Abstract

The arthroscopic study of knee joint is of outstanding interest in assessment of knee complaints. The present article describes the results of arthroscopic examination of 100 patients (Mean age 29.4 years 82% male) evaluated from 1996 to 1997 in Imam Khomeini hospital of Tehran. Sport injury was the most prevalent cause of referral (40%). The 2 most frequent complaints were knee pain (94%) and tenderness (63%). Arthroscopic findings were pathologic changes of synovial fluid in 8, changes on articular surface of patella in 23, pathologic findings of femoral condyles and changes on articular surface of tibial plate in 24 cases. Other findings included plica in 18, tears of meniscus in 49, complete or partial tears of anterior cruciate ligament in 23 patients. Diagnostic accuracy of pre-arthroscopic clinical diagnosis was 88% and 93% for tears of meniscue and anterior cruciate ligament respectively. Arthroscopy of patellofemoral joint is an important adjunct to clinical and radiographic examination in diagnosis of knee complaints.

Abstract

Background: This cross-sectional study aims to evaluate the association between patellofemoral joint alignment measurements and patellofemoral cartilage defects using MRI images.
Methods: A retrospective and cross-sectional study was conducted on 530 knee MRI images from Golestan and Imam Khomeini hospitals in Ahvaz, Khuzestan, Iran. The images were obtained from individuals experiencing non-traumatic knee pain and were selected based on their age, with subjects over 30 years of age being included in the study. This survey was conducted over the period from March 2023 to March 2024. The parameters of femoral groove angle (SA), femoral groove depth (SD), lateral patellofemoral angle (LPFA), tibial-trochlear tubercle groove distance (TT-TG), lateral patellar displacement (LPD), patellar inclination angle, and patellar height were evaluated. In addition, the Caton-Deschamps index and the degree of focal cartilage defect (from 0 to III) in the knee joint were evaluated.
Results: Regarding body mass index, 15.7% of the patients studied were underweight, 42.3% were of normal weight, 31.1% were overweight, 10.4% were obese, and 0.6% were extremely obese. There was a significant relationship between body mass index and patellar-lateral articular cartilage defects in the lateral tibia and lateral femur. There was a significant relationship between age and patellar-lateral articular cartilage defects in the lateral femur. There was a significant relationship between lateral patellar articular cartilage defects and lateral patellar dislocation, lateral patellofemoral angle, tibial prominence-skeletal groove distance, and patellar inclination angle. In addition, there was a significant relationship between medial patellar articular cartilage defects and knee groove angle.
Conclusion: Patellofemoral misalignment is multivariately associated with knee articular cartilage defect. The results of this study will be of use to medical professionals, and the early diagnosis of knee osteoarthritis can prevent the development of the condition. It is recommended that similar studies and surveys be conducted in other provinces of Iran so that the statistical population is highly vulnerable.
