Would you exclude a patient from PKR if they pointed to their pain being anterior/in the patella region, or over the lateral condyle?
Studies have shown that the perceived location of knee pain does not influence the outcome of an Oxford PKR 1-3 as long as the patient is suffering from AMOA.
According to Liddle et al. 1 there was no relationship between the pre-op location of pain and the outcome at 1 and 5 years. When comparing patients with medial pain with those complaining of pains elsewhere in the knee, they observed no difference in OKS, AKSS or pain scores at 1 or 5 years.1 Similarly, Hamilton et al. 3 showed that the pre-op location of pain did not influence outcome at 10 years either.
