Surgically treated acute knee dislocations with knee stiffness perform equally as well as non-stiff knees when treated with arthroscopic arthrolysis.

Patients, whether undergoing LOA or not, performed equally well in terms of ROM and clinical scores at final follow up, while timing of LOA appears less critical. LOA is a simple, durable and safe method of treating ROM deficits in patients treated for acute knee dislocation, with very good results.
