1. A patient lift apparatus comprising a supporting frame, a boom portion connected to the supporting frame via a pivot joint to allow the boom portion to pivot with respect to the supporting frame about a first pivot axis, a boom actuator to mechanically assist pivotal movement of the boom portion with respect to the supporting frame, and a leg/knee support connected to the supporting frame,
wherein the leg/knee support is configured to be selectively releasable from the supporting frame,
wherein the leg/knee support comprises a manually-operable release mechanism forming an integral part of the leg/knee support, which manually-operable release mechanism is configured to allow selective release of the leg/knee support from the supporting frame, said manually-operable release mechanism comprising:
a retaining device housed within an outer casing of the leg/knee support and configured to cooperate with a support mount provided on the supporting frame to secure the leg/knee support onto the supporting frame; and
a manually-operable handle cooperating with the retaining device to allow selective release of the retaining device from the support mount and thereby allow removal of the leg/knee support from the supporting frame.
