Objective: Patellofemoral pain syndrome (PFPS) is a condition that is characterized by patellar discomfort or pain that is aggravated during certain activities such as ascending/descending stairs. The Patellofemoral Disability Index (PDI) was developed to assess the effect of pain on functional activities in individuals with PFPS. The objectives of the current study were to determine the internal consistency, test-retest reliability, and validity of this index. Design: Cross-sectional study. Methods: Forty-one subjects who had PFPS with a mean age of $28.8{\pm}5.0years$ and a mean body mass index of $25.6{\pm}4.7kg/m^2$ participated in the study. All subjects were concurrently enrolled in a clinical trial for which they were instructed to complete hamstring-resistance exercises for 4 weeks. Over the course of the intervention, they completed both the PDI and the Oswestry Disability Index (ODI) at baseline after two weeks, and after four weeks. Pearson correlation coefficient was used to assess the criterion validity. Cronbach's ${\alpha}$ was used to examine the internal consistency. Intraclass correlation coefficients with 95% confidence interval were computed to examine test-retest reliability. Results: Subjects' responses within both the PDI and the ODI yielded Pearson correlation coefficient values that were positive and highly significant (range, 0.73-0.97; p<0.001). There was a high level of internal consistency (Cronbach's ${\alpha}{\geq}0.8$), with the exception of stair climbing (Cronbach's ${\alpha}=0.65$). Intraclass correlation ranged from 0.87 to 0.92, indicating high levels of test-retest reliability. Conclusions: The PDI is a valid, reliable, and feasible method of assessing pain and functional ability in patients with PFPS.

본 연구는 무릎뼈의 변형된 접선 방향 검사 시 최적의 입사각에 대해 알아보고자 하였다. 실험은 Kyoto Kagaku사의 PBU-50 phantom을 이용하여 바로 누운 자세에서 넙다리뼈-정강뼈 각도(Femur-tibia angle, F-T angle)를 95°, 105°, 115°, 125°, 135°, 145°로 각각에서 X선 중심선과 정강뼈가 이루는 각도가 5~20° 되도록 5°씩 변경하여(62.5°, 67.5°, 72.5°, 77.5°, 82.5°, 87°, 87.5°) 무릎뼈 접선 방향 영상을 획득하였다. 영상분석을 위해 Image J를 이용하여 Congruence angle, Lateral patellofemoral angle, Patellofemoral index, 대조도 잡음비(Contrast to noise ratio, CNR)를 측정하였다. 통계 분석은 SPSS 22를 이용하여 일원배치분산분석과 대응표본 t-검정으로 Merchant method와 비교하였다. 연구 결과 Congruence angle의 경우 무릎 각도-X선 중심선의 입사각도가 105°-72.5°(20° 접선조사), 115°-72.5°, 77.5°(15, 20° 접선조사), 125°-82.5°(20° 접선조사), Lateral patellofemoral angle은 115°-72.5°, 77.5°(15, 20° 접선조사), 125°-72.5°(10° 접선조사), Patellofemoral index는 115°-72.5°(15° 접선조사), 125°-72.5°(10° 접선조사)에서 Merchant method와 유의한 차이가 없었다(p>.05). CNR의 경우 105°-67.5°, 72.5°(15, 20° 접선조사), 115°-67.5°, 72.5°, 77.5°(10, 15, 20°접선 조사)일 때 Merchant method와 차이가 없는 것으로 나타났다(p>.05). 본 연구의 결과를 통해 무릎뼈의 변형된 접선방향 검사 시 무릎 각도와 X선관의 입사각도를 각각 115°-72.5°(15° 접선 조사)로 설정함으로써 진단적 가치가 높은 영상을 획득할 수 있음을 확인하였다.

The purpose of this case report is to introduce a case of immediate results with TMJ balancing therapy (TBT) in the treatment of chronic patellofemoral pain (PFP). A 17-year-old female patient with 4-month-old chronic knee pain that was unresponsive to conventional treatment was treated with TBT for a total of 5 sessions. The primary outcomes were evaluated using the Numeric Rating Scale (NRS) and the Korean version of the Western Ontario and McMaster Universities Osteoarthritis Index (KWOMAC). Following the first treatment, the NRS decreased rapidly, and the KWOMAC improved after a total of five treatments. These findings suggest that TBT can be an effective pain management option for chronic PFP patients with temporomandibular joint malposition. However, as this study is a report of a single case, further research is necessary.

Background: Korean medicine treatment was assessed in patients with knee osteoarthritis (OA) according to subgroups of: sex, age, cause of knee OA, body mass index, hospitalization period, history, OA compartment, phenotype, and comorbidity. Methods: A retrospective review was performed of 122 inpatients who were admitted to the Hospital of Korean Medicine for Korean medicine treatment of knee pain, and were diagnosed with knee OA based on magnetic resonance imaging findings. Analysis of patient subgroups (sex, age, cause of knee OA, body mass index, hospitalization period, history, OA compartment, phenotype, and comorbidity) was carried out and treatments including acupuncture, cupping, pharmacopuncture, herbal medicine, chuna therapy, medicinal steaming therapy, manual therapy, and extracorporeal shock wave therapy were listed. The numeric rating scale (NRS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and 5-level EuroQol- 5 Dimension (EQ-5D-5L) scores were measured before and after treatment to assess the effects of treatment on pain and quality of life. Results: Seventeen males and 105 females were included in this study. Most patients were in their 60s. In the total study population, NRS, WOMAC, and EQ-5D-5L scores were improved statistically significant when comparing before and after treatment. The NRS and WOMAC scores improved statistically significant in the medial, patellofemoral, medial + patellofemoral, medial + lateral + patellofemoral compartment. Conclusion: Korean medicine treatment significantly reduced pain, stiffness, and physical dysfunction, and improved the quality of life of patients with knee OA, suggesting that it may be an effective alternative to the current conservative treatments.

Purpose: High tibial valgus osteotomy (HTO) is a well-established surgical procedure for patients with medial compartment osteoarthritis (OA) of the knee. The hybrid closed-wedge HTO (CWHTO) procedure permits extensive correction in patients with severe deformities or patellofemoral joint OA. The aim of this study was to report the short-term results in a consecutive series of patients treated with hybrid CWHTO. Materials and Methods: We retrospectively evaluated the clinical outcomes and radiographic parameters in 29 consecutive knees that underwent hybrid CWTHO to correct medial compartment OA at an average follow-up of 52.6 months. Clinical outcomes were assessed using the Lysholm score and knee scoring system of the Japanese Orthopedic Association (JOA). The Kellgren-Lawrence grading system and pre- and postoperative mechanical axis (MA), femorotibial angle (FTA), posterior tibial slope, and patella height were assessed. Results: The FTA and MA significantly changed from $180.7^{\circ}$ to $170.4^{\circ}$ and from $22.0^{\circ}$ to $60.2^{\circ}$, respectively. No significant differences were observed between the mean pre- and postoperative posterior tibial slope, Insall-Salvati ratio, or Caton-Deschamps index. The postoperative JOA and Lysholm scores significantly improved from 76.7 to 95.8 and from 58.8 to 90.2, respectively. Conclusions: Satisfactory outcomes can be achieved with hybrid CWHTO in patients with medial OA.
