The Use of bone allograft in orthopaedic Surgery has been predicted to increase particularly in joint revision surgery. This has led to a potential problem with supply. Questionnaires were distributed to all 146 Consultant orthopaedic Surgeons working in Scotland in 2000. They were asked to indicate their current usage of bone and tissue allograft, any problems encountered with supply and if alternatives to allograft such as processed bone, might be used. The questions asked were very similar to those asked in a survey by the author (GG) in 1995 to enable comparisons to be made. 74% of all bone issued by the SNBTS in 2000 –2001 was used in revision hip arthroplasy. This compares with only 66% of bone issued in 1998–1999.

Replies were received from 125 consultants (87%) of whom 93 reported using bone allograft. 41 consultants (46%) predicted an increase in their requirement for bone allograft, and 23 (26%) felt they could currently use more bone if this became available. Sixty percent of Surgeons would consider using processed bone as an alternative. In comparison with figures from a previous study in 1995, an increasing number of surgeons are prepared to use processed bone as an alternative to fresh frozen allograft. As the number of revision THR’ s continues to increase the amount of bone required is likely to continue to increase. The need to increase efficiency in harvest and supply of bone is therefore great. The use of more SNBTS nurses in selection of patients and collection of bone may increase efficiency. More surgeons may have to use processed bone, which would allow more bone to be released. Also processing may help reduce transmission of infective particles such as HIV and new variant CJD. With rising public and medical concerns over these issues this seems most desirable.

Purpose: In this study we intend to evaluate the outcomes of patients with the Rotaglide prosthesis implanted for osteoarthritis.

Method: All patients reviewed had this prosthesis implanted for primary total knee arthroplasty in Cross-house hospital. The minimum follow up period was 5 years (range 5–8). Patients were assessed clinically and results were standardised using the Hospital for Specialist Surgery (HSS) knee score. Standard radiographs were taken in AP and lateral planes to assess for loosening. Case notes were then examined for evidence of complications in the peri and postoperative complications.

Results: Sixty seven patients (73 knees) were reviewed with the Rotaglide total knee replacement implanted for osteoarthritis. 94% of patients had an excellent clinical outcome with HSS scores of 85 or more. The average HSS score was 90.2. Two patients were revised, one for meniscal fracture and one for meniscal dislocation. Two patients were treated with anti-biotics for superficial wound infection.

Conclusions: We feel this prosthesis offers a safe and effective treatment for osteoarthritis with a good clinical outcome at 5 years with a low level of complications.
