Early methods of treating high-energy tibial plateau fractures by open reduction and internal fixation led to high infection rates and complications. Alternative treatment methods include minimally invasive techniques and implants, external fixator stabilisation (monolateral and circular) and temporary external fixation followed by delayed definitive surgery. A clear understanding of the different fracture types is critical in achieving optimum results with minimally invasive techniques. The Chertsey classification system is based on the direction of force at the time of injury and helps with surgical planning. There are three groups: valgus, varus or axial fracture patterns.

124 tibial plateau fractures have been surgically treated in our hospital since 1995; there were 62 valgus, 14 varus and 48 axial type fracture patterns. Seventy-nine underwent open reduction with internal fixation, and forty-five had an Ilizarov frame. For valgus fractures the average IOWA knee score was 88 if internally fixed or 86 with an Ilizarov frame, range of motion was 140 and 131 degrees and time to union was 81 versus 126 days respectively. Varus fractures had an IOWA score of 83 (ORIF) and 95 (Ilizarov), ROM of 138 and 130 degrees and time to union of 95 versus 82 days. For axial fractures the average IOWA knee score was 85 (ORIF) compared to 82 (Ilizarov), the ROM was 124 degrees for both groups and time to union was 102 days and 141 days respectively.

Deep vein thrombosis occurred in 9% of cases with an Ilizarov and one patient required a total knee replacement for painful post-traumatic osteoarthritis. The infection rate for those internally fixed was 2.5%, three patients required a total knee replacement and 2.5% suffered a DVT.

Our results are comparable to the literature and the Chertsey classification of tibial plateau fractures helps with surgical planning.

Patients undergoing total knee arthroplasty (TKA) experience significant post-operative pain. We report the results of a new comprehensive patient care plan to manage peri-operative pain, enable early mobilisation and reduce length of hospital stay in TKA.

A prospective audit of 1081 patients undergoing primary TKA during 2008 and 2009 was completed. All patients followed a planned programme including pre-operative patient education, pre-emptive analgesia, spinal/epidural anaesthesia with propofol sedation, intra-articular soft tissue wound infiltration, post-operative high volume intermittent ropivacaine boluses with an intra-articular catheter and early mobilisation. The primary outcome measure was the day of discharge from hospital. Secondary outcomes were verbal rating pain scores on movement, time to first mobilisation, nausea and vomiting scores, urinary catheterisation for retention, need for rescue analgesia, maximum flexion at discharge and six weeks post-operatively, and Oxford score improvement.

The median day of discharge to home was post-operative day four. Median pain score on mobilisation was three for first post-operative night, day one and two. 35% of patients ambulated on the day of surgery and 95% of patients within 24 hours. 79% patients experienced no nausea or vomiting. Catheterisation rate was 6.9%. Rescue analgesia was required in 5% of cases. Median maximum flexion was 85° on discharge and 93° at six weeks post-operatively. Only 6.6% of patients had a reduction in maximum flexion (loss of more than 5°) at six weeks. Median Oxford score had improved from 42 pre-operatively to 27 at six weeks post-operatively. The infection rate was 0.7% and the DVT and PE rates were 0.6% and 0.5% respectively.

This multidisciplinary approach provides satisfactory post-operative analgesia allowing early safe ambulation and discharge from hospital. Anticipated problems did not arise, with early discharge not being detrimental to flexion achieved at six weeks and infection rates not increasing with the use of intra-articular catheters.
