Abstract

Background

Whilst the literature abounds with patient reported outcomes following total knee replacement (TKR) there is a paucity of literature covering objective functional outcomes. Awareness of objective functional outcomes following TKR is key to the consent process and relating it to pre-operative function enables a tailored approach to consent.

Objectives

Identify trends in a range of functional outcomes prior to and following TKR up to one year post-operatively.

A small proportion of patients have persistent pain after total knee replacement (TKR). The primary aim of this study was to record the prevalence of pain after TKR at specific intervals post-operatively and to ascertain the impact of neuropathic pain. The secondary aim was to establish any predictive factors that could be used to identify patients who were likely to have high levels of pain or neuropathic pain after TKR.

A total of 96 patients were included in the study. Their mean age was 71 years (48 to 89); 54 (56%) were female. The mean follow-up was 46 months (39 to 51). Pre-operative demographic details were recorded including a Visual Analogue Score (VAS) for pain, the Hospital Anxiety and Depression score as well as the painDETECT score for neuropathic pain. Functional outcome was assessed using the Oxford Knee score.

The mean pre-operative VAS was 5.8 (1 to 10); and it improved significantly at all time periods post-operatively (p < 0.001): (from 4.5 at day three to five (1 to 10), 3.2 at six weeks (0 to 9), 2.4 at three months (0 to 7), 2.0 at six months (0 to 9), 1.7 at nine months (0 to 9), 1.5 at one year (0 to 8) and 2.0 at mean 46 months (0 to 10)). There was a high correlation (r > 0.7; p < 0.001) between the mean VAS scores for pain and the mean painDETECT scores at three months, one year and three years post-operatively. There was no correlation between the pre-operative scores and any post-operative scores at any time point.

We report the prevalence of pain and neuropathic pain at various intervals up to three years after TKR. Neuropathic pain is an underestimated problem in patients with pain after TKR. It peaks at between six weeks and three-months post-operatively. However, from these data we were unable to predict which patients are most likely to be affected.

Purpose

To calculate the cost of investigation of a painful Total Knee Replacement (TKR) to the hospital trust and Primary Care Trust (PCT).

Method

28 patients, over a year period, with painful Total Knee replacements were collected. Costs were calculated only of those patients who had an improvement in their symptoms such that they no longer had a painful TKR. The numbers of appointments, number of serological and radiological investigations were calculated along with any further investigations such as aspirations and arthroscopies. Costs were calculated from hospital records and charges to the PCT. An average cost per patient of investigations was calculated

We describe our technique and the early results of compaction morselised bone grafting (CMBG) for displaced tibial plateau fractures using fresh frozen allograft. This technique has been performed by the senior author since July 2006 on eight patients.

Clinical and radiological follow-up was performed on seven remaining patients at an average 12 months (range 4–19) following surgery. One patient died of an unrelated cause three months following surgery. One patient underwent a manipulation under anaesthesia at three months for knee stiffness. One patient developed a painless valgus deformity and underwent corrective osteotomy at 15 months. The height of the tibial plateau on radiographs has been maintained to an excellent grade (less than 2 mm depression) in all but one patient.

CMBG using fresh frozen allograft in depressed tibial plateau fractures provides structural support sufficient to maintain the height of the tibial plateau, is associated with few complications in complex patients with large bone loss and has theoretical advantages of graft incorporation and remodelling.
