Background: This study aimed to use the muscle energy technique (MET) with total knee replacement (TKR) during the chronic phase in a clinical setting and confirm its effects on the knee extensor strength and ROM, balance, and walking ability. Methods: A total of 20 female patients who underwent TKR 1~4 years ago were assigned to two groups (Control: Q setting exercise+general physical therapy, n=10; Exp: MET+general physical therapy, n=10). Interventions were performed three times a week for 4 weeks. The strength of the knee extensor was evaluated using an aneroid sphygmomanometer, and ROM was evaluated using degrees at the end range on active knee flexion. The main balance outcomes were evaluated using two standard scale (TSS) and timed up and go (TUG) test, whereas the walking ability was evaluated using the 10 meter walk test (10MWT). Results: Analysis showed that both groups had significant increases in strength, ROM, TSS, TUG, and 10MWT. Differences in all variables were significant between the control and Exp groups at the post-intervention evaluation (p<.05). However, no significant difference was observed in strength and TUG. Conclusion: Results of this study demonstrated that MET would help improve the strength, ROM, balance, and walking ability of patients with chronic TKR who want to enhance their abilities and performance in activities of daily living.

류마티스성 관절염 등의 관절 질환이나 내반 변형 등을 동반한 환자에게 정형외과적으로 인공슬관절 치환술을 시행하는데 수술용 금속정을 삽입할 때 대퇴체부의 휨 정도로 인해 대퇴피질부에 손상을 주거나 2차 골절 등의 부작용을 유발하기도 한다. 이때 대퇴체부의 중심 좌표값을 알면 금속정이 해부학적 모양의 중심으로 삽입될 수 있어 이러한 부작용을 예방할 수 있을 것이다. 본 연구에서는 인공슬관절 치환술이 필요한 10명의 환자와 대퇴골 질환이 없는 정상군 10명의 대퇴부 단층촬영영상을 이용하여 3차원 좌표값을 찾은 후 Matlab을 이용하여 중심좌표값을 찾아 해부학적 모양을 반영한 그래프를 얻었고, 구간별 3차원 곡률반경 값을 구하였다. 그 결과 실험군의 대퇴골 평균 곡률반경과 표준편차는 $758.15{\pm}206.3mm$로 측정되었고, 정상군은 $1672.97{\pm}395.6mm$로 측정되었다. 측정된 결과는 통계적 유의성 확보를 위해 f-검정을 실행하여 두 집단간 평균의 차이를 검증하였다. 이 결과로 미루어 실험군의 대퇴체부 휨 정도가 더 심함을 확일할 수 있었으며 이러한 영상 분석방법을 이용하여 해부학적 중심점을 찾는다면 인공슬관절 치환술 같은 정형외과적 수술에 도움이 될 것이라 사료된다.

Purpose: The purpose of this study was to compare the effects of continuous passive motion(CPM) and continuous active motion(CAM) on proprioception of the knee after total knee replacement(TKR). Methods: Twenty patients with TKR were randomly allocated into two groups, the CPM group(n=10) and the CAM group(n=10). All subjects were evaluated for levels of pain, passive range of motion and angle reproduction of the knee. An angle reproduction test was used to assess the proprioceptive deficit. Two types of angle reproduction test were used: a passive angle reproduction(PAR) test and an active angle reproduction(AAR) test. The relevant examinations were performed before and after intervention(on the 5th day and the 10th day). The statistical significance were calculated using a t-test and a one-way repeated ANOVA. Results: A pre-intervention significant difference was not found between the two groups. Significantly better results were before and after the intervention at 10 days, for the PAR(flexion direction) test; however, only in the CAM group. There were no significant difference, either before or after the intervention, for the AAR test(flexion and extension direction) in both group. Both groups experienced similar levels of pain and passive range of knee motion before and after the intervention. Conclusion: This study revealed that CAM was a better effect to restore position sense of the knee joint after TKR.

The objective of this study is to propose a Korean medical rehabilitation protocol for total knee replacement (TKR) and to report its effectiveness. This study was conducted as a retrospective study which analyzes the medical records of 4 patients undergoing Korean medical rehabilitation with protocol and continuous passive motion exercise for more than two weeks after TKR. We evaluated the outcome checking physical examination findings of the knee joint, numeric rating scale (NRS), Lysholm knee score (LKS) and walking state. After the treatment, we observed that the function of knee joint, NRS, LKS, walking state of patients were improved. This study showed that Korean medical rehabilitation protocol has effect on knee joint recovery after TKR. The limitation of this study was the insufficient number of cases and short-term follow up. Further studies should be done steadily to report the effectiveness of a Korean Medical rehabilitation protocol for TKR.

Purpose: The purpose of this study was to investigate pain relief and functional recovery after total knee replacement. Methods: The treatment was performed by dividing individuals into a control group ($n_1=5$), ultrasound treatment group ($n_2=5$), and micro-current treatment group ($n_3=5$). The control group applied the hot pack for 15 minutes, Transcutaneous Electrical Nerve Stimulation (TENS) for 15 minutes, and Continuous Passive Movement (CPM) for 40 minutes. The ultrasound therapy group applied the frequency of 1 MHz, intensity of 1.0 $W/cm^2$ for five minutes following the same treatment as the control group. The micro-current therapy group applied the intensity of 25 ${\mu}A$, and pulsation frequency 5 pps for 15 minutes following the same treatment as the control group. After treatment, Visual Analogue Scale (VAS), Korean Western Ontario and McMaster Universities Arthritis Index (K-WOMAC), Berg Balance Scale (BBS), Range of Movement (ROM) and wound length was measured. Results: VAS showed significant effect in the control group and micro-current therapy group during the treatment period. According to the treatment of K-WOMACK, BBS, ROM, and Healing wounds showed main effects between groups. Conclusion: According to the results of this study, data showed improvement of pain relief, wound healing effects, and range of motion recovery. Thus, these selected treatments were effective after total knee replacement. In other words, electrical treatment continues to influence pain relief and functional recovery after total knee replacement.

Background: Total knee arthroplasty (TKA) recovers the alignment of the knee joint, but fails to automatically restore the alignment and function of the hip and ankle joints. It may affect the alignment and stability of the knee joint, therefore therapeutic intervention in hip and ankle joint is necessary for the rehabilitation process after TKA. Objects: The aim of this study was to comparison of the effects of the two exercise methods on the coronal plane alignment after TKA. This study conducted an experiment by dividing subjects into a lower extremity isometric co-contraction group (LEIC) and a quadriceps isolated isometric contraction (QIIC) group. Methods: A total of 37 subjects were randomly assigned to the LEIC ($n_1$=19) or the QIIC ($n_2$=18). Exercise was applied to five times per week for three weeks, starting on the eighth day after surgery. Range of motion exercises were performed as a common intervention and then each group performed quadriceps isometric contraction exercises with 10 sets of 5 repetitions. Radiological imaging was performed prior to surgery, one month and six months after surgery. In addition, the hip-knee-ankle angle (HKA) and tibiotalar angle (TTA) were measured. Results: The HKA was close to neutral in the LEIC rather than the QIIC (p<.05). The LEIC showed varus and the QIIC exhibited valgus TTA (p<.05). In a comparison of HKA and TTA over time, there was no significant change in either group (p>.05). According to the comparison of the TTA before surgery, the LEIC showed significant changes in the varus direction (p<.05), while there was no significant change in the QIIC (p>.05). Conclusion: The LEIC method triggered changes in the TTA and brought the HKA close to the neutral. Thus, LEIC is more effective than QIIC in creating stability in the coronal plane alignment of the knee and ankle joints after TKA.
