Correlations of typical pain patterns with SPECT/CT findings in unhappy patients after total knee arthroplasty.

Purpose: The diagnostic process in patients after painful total knee arthroplasty (TKA) is challenging. The more clinical and radiological information about a patient with pain after TKA is included in the assessment, the more reliable and sustainable the advice regarding TKA revision can be. The primary aim was to investigate the position of TKA components and evaluate bone tracer uptake (BTU) using pre-revision SPECT/CT and correlate these findings with previously published pain patterns in painful patients after TKA.

Typical Pain Patterns in Unhappy Patients After Total Knee Arthroplasty.

Background: The primary aim of this study is to assess characteristics of pain in patients with ongoing pain after total knee arthroplasty (TKA). The secondary aim of this study is to identify specific pain patterns and link these to underlying pathologies.

Methods: A prospectively collected cohort of 97 painful primary TKA patients was retrospectively evaluated.

Cranioplasty following decompressive craniectomy: minor surgical complexity but still high periprocedural complication rates.

Cranioplasty following decompressive craniectomy is of low surgical complexity, so much so that it has become the "beginners" cranial case. However, these "simple" procedures may have high complication rates. Identification of specific risk factors would allow targeted intervention to lower the complication rates.
