Radiographic assessment in patellar instability and chondromalacia patellae.

چکیده
Minor degrees of malalignment of the patella and anatomical abnormalities including a flattened sulcus angle and an increased ratio between patellar tendon length and patellar length (PT:P) have been suggested as predisposing factors in the causation of chondromalacia patellae, as well as patellar instability. In order to confirm or refute this hypothesis a prospective study has been performed comparing the congruence and sulcus angles and the PT:P ratio in a group of 35 patients with chondromalacia confirmed by arthroscopy and a group of 33 patients with instability, with those of a group of 50 knees in normal volunteers. While there was a statistically significant correlation between an increased sulcus and congruence angle and a high-riding patella in patients with instability, no correlation could be identified in patients with idiopathic chondromalacia.

Increased serum cartilage oligomeric matrix protein levels and decreased patellar bone mineral density in patients with chondromalacia patellae.
BACKGROUND Chondromalacia patellae is a potentially disabling disorder characterised by features of patellar cartilage degradation. OBJECTIVE To evaluate markers of cartilage and bone turnover in patients with chondromalacia patellae. METHODS 18 patients with chondromalacia patellae were studied. Serum cartilage oligomeric matrix protein (s-COMP) and bone sialoprotein (s-BSP) levels were me...
متن کاملPatella alta and chondromalacia.
The Insall-Salvati method of determining the position of the patella by radiography was employed in fifty-one patients with chondromalacia patellae that had been proved at arthrotomy. There was no definite relationship between chondromalacia patellae and patella alta. There was, however, a highly significant statistical difference between the ratio of the length of the patella to that of the pa...

Chondromalacia of the patellae has been described as “ a degenerative process of the articular cartilage of the patella of traumatic origin, characterised by fibrillation. fissuring and erosion “ (Smillie 1962). Budinger (1906) is credited with the first description of this lesion. De Palma, in 1954, typified the current widespread opinion of the etiology of this condition: “ It is generally co...

BACKGROUND Recurrent dislocation of the patella in patients with below knee amputation is a known entity. Abnormally high-riding patella (patella alta) and medial patellofemoral ligament insufficiency in these patients predisposes them to patellar instability. The established treatment of this problem is surgical realignment. CASE PRESENTATION A 25 year old male patient with bilateral below k...
