Brief summary

The current study was conducted to estimate the prevalence of knee cap enthesitis in patients with knee osteoarthritis and its relation to knee function.

Detailed description

The current study will based on a cross sectional hospital-based survey, conducted among patients with knee osteoarthritis , Knee will assessed for the following items in both sides while Patient lying supine with the knee flexed 40 degrees: 1. Superior pole of the patella - quadriceps tendon enthesis: ● Quadriceps tendon thickness \>6.1 mm ● Suprapatellar bursitis ● Superior pole of patella erosion ● Superior pole of patella enthesophyte. 2. Inferior pole of the patella - proximal patellar ligament enthesis: ● Patellar ligament thickness \>4 mm ● Inferior pole of patella erosion ● Inferior pole of patella enthesophyte. 3. Tibial tuberosity - distal patellar ligament enthesis ● Patellar ligament thickness \>4 mm ● Infrapatellar bursitis ● Tibial tuberosity erosion ● Tibial tuberosity enthesophyte. Knee functional status was assessed using Knee injury and Osteoarthritis Outcome Score (KOOS) scale for Pain, other Symptoms, Activities of Daily Living (ADL), Sport and Recreation Function (Sport/Rec) and knee-related Quality of Life (QOL). Low knee function was considered if the patient had score 50 or more in any KOOS scale parameter.
