Abstract

Single-photon emission computed tomography-computed tomography (SPECT-CT) is a highly sensitive tool for detecting bone metabolism. We determined whether subchondral bone metabolism, as indicated by SPECT-CT in the patellofemoral (PF) joint, predicts response to conservative management in middle-aged patients with chronic anterior knee pain (AKP), and whether SPECT-CT results correlate with arthroscopic assessments of chondral lesions in the PF joint. The study group comprised 74 middle-aged patients with chronic AKP. All of the patients underwent SPECT-CT, and the results were graded along a scale of 0 to 3°. After 8 weeks of conservative management, they were grouped as responders (n = 40) or non-responders (n = 34) according to symptom improvement. We compared the median scintigraphic uptake of the PF joint between the two groups, and evaluated the positive predictive value (PPV) of uptake for treatment response in each patient. In non-responders, cartilage condition was assessed during arthroscopy, and the correlation of scintigraphic uptake with severity of the chondral lesion was assessed. The median scintigraphic uptake in the patella was higher in non-responders than in responders (2 vs. 1). Among patients with higher patella uptake (grade 2 or 3), the PPV for non-response to conservative therapy was 62-67 %, whereas it was 24-25 % in patients with lower uptake (grade 0 or 1). Patella uptake corresponded strongly with arthroscopic assessment of patellar chondral lesions; the correlation was less strong for the femoral trochlea. Increased subchondral bone metabolism in the patella is associated with responsiveness to conservative therapy. SPECT-CT can benefit clinicians by predicting the treatment response from conservative management.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 July 2015.
All research outputs
#12,736,600
of 22,818,766 outputs
Outputs from BMC Musculoskeletal Disorders
#1,681
of 4,043 outputs
Outputs of similar age
#112,863
of 262,962 outputs
Outputs of similar age from BMC Musculoskeletal Disorders
#28
of 60 outputs
Altmetric has tracked 22,818,766 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,043 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.1. This one has gotten more attention than average, scoring higher than 57% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 262,962 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
We're also able to compare this research output to 60 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 53% of its contemporaries.
