Background: There is limited evidence on long-term outcome following ACL reconstruction. Concern has been raised that degenerative joint disease is common in the long-term and this may be associated with use of patellar tendon autograft.

Methods: 162 patients underwent single-surgeon arthroscopic ACL reconstruction (1991–1993) were identified from our prospective database. Patient-centred outcome was by Lysholm and Subjective IKDC score, objective outcome measures were clinical examination, arthrometry and X-rays.

Results: 13 year outcome (10–15 years) is known in 115/161 patients (71%). The median subjective scores were 94% (Lysholm) and 90% (IKDC). Ipsilateral graft rupture rate was 4%, with contralateral ACL injury in 8%. Mean manual maximum KT 1000 was 9mm in the grafted knee and 8mm in the contralateral knee. Clinical laxity scores of grade 0 or 1 were found in over 93% patients. Radiographically 66% were normal or near normal (Grade A or B). When compared to the contra-lateral uninjured knee we found no significant difference in the proportion of normal/near normal x-rays (grade A/B) versus abnormal/severe (grade C/D) for the medial, lateral nor patellofemoral compartments. There was no significant difference in the radiological IKDC grades in the medial compartment when compared to the contra-lateral uninjured knee, but there was a difference in the lateral and patellofemoral joints.

Conclusions: At 13 years patellar tendon ACLR provides excellent patient satisfaction, with clinically objective knee stability and low risk of re-rupture. Radiographically degenerative change was seen in 34%. There was no significant side to side difference to the uninjured contralateral medial knee joint, but there was a small but significant difference in the lateral and patellofemoral joints. The lateral joint differences may reflect underlying bone bruising at the time of injury. We do not believe that the patellar tendon autograft is the cause of arthrosis after BTB ACLR.

The purpose of study was to investigate kneeling ability after total knee replacement.

100 patients who were at least one year following routine uncemented primary total knee replacement were identified.

32% of patients stated they were able to kneel without significant discomfort. 64 (64%) of patients were actually able to demonstrate kneeling ability without pain or discomfort or with mild discomfort only. 24 (24%) of patients were therefore unable to demonstrate the ability to kneel because of discomfort in the knee.

There was no difference in the “kneelers” and “non-kneelers” with regard to overall knee score, range of motion and the presence of patella resurfacing.

To document the incidence of intra-articular pathology resulting from delayed Anterior Cruciate Ligament (ACL) reconstruction

A prospective assessment of meniscal and chondral damage found at the time of primary ACL reconstruction, and the relationship of incidence of intra-articular pathology to time since original ACL injury.

We reviewed 1960 patients who had undergone a primary ACL reconstruction. There were 1443 Males and 517 females, with an average age of 28.3 years. The average age at injury was 25.4 years.

1136 patients (58%) had secondary intra-articular pathology, 621 (54.7%) had a medial meniscal tear, 594 (52.4%) had a lateral meniscal tear and 381 (33.5%) had chondral damage. The average time from injury to reconstruction was 2.9 years (34.8 months) Those with secondary intraarticular pathology presented for reconstruction later, average 3.9 years (46.8 months), compared to those without secondary pathology, average 1.5 years (18 months).

The incidence of secondary intra-articular pathology increased with delay between original ACL injury and reconstruction. 41% of those waiting 12 months; 60% of those waiting 3 years; 79% of those waiting 5 years and 88% of those waiting 10 years had secondary intra-articular pathology.

This study confirms the relationship between an unstable ACL deficient knee and the incidence of secondary intra-articular pathology. Furthermore, our study reveals the increasing incidence of meniscal and chondral pathology the greater the delay from injury to ACL reconstruction. To prevent unnecessary secondary intra-articular pathology we recommend ACL reconstruction is performed with minimal delay.
