Second-look findings

Clinical outcomes compared with second-look findings

Comments

Defrere et al. [19] (CORR, 1994)

Invested or non-invested (based on synovial coverage and neovascularization)

Stability (Lachman test, PST), failure

Invested (25): perfect stability (21), slight instability (4)

Non-invested (22): perfect stability (13), slight instability (4), graft rupture in one half (1), Failure (4)

Toritsuka et al. [5] (AOTS, 2005)

Tension (probe test), integrity (tear)

KT-1000 (STSD)

1.1 mm (taut) v 2.3 mm (mildly lax/lax), p = 0.003

1.2 mm (minimal tear) v 1.2 mm (substantial tear), p = 0.670

Ahn et al. [6] (Arthroscopy, 2007)

Tension (probe test)

KT-2000

No statistical difference in KT-2000 measurements between “good tension” and “some laxity” group

Ahn et al. [22] (KSSTA, 2007)

Tension (probe test), tear, synovial coverage, notch reformation, cyclops lesion

KT-2000

Lysholm score

“Normal tension” group was significantly better than “slightly lax” group in KT-2000, but there was no significant difference in Lysholm score between groups

Graft tear, synovial coverage, notch reformation, and cyclops-like lesion showed no clinical correlation with KT-2000 and Lysholm score.

Kondo et al. [7] (Arthroscopy, 2007)

Three categories based on maturation score

Stability (KT-2000, PST) Clinical outcomes (ROM, Lysholm and IKDC score, mean isokinetic peak torque)

Category I showed significantly better results than categories II or III in KT-2000 and PST

No significant differences between the three categories in all clinical outcomes

Otsubo et al. [23] (KSSTA, 2007)

Three groups based on tension (probe test) and integrity

KT-1000, PST

No significant differences between the three groups in KT-1000 and PST

Lee et al. [24] (Arthroscopy, 2010)

Synovial coverage, integrity, tension (probe test), cyclops or impingement

IKDC grade

Normal synovial coverage group and normal tension group had significantly more cases with IKDC grade A/B than the abnormal groups

Integrity and impingement/cyclops made no difference in IKDC grade

Tanaka et al. [30] (KSSTA, 2012)

Graft damage and synovial coverage of PL

IKDC grade, Lachman test, PST, KT arthrometer

PL graft damage or synovial coverage showed no significant correlation with objective outcomes

Nakamae et al. [32] (BJJ, 2014)

Graft condition (integrity and tension), synovial coverage

KT-2000 and Lysholm score

Graft condition and extent of synovial coverage did not significantly affect the results of KT-2000 and Lysholm score
