Purpose of Study: To prospectively evaluate the outcome of single surgeon endoscopic anterior cruciate ligament (ACL) reconstruction with quadrupled hamstring tendons drilling femoral tunnel independent of the tibial tunnel.

Methods and Results: 28 patients underwent endoscopic ACL reconstruction by a single surgeon in a DGH setting. All patients had symptomatic ACL deficiency proven by either MRI or previous arthroscopy. All patients were prospectively scored using the International Knee Documentation Committee (IKDC) score, the Lysholm score, Tegner activity score and the SF36 score. In each patient, an ipsilateral four-strand semi-tendinosus/gracilis tendon graft was used. The femoral tunnel was drilled through the anteromedial portal independent of the tibial tunnel as per the technique described by Leo Pinczewski, Sydney, Australia. This technique was used to place the femoral end of the graft in a more lateral position than obtained by the traditional transtibial technique. The ACL graft was fixed using RCI interference screws. All patients underwent standard accelerated rehabilitation program. All patients were reviewed clinically and radiologically at a mean follow-up 9 months. A significant improvement was noted in all the scores at the time of follow-up. Radiologically all femoral and tibial tunnels were satisfactorily placed with the femoral tunnels being in the 10 o’clock or 2 o’clock position with no evidence of tunnel widening. None of the grafts had failed. We feel that this technique may allow better rotational stability following ACL reconstruction.

Purpose: To determine whether the tendon harvester can influence harvested tendon characteristics and soft tissue disruption

Summary: We compared two harvesters with regards to the length of tendon obtained and soft tissue disruption during hamstring tendon harvesting. Thirty six semitendinosus and gracilis tendons were harvested using either a closed stripper or a blade harvester in 18 paired knees from 9 human fresh cadavers. Use of the blade harvester gave longer lengths of usable tendon (p=0.002), whilst minimising the stripping of muscle (p=0.013).

Conclusion: Our results suggest that the type of harvester per se can influence the length of tendon harvested as well as soft tissue disruption. Requesting such data from the industry prior to deciding which harvester to use seems desirable.

Statement of purpose: To evaluate survivorship and knee function in patients who have undergone Kinematic Condylar Total Knee Replacement at a minimum of 15 years.

Methods: We evaluated all patients undergoing primary cemented TKR with the Kinematic Condylar implant (Howmedica), between January 1981 and December 1988. All operations were performed by a single surgeon through a medial parapatellar approach, with sparing of the PCL, all cemented and no patellae resurfaced.

Operation notes were analysed to confirm the type of procedure, underlying diagnosis, and thickness of tibial insert. Information was derived from patient records and postal questionnaire to all surviving patients, which included: WOMAC, SF-36, satisfaction scale and history of revision surgery.

Results: We have identified a total of 804 consecutive cases, 185 of these were bilateral giving a total of 619 patients. Mean age at implantation was 66 (range 17 to 83), with female:male ratio of 3:1. The underlying diagnosis was Osteoarthritis in 49%, and Rheumatoid Arthritis in 51% of patients.

As at September 2003 there were 153 patients (25%) still alive, using revision as an endpoint survivorship was 59.3% at a mean time since implantation of 17 years 8 months. Pain and function portions of the WOMAC questionnaire revealed mean scores of 37 and 47 out of 100.

Conclusion: This cohort has been shown to have 92% implant survivorship at ten years. We have shown that the survivorship deteriorates significantly between 10 and 17 years. Functional and pain scores after 17 years for patients with surviving implants were poor.

Survival was significantly better in females, no effect from pre-operative diagnosis was seen. 73% of these patients had 6mm tibial inserts, we postulate that the deterioration in survival is related to accelerated poly-ethylene wear beyond 10 years.
