group had a significant difference in TUG and 10MWT than the control group, and balance was significantly different in CEA, CPL, and CAV. There was a significant difference in daily living ability between the experimental and control groups. This study confirms that the physical therapy with complex balance exercise on unstable surfaces has positive effects on balance, gait and daily living ability in patients with total knee arthroplasty. Conclusion: As a result of this study, complex balance exercise on unstable surface was more effective in improvement gait, balance and daily living ability in total knee arthroplasty. From this study, physical therapy with complex balance exercises on unstable ground may be proposed as and effective intervention method for improving gait, balance, and daily living ability in patients with early total knee arthroplasty.

Purpose: The purpose of this study is to investigate the effects of interference current therapy and laser therapy on functional recovery after total knee arthroplasty by measuring the Berg balance scale and range of motion. Methods: Subjects were 30 patients who were admitted to G Hospital after total knee arthroplasty. They were randomly assigned to experimental group I in which interference current therapy was applied (n=10), experimental group II in which laser therapy was applied (n=10), or the control group (n=10). The Berg balance scale and range of motion of the subjects were measured before, after 2 weeks, and after 4 weeks of therapy. Results: There was a statistically significant change (p<0.05) in the Berg balance scale and range of motion before and after therapy intervention among the laser therapy group and the interference current therapy group. There was also a significant change between the groups in the Berg balance scale and range of motion. Tukey's post hoc comparison showed a statistically significant difference between the control group and experimental group I and between the control group and experimental group II (p<0.05). Conclusion: The application of interference current therapy and laser therapy resulted in a significant change in both the Berg balance scale and range of motion among patients with total knee arthroplasty. The findings of this study can be used as preliminary clinical data in evaluating functional recovery in patients with total knee arthroplasty in a post-clinic setting.

Purpose: This study was a qualitative research using focus group interviews to collect data on the health care providers' perceptions of physical function in older adults with arthroplasty from hip fracture. Methods: A total of 12 subjects participated in this study. In order to conduct focus group interviews, structured manuscript, field notes, visual recording, and debriefing notes were referred and thematic analysis was used in analysis phase. Results: The six themes were raised: 'burdensome client', 'health care providers' perception of functional decline in older adults after surgery', 'health care providers' perception of caregiver', 'medical environment perceived as affecting physical function', 'crucial components perceived as encouraging functional restoration', and 'difficulty of pain management' with 18 subthemes. Conclusion: Healthcare providers perceived functional decline of elderly after arthroplasty and identified points facilitating or disturbing physical function Moreover, various perspectives on pain management related to physical function were represented.

The demand for total knee arthroplasty (TKA) is rapidly increasing worldwide. The most common indication for TKA is osteoarthritis (OA); however, some patients with rheumatoid arthritis (RA) also undergo TKA. This study aimed to investigate the effects of RA on TKA. Our findings revealed that patients with RA underwent TKA at a younger age than did patients with OA. However, contrary to the findings of pre-21st century studies, the average age of TKA among patients with RA was not significantly different from that of patients with OA. Additionally, patients with RA had a 1.5-fold higher risk of undergoing TKA. Although not statistically significant, patients with RA had a higher revision TKA rate, a shorter time until revision TKA, and underwent more revision TKAs due to infections than did patients with OA. An analysis of factors that affect revision TKA revealed that the risk of revision increased if the erythrocyte sedimentation rate and C-reactive protein levels were increased at the time of TKA. This study showed that patients with RA have a slightly higher risk of undergoing TKA than did patients with OA. Furthermore, the presence of inflammation at the time of TKA increases the risk of revision; therefore, inflammation should be adequately controlled before performing TKA.

Objectives This study was conducted to evaluate the therapeutic effect of herbal medicine after total knee arthroplasty. Methods Key words such as total knee arthroplasty and herbal medicine were searched in 10 databases (Ovid-Medline, Ovid-EMBASE, Ovid-AMED, Cochrane Library, China National Knowledge Infrastructure [CNKI], National Digital Science Library [NDSL], Koreanstudies Information Service System [KISS], Oriental medicine Advanced Searching Integrated System [OASIS], KoreaMed, KMBASE), and only suitable randomized controlled trials (RCTs) were selected. Results 8 RCTs were finally selected, and herbal medicine showed positive results for pain relief and functional recovery after total knee arthroplasty. However, the analyzed 8 RCTs showed a high overall risk of bias. Conclusions In the future, RCTs with a higher level of evidence on the effect of herbal medicine after total knee arthroplasty need to be continuously conducted.

THRA(Total Hip Replacement Arthroplasty) has been widely used for several decades as a viable treatment of otherwise-unsolved hip problems. In THRA surgery, cement mantle thickness is critical to long-term implant survival of femoral stem fixed with cement. Numerous studies reported thin or incomplete cement mantle causes osteolysis, loosening, and the failure of implant. To analyze the effect of femoral stem rotation on cement thickness, in this study, we select two most popular stems used in THRA. Using CAD models obtained from a 3D scanner, we measure the cement mantle thickness developed by the rotation of a femoral stem in the virtual space created by broaching. The study shows that as the femoral stem deviates from the target coordinates, the minimum thickness of cement decreases. Therefore, we recommend development of a new methodology for accurate insertion of a femoral stem along the broached space. Also, modification of the stem design robust to the unintentional movement of a femoral stem in the broached space, can alleviate the problem.

Three dimensional numerical model based on the finite element method(FEM) were developed to predict the mechanical behavior of hip implants. The purpose of this study is to investigate the stress distribution of two types of cementless total hip replacement femoral component -a straight stem and a curved stem, and to compare their effect on the stress shielding between two types by three dimensional finite element method. The authors analyzed von Mises stress in the cortex & stem and compared the stress between the straight and the curved stem. In comparison of stresses between two different design of femoral stem, there was 25% more decrease of stress in straight stem than curved stem in the medial cortex at proximal region. The straight stem had consistently much lower stresses than the curved stem throughout the whole medial cortex with maximum 70% reduction of stress. However, there was little change in stress between nature and 2 implanted femur throughout the lateral cortex. Stress of femoral stem was much higher in the straight stem than the curved stem up to 60%. The straight stem had more chance of stress shielding and a risk of fatigue fracture of the stem compared with the curved stem in noncement hip arthroplasty. In design of femoral stem still we have to consider to develop design to distribute more even stress on the proximal medial cortex.

It is necessary to have a model that describes the feature of the knee Joint with a sufficient accuracy. Koreans, however, do not have their own knee joint model to be used in the total knee replacement arthroplasty. They have to use European or American models which do not match Koreans. Three-dimensional visualization techniques are found to be useful in a wide range of medical applications. Three-dimensional imaging studies such as CT(computed tomography) and MRI(magnetic resonance image) provide the primary source of patient-specific data. Three-dimensional knee joint models were constructed by image processing of the CT data of 10 subjects. Using the constructed model, the dimensions of Korean knee joint were measured. And this study proposed a three-dimensional model and data, which can be helpful to develop Korean knee implants and to analyze knee joint movements.
