Will early reconstruction prevent abnormal kinematics after ACL injury? Two-year follow-up using dynamic radiostereometry in 14 patients operated with hamstring autografts.

Purpose: Previous studies have reported that Anterior Cruciate Ligament (ACL) reconstruction does not restore normal tibial rotation in patients with chronic instability and repeated episodes of giving way. We hypothesised that early ACL reconstruction, using quadruple hamstring autografts, before the pivoting episodes had occurred, would protect the knee joint from developing abnormal kinematics with increased external tibial rotation during flexion.

Methods: Fourteen consecutive patients (8 men, 6 women) with a median age of 24 years (18-43), with a complete, isolated unilateral ACL rupture and an intact contralateral knee, were studied.

A long-term, prospective, randomized study comparing biodegradable and metal interference screws in anterior cruciate ligament reconstruction surgery: radiographic results and clinical outcome.

Background: During the past decade, the use of biodegradable implants in anterior cruciate ligament surgery has increased.

Hypothesis: Poly-L-lactide acid (PLLA) interference screws would render the same clinical results but greater tunnel enlargement than metal screws 8 years after anterior cruciate ligament reconstruction using hamstring tendon (semitendinosus/gracilis) autografts.

Study Design: Randomized controlled trial; Level of evidence, 1.

Patellar tendon or semitendinosus tendon autografts for anterior cruciate ligament reconstruction: a prospective, randomized study with a 7-Year follow-up.

Background: The aim of the study was to compare the results after arthroscopic anterior cruciate ligament (ACL) reconstruction using central-third bone-patellar tendon-bone (BTB) autografts and triple/quadruple semitendinosus (ST) autografts.

Hypothesis: In the long-term, ACL reconstruction using BTB autografts will render more donor-site problems than ST autografts.

Study Design: Randomized controlled trial; Level of evidence, 1.

A prospective comparison of bone-patellar tendon-bone and hamstring tendon grafts for anterior cruciate ligament reconstruction in male patients.

The aim of the study was to compare the results after arthroscopic anterior cruciate ligament (ACL) reconstruction using central-third, bone-patellar tendon-bone (BPTB Group) (n = 45) and four-strand semitendinosus/gracilis (ST/G Group) (n = 78) autografts in male patients. The type of study is non-randomised, prospective consecutive series. A consecutive series of 126 male patients, all with unilateral ACL ruptures, was included in the study.

Biodegradable and metallic interference screws in anterior cruciate ligament reconstruction surgery using hamstring tendon grafts: prospective randomized study of radiographic results and clinical outcome.

Background: The use of biodegradable screws in anterior cruciate ligament reconstruction has grown in popularity.

Purpose: To compare the clinical and radiographic results in arthroscopically assisted anterior cruciate ligament reconstruction using 4-strand hamstring tendon grafts and either metallic (metal group) or biodegradable (PLLA group) interference screw fixation.

Study Design: Randomized controlled trial; Level of evidence, 1.

Outcome and risk factors after anterior cruciate ligament reconstruction: a follow-up study of 948 patients.

Purpose: The aim of the study was to assess the outcome and risk factors after anterior cruciate ligament (ACL) reconstruction in a large group of patients.

Type Of Study: Case series.

Methods: Included in this retrospective study were 948 patients (323 female, 625 male) with a symptomatic unilateral ACL rupture, who underwent arthroscopic reconstruction using patellar tendon autograft and interference screw fixation at 3 Swedish hospitals.

A prospective randomized comparison of bone-patellar tendon-bone and hamstring grafts for anterior cruciate ligament reconstruction.

Purpose: The aim of this study was to compare the results after arthroscopic anterior cruciate ligament (ACL) reconstruction using central-third, bone-patellar tendon-bone (BPTB group), 3-strand semitendinosus (ST group), or 4-strand semitendinosus/gracilis (ST/G group) autografts.

Type Of Study: Prospective randomized trial.

Methods: A randomized series of 134 patients, all with unilateral ACL rupture was included in the study.
