We report a prospective randomly controlled trial to examine the effectiveness of continuous passive motion (CPM) in improving postoperative function and range of movement after total knee arthroplasty (TKA). We allocated 53 patients (57 knees) to one of three postoperative regimes: no CPM (n = 19); CPM at 0 to 40° (0 to 40 CPM; n = 18); and CPM at 0 to 70° (0 to 70 CPM; n = 20). Those in the CPM groups had CPM for 48 hours and all patients had an identical regime of physiotherapy. There was an even distribution of various cemented and cementless TKAs in each group. Patients were assessed preoperatively and at one week and at one year postoperatively. At one week, there was a statistically significant increase in the range of flexion and total range of movement in the 0 to 70 CPM group compared with the no-CPM group. At one year we found no significant differences in mean flexion, overall range of movement,
Total femoral arthroplasty (TFA) is a rare procedure used in cases of significant femoral bone loss, commonly from cancer, infection, and trauma. Low patient numbers have resulted in limited published work on long-term outcomes, and even less regarding TFA undertaken for non-oncological indications. The aim of this study was to evaluate the long-term clinical outcomes of all TFAs in our unit. Data were collected retrospectively from a large tertiary referral revision arthroplasty unit’s database. Inclusion criteria included all patients who underwent TFA in our unit. Preoperative demographics, operative factors, and short- and long-term outcomes were collected for analysis. Outcome was defined using the Musculoskeletal Infection Society (MSIS) outcome reporting tool.Aims

Valgus knee deformity can present a number of
unique surgical challenges for the total knee arthroplasty (TKA)
surgeon. Understanding the typical patterns of bone and soft-tissue pathology
in the valgus arthritic knee is critical for appropriate surgical
planning. This review aims to provide the knee arthroplasty surgeon
with an understanding of surgical management strategies for the
treatment of valgus knee arthritis. Lateral femoral and tibial deficiencies, contracted lateral soft
tissues, attenuated medial soft tissues, and multiplanar deformities
may all be present in the valgus arthritic knee. A number of classifications
have been reported in order to guide surgical management, and a variety
of surgical strategies have been described with satisfactory clinical
results. Depending on the severity of the deformity, a variety of
TKA implant designs may be appropriate for use. Regardless of an operating surgeon’s preferred surgical strategy,
adherence to a step-wise approach to deformity correction is advised. Cite this article:
