Experimentally Induced Anterior Knee Pain Results In Altered Knee Joint Kinetics

A 41-year-old active (exercising >600 min per week) male without a surgical history complained of nine years of intermittent bilateral anterior knee pain after physical activity. He was diagnosed with bilateral chondromalacia (grade IV chondrosis) with plica syndrome, for which he underwent bilateral patella cartilage debridement with medial plica excision (additional removal of lateral retinaculum in the right knee). The patient then performed 12 weeks of an aggressive postoperative rehabilitation program. Each rehabilitation session consisted of disinhibitory modalities (sensory level of transcutaneous electrical stimulation and cryotherapy: focal knee joint cooling and cold-water immersion) and voluntary exercises (aerobic, resistance, and flexibility). During rehabilitation, pain perception, knee joint skin temperature and circumference, and functional outcome measures (Kujala anterior knee pain scale, International Knee Documentation Committee Score, and lower-extremity functional scale) were also recorded. While the patient’s pathology and surgical intervention were not extreme, progressions in the rehabilitation components and functional outcome measures in this clinical case could be used as a future reference for postoperative interventions. Additionally, surgery-induced inflammation seemed to last for four weeks.

Abstract Background The knee joint is one of the most commonly injured joints in the body. Because of its complex structure, this joint is subjected to numerous pathologies and due to the recent increase in various sport activities, there has been a parallel increase in sport-induced internal derangements of the knee. The main strength of knee MRI is the assessment of articular and Peri-articular diseases. The specific structures best suited for MRI assessment include tendons, muscles and ligaments, as well as peri-articular soft tissue masses. Objective The purpose of this study is to detect the accuracy of MR imaging as a diagnostic tool in the evaluation of different knee joint pathologies that cause anterior knee pain, with emphasis on some of their grades and types for better assessment. Methodology This study included 20 patients (6 female and 14 male). Their ages range between 10-60 years (average age 30 years). All presented by anterior knee pain and were referred to radiology department of Ain Shams University hospital or private centers for MRI examination after orthopedic consultation. Results 5% of the patients presented with anterior knee pain showed MRI evidence of patellar tendinopathy (66% below the age of 30 years and more in females). In all cases the hyperintense focal thickening was at the proximal third of the tendon, with the AP diameter of the patellar tendon greater than 8mm. In our results about 10% of the patients in the study sample, had MRI evidence of tear in the anterior horn of lateral knee meniscus with a female equal to male (50% females and 50% males). Cartilage injuries were detected in 5% of the study sample, showing male predominance (100% were male and 0% were female) with average age 32 years. All have a past history of trauma. Conclusion MRI is generally safe, accurate, and specific modality which has been proven to be the modality of choice in the diagnosis of different knee pathologies that cause anterior knee pain in different age groups. Also, it has a high specification in detecting the grades and types of some of these diseases.
