Patellar tendinopathy
Meaning of patellar tendinopathy: For the purposes of this Statement of Principles, patellar tendinopathy: (a) means an acquired clinically symptomatic condition involving inflammation or degeneration of the patellar tendon; and (b) includes: (i) degenerative distal quadriceps tendon tear or rupture; (ii) degenerative patellar tendon tear or rupture; (iii) distal quadriceps tendinitis or tendinopathy; and (iv) patellar tendinitis; and (c) excludes: (i) Osgood-Schlatter disease; (ii) patellar tendon enthesopathy; (iii) patellar tendon lateral femoral condyle friction syndrome (Hoffa fat pad impingement syndrome); and (iv) Sinding-Larsen-Johansson syndrome.
Reasonable Hypothesis (RH) — Statement of Principles No. 21 of 2020
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting patellar tendinopathy or death from patellar tendinopathy with the circumstances of a person's relevant service:
- (1)running or jogging an average of at least 30 kilometres per week for at least the four weeks before the clinical onset of patellar tendinopathy;
- (2)undertaking weight bearing exercise involving jumping or repeated flexion and extension of the affected knee, at a minimum intensity greater than six METs for at least four hours per week, for at least the four weeks before the clinical onset of patellar tendinopathy;
Note: MET is defined in the Schedule 1 - Dictionary.
- (3)increasing the frequency, duration or intensity of weight bearing activity involving the affected knee by at least 100 percent, to a minimum intensity of five METs for at least two hours per day, within the seven days before the clinical onset of patellar tendinopathy;
Note: MET is defined in the Schedule 1 - Dictionary.
- (4)having direct trauma to the patellar tendon of the affected knee at the time of the clinical onset of patellar tendinopathy;
- (5)having gout of the patellar tendon or distal quadriceps tendon at the time of the clinical onset of patellar tendinopathy;
- (6)being treated with a glucocorticoid drug as specified before the clinical onset of patellar tendinopathy;
Note: being treated with a glucocorticoid drug as specified is defined in the Schedule 1 - Dictionary.
- (7)being treated with a fluoroquinolone antibiotic within the 60 days before the clinical onset of patellar tendinopathy;
- (8)for distal quadriceps tendinopathy or rupture only, being treated with atorvastatin for at least three months within the one year before the clinical onset of patellar tendinopathy;
- (9)for patellar tendon or distal quadriceps tendon rupture only: (a) having diabetes mellitus at the time of the clinical onset of patellar tendinopathy; or (b) having chronic renal failure at the time of the clinical onset of patellar tendinopathy;
Note: chronic renal failure is defined in the Schedule 1 - Dictionary.
- (10)running or jogging an average of at least 30 kilometres per week for at least the four weeks before the clinical worsening of patellar tendinopathy;
- (11)undertaking weight bearing exercise involving jumping or repeated flexion and extension of the affected knee, at a minimum intensity greater than six METs for at least four hours per week, for at least the four weeks before the clinical worsening of patellar tendinopathy;
Note: MET is defined in the Schedule 1 - Dictionary.
- (12)increasing the frequency, duration or intensity of weight bearing activity involving the affected knee by at least 100 percent, to a minimum intensity of five METs for at least two hours per day, within the seven days before the clinical worsening of patellar tendinopathy;
Note: MET is defined in the Schedule 1 - Dictionary.
- (13)having direct trauma to the patellar tendon of the affected knee at the time of the clinical worsening of patellar tendinopathy;
- (14)having gout of the patellar tendon or distal quadriceps tendon at the time of the clinical worsening of patellar tendinopathy;
- (15)being treated with a glucocorticoid drug as specified before the clinical worsening of patellar tendinopathy;
Note: being treated with a glucocorticoid drug as specified is defined in the Schedule 1 - Dictionary.
- (16)being treated with a fluoroquinolone antibiotic within the 60 days before the clinical worsening of patellar tendinopathy;
- (17)for distal quadriceps tendinopathy or rupture only, being treated with atorvastatin for at least three months within the one year before the clinical worsening of patellar tendinopathy;
- (18)inability to obtain appropriate clinical management for patellar tendinopathy;
Aggravation-only factors: the factors in subsections 9(10) to 9(18) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
Balance of Probabilities (BoP) — Statement of Principles No. 22 of 2020
11 factors
At least one of the following factors must exist before it can be said that, on the balance of probabilities, patellar tendinopathy or death from patellar tendinopathy is connected with the circumstances of a person's relevant service:
- (1)running or jogging an average of at least 60 kilometres per week for at least the four weeks before the clinical onset of patellar tendinopathy;
- (2)undertaking weight bearing exercise involving jumping or repeated flexion and extension of the affected knee, at a minimum intensity greater than six METs for at least six hours per week, for at least the four weeks before the clinical onset of patellar tendinopathy;
Note: MET is defined in the Schedule 1 - Dictionary.
- (3)increasing the frequency, duration or intensity of weight bearing activity involving the affected knee by at least 100 percent, to a minimum intensity of five METs for at least four hours per day, within the seven days before the clinical onset of patellar tendinopathy;
Note: MET is defined in the Schedule 1 - Dictionary.
- (4)having direct trauma to the patellar tendon of the affected knee at the time of the clinical onset of patellar tendinopathy;
- (5)having gout of the patellar tendon or distal quadriceps tendon at the time of the clinical onset of patellar tendinopathy;
- (6)running or jogging an average of at least 60 kilometres per week for at least the four weeks before the clinical worsening of patellar tendinopathy;
- (7)undertaking weight bearing exercise involving jumping or repeated flexion and extension of the affected knee, at a minimum intensity greater than six METs for at least six hours per week, for at least the four weeks before the clinical worsening of patellar tendinopathy;
