“1. Constant left knee pains with walking, being unable to squat, run and not fully able to straighten his leg. 2. Occasional locking and giving way of the knee with associated swelling and wasting of the quadriceps muscle…”
“… the presence of very early degenerative changes in this knee would make very little difference to the prognosis following this injury and the major factor leading to the present and future disability in this case has been the acute trauma due to the accident.”
“1(1) Subject to the provisions of Schedule 1, a person has a disability for the purposes of this Act if he has a physical or mental impairment which has a substantial and long-term adverse affect on his ability to carry out normal day-to-day activities … Schedule 1 2-(1) The effect of an impairment is a long-term effect if – (a) it has lasted at least 12 months; (b) the period for which it lasts is likely to be at least 12 months; or (c) it is likely to last for the rest of the life of the person affected. (2) Where an impairment ceases to have a substantial effect on a person’s ability to carry out normal day-to-day activities it is to be treated as continuing to have that effect if that effect is likely to recur … 4-(1) An impairment is to be taken to affect the ability of the person concerned to carry out normal day-to-day activities only if it affects one of the following – (a) mobility; … (e) ability to lift, carry or otherwise move everyday objects; … 6–(1) An impairment which would be likely to have a substantial adverse effect on the ability of the person concerned to carry out normal day-to-day activities, but for the fact that measures are being taken to treat or correct it, is to be treated as having that effect. (2) In sub-paragraph (1) “measures” includes, in particular, medical treatment and the use of a prosthesis or other aid … 8–(1) Where – (a) a person has a progressive condition (such as cancer, multiple sclerosis or muscular dystrophy or infection by the human imuno-deficiency virus), (b) as a result of that condition, he has an impairment which has (or had) an effect on his ability to carry out normal day-to-day activities, but (c) that effect is not (or was not) a substantial adverse effect, he shall be taken to have an impairment which has such a substantial effect if the condition is likely to result in his having such an impairment.”
“(a) Severe (i) Serious knee injury were there has been disruption of the joint, gross ligamentous damage, lengthy treatment, considerable pain and loss of function and an arthrodesis or arthroplasty has taken place or is inevitable. (ii) Leg fracture extending into the knee joint causing pain which is constant, permanent, limiting movement or impairing agility and rendering the injured prone to osteoarthritis and the risk of arthroplasty. (iii) Less severe injuries than those in (a)(ii) above and/or injuries which result in a less severe disability. There may be continuing symptoms by way of pain and discomfort and limitation of movement or instability or deformity with the risk that degenerative changes may occur in the long term as a result of damage to the kneecap, ligamentous or meniscal injury or muscular wasting.”
“49. I do not suggest that judges should be a slave to the tables. There may well be special factors in particular cases. But the tables should now be regarded as the starting point rather than a check. A judge should be slow to depart from the relevant actuarial multiplier on impressionistic grounds or by reference to “a spread of comparable cases” especially when the multipliers were fixed before actuarial tables were widely used.”
“31. The methodology proposed in paragraphs 33 to 42 describes one method for dealing with contingencies other than mortality, which replaces that set out in earlier editions of the Ogden Tables. If this methodology is followed, in many cases it will be appropriate to increase or reduce the discount in the tables to take account of the nature of a particular claimant’s disabilities. It should be noted that the methodology does not take into account the pre-accident employment history. The methodology also provides for the possibility of valuing more appropriately the possible mitigation of loss of earnings in cases where the claimant is employed after the accident or is considered capable of being employed. This will in many cases enable a more accurate assessment to be made of the mitigation of loss. However there may be some cases when the Smith v Manchester Corporation or Blamire approach remains applicable or otherwise where a precise mathematical approach is inapplicable. 32. The suggestions which follow are intended as a ‘ready reckoner’ which provides an initial adjustment to the multipliers according to the employment status, disability status and educational attainment of the claimant when calculating awards for loss of earnings and for any mitigation of this loss in respect of potential future post-injury earnings. Such a ready reckoner cannot take into account all circumstances and it may be appropriate to argue for higher or lower adjustments in particular cases. … However, the methodology does offer a framework for consideration of a range of possible figures with the maximum being effectively provided by the post-injury multiplier assuming the claimant was not disabled and the minimum being the case where there is no realistic prospect of post-injury employment.”
