Objective: The aim of this study was to evaluate the Anterior Knee Pain Scale in a cohort of adolescents being treated conservatively for patellofemoral pain using Rasch analysis. Design: This is a psychometric study. Setting: Physical therapy clinics of a large pediatric hospital in Columbus, Ohio (United States) Subjects: A total of 646 adolescent patients with patellofemoral pain (76% female, 14.6 ± 1.6 years old). Intervention: Not applicable. Main Measure: The Anterior Knee Pain Scale. Results: The median Anterior Knee Pain Scale score was 73 (interquartile range 64–81), with scores ranging from 7 to 100 on the 100-point scale. The Rasch person reliability for the Anterior Knee Pain Scale was 0.74 and the Cronbach’s alpha was 0.75, representing an acceptable person reliability. Principal component analysis revealed a ratio of 5.2:1 demonstrating acceptable unidimensionality of the Anterior Knee Pain Scale. A significant misfit was observed in the item “Abnormal Painful Kneecap Movements” (Outfit Means Square 2.74, Infit Means Square 1.41). Ordering of item responses was unsatisfactory as only five of the 13 items demonstrated appropriate distinction between each of the responses. There was no differential item functioning for sex or age for all items of the Anterior Knee Pain Scale, based upon the criterion of ⩾ 0.5 logit difference. Conclusion: The Anterior Knee Pain Scale does not meet interval-level measurement criteria and should be considered ordinal level data.

AbstractAnteromedial osteoarthritis (AMOA) is a common wear pattern in primary osteoarthritic knees. In patients with bone-on-bone disease, the most appropriate surgical intervention is still a matter of debate. Knee arthroplasty is a well-accepted treatment to relieve symptoms and regain function. Unfortunately, satisfaction is limited, especially related to activities. A cross-sectional study was performed among patients treated with total knee arthroplasty (TKA) and unicondylar arthroplasty (UKA) to determine if the osteoarthritis wear pattern or type of prosthesis affects knee-specific function scores and satisfaction related to activities. All UKA patients (N = 100) were treated for AMOA. Based on radiological assessment of the wear pattern, TKA patients were divided into two groups: TKA for AMOA (N = 68) and true TKA (N = 99). The Knee injury and Osteoarthritis Outcomes Score (KOOS), new Knee Society score (KSS), anterior knee pain scale, visual analog scales (VASs) for satisfaction about activities, and net promoter score were collected. After 2 years' follow-up, the anterior knee pain scale and VAS satisfaction showed significantly better scores for patients treated with TKA for AMOA compared with the true TKA group. Also in the KOOS subscales, some differences were seen in favor of the TKA for AMOA group. The new KSS was not in favor of a specific wear pattern, but patients with AMOA treated with UKA performed better on the symptoms subscale compared with patients treated with TKA. In conclusion, patients treated with TKA for AMOA showed better knee-specific function scores and satisfaction scores compared with patients treated with TKA for other wear patterns, and only slight differences were found between both the AMOA groups (TKA for AMOA and UKA). Thus, the radiologic assessment of wear patterns might be useful to take into account the shared decision-making process, when discussing expectations, timing, and outcomes with knee osteoarthritis patients considering knee arthroplasty. When AMOA is present, it might be beneficial to choose UKA over TKA.

Objectives: Arthroscopic lateral retinacular release in patellofemoral pain syndrome Comparing the amount of hemorrhage and times of release between electrocautery and a new techniques for arthroscopic lateral release with scissors Methods: 77 patients included in this prospective randomized controlled study. Inclusion Criteria: 1. Over the age of fourteen and have anterior knee pain syndrome 2. Tightness in lateral part of knee 3. Despite receiving conservative treatment for 6 months, patients who have anterior knee pain complaints Exclusion Criteria: 1. Diseases that prolong bleeding time 2. Drugs that prolong bleeding time 3. Abnormal APTT-INR levels 4. Patients underwent anterior cruciate reconstruction surgery 5. Patients underwent microfracture surgery 6. Patients underwent meniscus repair surgery 7. Patients underwent synovectomy -- Due to inflammatory diseases and synovial chondromatosis is excluded from the study. In this study 77 (25M 52W med age 50,14 ± 14,17 ) patients divided into three groups which was similar in age and sex. All patients underwent standard arthroscopic surgery for patellofemoral knee sydrome and meniscal debridement 1. Group 1 (Control) (n:10) LRL was preserved 2. Group 2 (Scissors) (n:33) LRL was released with Scissors 3. Group 3 (Electrocautery) (n:34) LRL was released with Electrocautery Results: There was no difference between the groups in terms of socio-demographic characteristics. All lateral ligaments releases were performed under tourniquet . The release is not considered to be complete unless the patella can be stood on its medial edge without difficulty . In all patients, surgery duration was recorded. To calculate the amount of bleeding the blood in the drainage tube was recorded for 24 hours after surgery. For 67 patients based on clinical examination at surgery and in the immediate postoperative period, all releases were felt to be adequate. For all groups total bleeding at 24 h postoperatively is the statistically same (p:0.850) . In first 8 hours the amount of bleeding is more in scissors group (p:0.002). Lateral release time is longer in electrocautery group (380 seconds) than in scissors group (24 seconds). In release with electrocautery sometimes we used additional techniques scissors and scalpel for enough release. There was no difference between groups in terms of complications such as deep vein thrombosis , hemarthrosis or severe complications. Conclusion: In this study the amount of bleeding was the same in the groups but surgery duration was longer in electrocautery group. Our new technique for intraarticular arthroscopy guided lateral retinacular release uses with scissors which is simple, effective, rapid, and have resulted a few surgical complications such as superficial skin infection which responds oral antibiotics. Electrocautery is difficult and needs experience.

Abstract Individuals with excessive internal hip rotation and knee valgus during functional movement often develop abnormal lateral patellar tracking, sometimes resulting in anterior knee pain. A configuration of currently available biofeedback instruments, including an electronic goniometer, can provide feedback on limb position, which is useful in correcting the knee valgus. The article reports on the use of this biofeedback system with three individuals with measurable knee valgus, producing a remediation of the limb angle in each case.
