Table 2

Tang et al. classification of peritendinous adhesion formation.

Stage	Characteristic features
1	No apparent adhesions, preserved peritendinous space
2	Minimal adhesions, peritendinous space preserved in most areas
3	Moderate adhesions, peritendinous space preserved in more than 50% of the tendon circumference
4	Severe adhesions, peritendinous space obliterated in more than 50% of the tendon circumference
5	Completely tethered tendon, no preserved peritendinous space
