We retrospectively evaluated the effectiveness of prolotherapy in resolving pain, stiffness, and crepitus, and improving physical activity in consecutive chondromalacia patients from February 2008 to September 2009. Sixty-nine knees that received prolotherapy in 61 patients (33 female and 36 male) who were 18-82 years old (average, 47.2 years) were enrolled. Patients received 24 prolotherapy in...

Background Patellofemoral pain is common, and treatment is guided by the presence and grade of chondromalacia. Purpose To evaluate and compare the sensitivity and specificity in detecting and grading chondral abnormalities of the patella between proton density fat suppression (PDFS) and T2 mapping magnetic resonance imaging (MRI). Study Design Cohort study; Level of evidence, 2. Methods A...

Patellofemoral pain syndrome (PFPS) [2] PFPS is a diagnosis of exclusion and is defined as pain behind or around the patella. It is synonymous with the term retro-patellar pain and has in the past been referred to as chondromalacia patellae. It is caused by compressive forces in the patellofemoral joint (PFJ). PFPS is very common. Symptoms are usually provoked by climbing or descending stairs, ...

and the controversy raging round this problem. Brooke (1937) of the 'Excision of Patella' fame recently followed up 54 of his cases treated 5 to 15 years previously. His faith in the efficiency of this operation was reiterated and reinforced as the result of this follow-up. An immediate controversy followed the appearance of this paper in which Max Page (1946), Bankart (1946), Tippett (1946)" a...

We present a case of superior dislocation of the patella trapped by interlocked osteophytes. Unlike previous reports, in which the mechanism resulted from a blow to the inferior pole, it is postulated that increased load on the extensor mechanism, combined with patella alta and patellofemoral osteophytes, caused locking of the knee in extension.

Bipartite patella is a common pathology, affecting 2% to 3% of the population. Usually these cases are bilateral and asymptomatic. However, a patient with a bipartite patella may complain of pain, which is most likely related to fragment mobility. Conservative treatment with physiotherapy, immobilization, and nonsteroidal drugs are encouraged during the initial 6 months following diagnosis. Thi...
