For many Australians, a diagnosis of knee osteoarthritis often leads to a cycle of expensive imaging and, frequently, unnecessary surgery. However, health experts are now urging a shift in focus toward evidence-based, non-surgical treatments, highlighting the success of patients like Louise Bainbridge, who managed her condition through exercise rather than the operating table.
The Shift Away from Imaging
Radiologist Dr. John de Campo warns that the current trend of ordering CT scans, ultrasounds, and MRIs for knee pain often results in "red-herring" findings. These scans can reveal structural changes that may be unrelated to a patient's actual pain, leading to unnecessary anxiety and premature surgical interventions. According to the Australian Commission on Safety and Quality in Health Care, diagnosis should primarily rely on clinical history and physical examination, with imaging reserved for specific cases where an X-ray is deemed necessary.
A Personal Success Story
Louise Bainbridge, 52, was told in her late 30s that her knee osteoarthritis was "serious" and that she would need to see a surgeon. Despite the grim prognosis, she chose a different path. Encouraged by an athlete friend, she swapped high-impact activities for cycling and heavy-weight training. Today, Bainbridge reports having "zero problems" with her knees, even successfully squatting 130 kilograms. She continues to maintain an active lifestyle, proving that surgery is not the only solution for managing joint health.
Prioritizing First-Line Treatment
With approximately 1.9 million Australians living with knee osteoarthritis, medical experts emphasize that exercise and weight management remain the most effective first-line treatments. Dr. Phoebe Holdenson Kimura, a GP and medical adviser to the commission, notes that only about one in 10 patients with the condition ultimately requires a knee replacement. As the number of knee replacement surgeries continues to rise, clinicians are being encouraged to reserve surgery for cases involving severe, long-standing pain and functional impairment, rather than relying on scan results that may not reflect a patient's true physical capability.
