The aim of this study was to establish consensus statements on the diagnosis, nonoperative management, and indications, if any, for medial patellofemoral complex (MPFC) repair in patients with patellar instability, using the modified Delphi approach. A total of 60 surgeons from 11 countries were invited to develop consensus statements based on their expertise in this area. They were assigned to one of seven working groups defined by subtopics of interest within patellar instability. Consensus was defined as achieving between 80% and 89% agreement, strong consensus was defined as between 90% and 99% agreement, and 100% agreement was considered to be unanimous.Aims
Methods
The aim of this study was to establish consensus statements on medial patellofemoral ligament (MPFL) reconstruction, anteromedialization tibial tubercle osteotomy, trochleoplasty, and rehabilitation and return to sporting activity in patients with patellar instability, using the modified Delphi process. This was the second part of a study dealing with these aspects of management in these patients. As in part I, a total of 60 surgeons from 11 countries contributed to the development of consensus statements based on their expertise in this area. They were assigned to one of seven working groups defined by subtopics of interest. Consensus was defined as achieving between 80% and 89% agreement, strong consensus was defined as between 90% and 99% agreement, and 100% agreement was considered unanimous.Aims
Methods
The purpose of this study was to report the outcome
of ‘isolated’ anterior cruciate ligament (ACL) ruptures treated with
anatomical endoscopic reconstruction using hamstring tendon autograft
at a mean of 15 years (14.25 to 16.9). A total of 100 consecutive
men and 100 consecutive women with ‘isolated’ ACL rupture underwent
four-strand hamstring tendon reconstruction with anteromedial portal
femoral tunnel drilling and interference screw fixation by a single
surgeon. Details were recorded pre-operatively and at one, two,
seven and 15 years post-operatively. Outcomes included clinical
examination, subjective and objective scoring systems, and radiological
assessment. At 15 years only eight of 118 patients (7%) had moderate
or severe osteo-arthritic changes (International Knee Documentation
Committee Grades C and D), and 79 of 152 patients (52%) still performed
very strenuous activities. Overall graft survival at 15 years was
83% (1.1% failure per year). Patients aged <
18 years at the
time of surgery and patients with >
2 mm of laxity at one year had
a threefold increase in the risk of suffering a rupture of the graft
(p = 0.002 and p = 0.001, respectively). There was no increase in
laxity of the graft over time. ACL reconstructive surgery in patients with an ‘isolated’ rupture
using this technique shows good results 15 years post-operatively
with respect to ligamentous stability, objective and subjective
outcomes, and does not appear to cause osteoarthritis.
Injury to the anterior cruciate ligament (ACL)
is one of the most devastating and frequent injuries of the knee. Surgical
reconstruction is the current standard of care for treatment of
ACL injuries in active patients. The widespread adoption of ACL
reconstruction over primary repair was based on early perception
of the limited healing capacity of the ACL. Although the majority
of ACL reconstruction surgeries successfully restore gross joint stability,
post-traumatic osteoarthritis is commonplace following these injuries,
even with ACL reconstruction. The development of new techniques
to limit the long-term clinical sequelae associated with ACL reconstruction
has been the main focus of research over the past decades. The improved
knowledge of healing, along with recent advances in tissue engineering
and regenerative medicine, has resulted in the discovery of novel
biologically augmented ACL-repair techniques that have satisfactory
outcomes in preclinical studies. This instructional review provides
a summary of the latest advances made in ACL repair. Cite this article:
