Final answer:
Based on the description provided, the carpet layer is likely to be diagnosed with bursitis, particularly prepatellar bursitis, due to the nature of their job. Treatment would include rest, anti-inflammatory medications, and using knee pads to prevent further irritation.
Step-by-step explanation:
Diagnosis and Treatment for Knee Problems
The carpet layer presenting with left knee swelling, minimal tenderness to palpation (TTP), and no erythema or warmth, with no history of trauma, may be suffering from a job-related condition. Considering the repetitive nature of the work and no signs of erythema or trauma, the most likely diagnosis from the given options is bursitis, specifically prepatellar bursitis, which is common in individuals who perform tasks on their knees without protective gear. Tendinitis is another condition that is caused by repetitive movements, but it often presents with more localized tendon pain, which seems to be less consistent with the symptoms described.
Treatment for bursitis typically includes rest, anti-inflammatory medications, and protective measures such as knee pads to prevent further irritation. Severe cases may require aspiration of excess fluid or surgical intervention if it is chronic and unresponsive to conventional treatments. The runner's knee, or patellofemoral syndrome, is also associated with repetitive knee bending but tends to produce a dull ache around the front of the knee, which doesn't align as closely with the scenario described.
