Local examination revealed swelling of bilateral suprapatellar
region and knee joints (Figure 1A).
There was diffuse synovitis throughout the suprapatellar
The surgeons must be familiar with several arthroscopic insertions, including the anteromedial, the lateral suprapatellar
and posteromedial as well as the standard anterolateral approach.
A 47-year-old married Indian male orthopaedic surgeon presented in the emergency department at the Jeddah National Hospital on 7th August 2015 with the complaint of sudden onset of suprapatellar
pain and inability to extend the knee of the left lower limb.
Under the guide of an arthroscope, it was released from the inferior patella with a blunt needle drill in the following order: inner and outer groove, suprapatellar
bursa, bilateral retinaculum, patellar joint, intercondylar fossa, bilateral compartment, and adhes- ions between the femur and the quadriceps.
The bilateral suprapatellar
bursa (SPB), deep infrapatellar bursa (DIPB), popliteal bursa (PB), and retrocalcaneal bursa (RCB) were imaged and measured for analysis.
Synovial proliferation was observed in the suprapatellar
pouch and gutters of both sides, which were excised.
of the following positive signs: (1) patellar crepitus, (2) pain following isometric quadriceps femoris muscle contraction against suprapatellar
resistance (Clarke's sign), (3) pain following compression of the patella against the femoral condyles (patellar grind test), (4) tenderness upon palpation of the posterior surface of the patella or surrounding structures, and (5) pain following resisted knee extension.
Ultrasound illustrated biceps tenosynovitis and trochanteric bursitis bilaterally, and increased suprapatellar
fluid in right knee (Figure 1).
A second right knee arthroscopy was then indicated in March 2011, which showed a fungal plate covering the synovial membrane, especially in the suprapatellar
In total, 30 patients presented joint swelling associated with floating patella syndrome and 9 patients presented no swelling; 28 patients had cavernous suprapatellar
Plain radiograph images of the right hip did not show any abnormalities; the radiograph of the right knee showed suprapatellar
