Editorial Commentary: To Pump or Not to Pump? Gravity Versus Fluid Pumps for Shoulder and Knee Arthroscopy
1Murray, Utah.
Abstract:
Recent studies and our clinical experience have supported the safety and efficacy of various arthroscopic pumps for use in practice. Different pump designs are to be used in different ways. Although gravity flow can lead to constant low pressure in a cadaveric knee or shoulder, it may not provide optimal visualization or performance to best complete your surgical procedure. To take the best care of our patients, understanding basic fluid pump design and understanding what pump design resides in your operating room is important for all practicing arthroscopists.

ATP Driven Pumps II: P-type Pumps
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...
Pumped Concrete
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...
