title: The management of knee pain in primary care: factors associated with consulting the GP and referrals to secondary care.
abstract: OBJECTIVE
  To investigate the treatment of knee pain in primary care and the factors associated with consulting general practitioners (GPs) and referrals to specialist services.
  
  
  METHODS
  Individuals with knee pain were identified through postal questionnaires sent to patients aged 50 and over from two GP practices in southeast London. Patients with knee pain were then invited to the department, where demographic, clinical and service use data were collected. Participants also completed measures of pain, function, handicap and illness beliefs.
  
  
  RESULTS
  From the 2940 questionnaires that were sent out, the response rate was 34%. Of these, 49% reported experiencing knee pain in the previous 12 months. Two hundred and thirty-one patients with knee pain attended the department. One hundred and thirty-four (58%) had seen their GP about their knee pain, with 50 (37%) referred on to specialist services. Compared with non-consulters, consulters had more severe disease and higher levels of disability and handicap, and believed the condition was more severe and had major consequences on their lives. Those referred to specialist care had higher levels of handicap and also believed the condition was more severe, with major consequences on their lives, than those not referred.
  
  
  CONCLUSIONS
  In this sample nearly half of those who reported knee pain had not seen their GP and were self-managing their condition. A mixture of physical, social and psychological factors predicted visits to GPs and rates of referral to secondary care. Patient perceptions about knee pain were important predictors of both consultations and referrals, highlighting the need to address both physical and psychosocial factors in relation to help-seeking.
