This retrospective study was undertaken to evaluate the outcome of primary total knee arthroplasty (TKA) performed from January 1986 to December 1997 at this institution. Case review included Knee Society scores and functional knee score. The records of 94 patients (128 knees) were available for analysis with the sample comprised of 76 females (80.9%) and 18 males (19.1%) and a mean age was 61.4 years. TKA was performed for osteoarthritis (OA) in 96 knees (75%) and rheumatoid arthritis (RA) in 32 knees (25

A case of traumatic posterior cruciate ligament (PCL) avulsion fracture presenting with unusual radiographic findings is described. CT scan of the right knee showed features suggestive of combined ACL and PCL avulsion fractures. Arthroscopic findings showed that the injury was in fact a PCL avulsion fracture that was displaced anteriorly so as to mimic an ACL avulsion fracture on CT scan.

We report a case of 29-year-old female who presented with
right heel pain that worsened over a period of two years. The onset of pain was followed by swelling at the medial aspect of right ankle. She was initially treated for plantar fasciitis with multiple steroid injections over the heel. Subsequent MRI revealed a well-defined heterogeneous lesion in continuity with the medial plantar nerve. Excision biopsy was performed and histopathological evaluation revealed monophasic synovial sarcoma. The patient subsequently underwent wide resection and free tissue transfer followed by radiotherapy and chemotherapy. This case highlights an unusual site and presentation of synovial sarcoma which led to delayed diagnosis and treatment.

Antibiotic-loaded bone cement has been used as prophylaxis against infection in total joint replacement surgery. Its effect on the mechanical strength of cement is a major concern as high dose of antibiotic was associated with a significant reduction in mechanical strength of bone cement. However, the cut-off antibiotic that weakens the mechanical strength of cement remains to be determined. This study was undertaken to observe the changes in the mechanical properties of bone cement with gradual increments of Cefuroxime antibiotic. Cefuroxime at different doses: 0, 1.5, 3.0 and 4.5gm were added to a packet of 40gm bone cement (Simplex P) and study samples were prepared by using third generation cementing technique. Mechanical impact, flexural and tensile strength were tested on each sample. Significant impact and tensile strength reduction were observed after addition of 4.5 gm of Cefuroxime. However, flexural strength was significantly reduced at a lower dose of 3.0 gm. The maximum dose of Cefuroxime to be safely added to 40mg Surgical Simplex P is 1.5gm when third generation cementing technique is used. Further study is needed to determine whether it is an effective dose as regards to microbiological parameters.
