Knee re­pla­ce­ment with sur­gi­cal ro­bot – Ori­gi­nal knee method

The CORI sys­tem is a state-of-the-art, ro­bot-as­sis­ted plat­form spe­ci­fi­cally de­ve­lo­ped for use in or­tho­pe­dic sur­gery. It is pri­ma­rily used for knee joint pro­sthe­sis im­plan­ta­tion and en­ables the sur­geon to plan and place the pro­sthe­sis with the hig­hest pre­cis­ion. The sys­tem uses a com­bi­na­tion of ad­van­ced ima­ging tech­ni­ques and real-time data pro­ces­sing to create a 3D view of the knee joint. This al­lows for in­di­vi­dual ad­apt­a­tion of the pro­sthe­sis to the pa­ti­en­t’s spe­ci­fic anatomy. 

Com­pared to other ro­bot-as­sis­ted sur­gi­cal sys­tems, the CORI sys­tem of­fers se­ve­ral ad­van­ta­ges. It is more com­pact and does not re­quire prior CT or MRI ima­ging, which ac­ce­le­ra­tes the plan­ning pro­cess and re­du­ces ra­dia­tion ex­po­sure for the pa­ti­ent. The sys­tem ope­ra­tes with a hand­held de­vice that pro­vi­des the sur­geon with pre­cise real-time in­s­truc­tions and sup­ports the sur­ge­on’s mo­ve­ments to op­ti­mally po­si­tion the pro­sthe­sis. This com­bi­na­tion of real-time feed­back and pre­cise con­trol makes the CORI sys­tem par­ti­cu­larly ef­fec­tive and safe. 

Ro­bot-as­sis­ted sur­gery with the CORI sys­tem of­fers num­e­rous be­ne­fits for pa­ti­ents. These in­clude hig­her pre­cis­ion in pro­sthe­sis pla­ce­ment, lea­ding to bet­ter func­tion and lon­ger du­ra­bi­lity of the pro­sthe­sis. Since the sys­tem sup­ports mi­ni­mally in­va­sive tech­ni­ques, there is less stress on the sur­roun­ding tis­sue, re­sul­ting in less post-ope­ra­tive pain and fas­ter re­co­very. Fur­ther­more, the risk of com­pli­ca­ti­ons such as pro­sthe­sis loo­sening or mal­po­si­tio­ning is re­du­ced, as the ro­bo­tic as­sistant sup­ports the sur­geon at every step. 

Ro­bot-as­sis­ted sur­gery with the CORI sys­tem is sui­ta­ble for a va­riety of pa­ti­ents who re­quire a knee joint pro­sthe­sis, espe­ci­ally in ca­ses of ad­van­ced os­teo­ar­thri­tis or other de­ge­ne­ra­tive joint di­se­a­ses. It is par­ti­cu­larly ad­van­ta­ge­ous for pa­ti­ents who need pre­cise ad­apt­a­tion of the pro­sthe­sis to their in­di­vi­dual ana­tomy to achieve the best pos­si­ble re­sults. A tho­rough ex­ami­na­tion and dia­gno­sis by the sur­geon are ne­ces­sary to de­ter­mine if this me­thod is the best choice. 

Pre­pa­ra­tion for sur­gery with the CORI sys­tem be­g­ins with a tho­rough ex­ami­na­tion and plan­ning by the sur­geon. Du­ring the ope­ra­tion, the CORI sys­tem is used to ana­lyze the pa­ti­en­t’s knee joint in real-time and create an exact 3D re­pre­sen­ta­tion. Ba­sed on this data, the sur­geon per­forms the pro­ce­dure with the help of the ro­bot-as­sis­ted hand­held de­vice, which en­ables pre­cise cuts and op­ti­mal pla­ce­ment of the pro­sthe­sis. Real-time mo­ni­to­ring en­su­res that the pro­sthe­sis fits per­fectly and the pro­ce­dure runs smoothly. 

As with any sur­gi­cal pro­ce­dure, ro­bot-as­sis­ted sur­gery with the CORI sys­tem also car­ries risks, in­clu­ding in­fec­tions, blood clots, or com­pli­ca­ti­ons re­la­ted to pro­sthe­sis im­plan­ta­tion. Ho­we­ver, the CORI sys­tem is de­si­gned to mi­ni­mize these risks by en­ab­ling ex­tre­mely pre­cise pla­ce­ment of the pro­sthe­sis and pro­vi­ding the sur­geon with real-time feed­back to avoid mal­po­si­tio­ning. Nevert­hel­ess, pa­ti­ents should be in­for­med about po­ten­tial risks be­fore sur­gery and dis­cuss with their sur­geon whe­ther this me­thod is sui­ta­ble for them. 

The re­co­very time af­ter sur­gery with the CORI sys­tem is ge­ne­rally shorter than with con­ven­tio­nal sur­gi­cal me­thods, as the mi­ni­mally in­va­sive tech­ni­que spa­res the sur­roun­ding tis­sue. Most pa­ti­ents can be­gin light mo­ve­ments wi­thin a few days and re­turn to their nor­mal ac­ti­vi­ties af­ter a few weeks. Full re­co­very, in­clu­ding a re­turn to sports ac­ti­vi­ties, can take se­ve­ral months. Tar­ge­ted phy­sio­the­rapy is cru­cial to res­tore mo­bi­lity and strength in the knee. 

The life­span of a knee joint pro­sthe­sis im­plan­ted with the CORI sys­tem can be ex­ten­ded by pre­cise pla­ce­ment and op­ti­mal ad­apt­a­tion to the pa­ti­en­t’s ana­tomy. Ge­ne­rally, mo­dern knee pro­s­the­ses last 15 to 20 ye­ars or lon­ger, de­pen­ding on the pa­ti­en­t’s phy­si­cal ac­ti­vity and the exact pla­ce­ment of the im­plant. Re­gu­lar fol­low-up ex­ami­na­ti­ons are im­portant to mo­ni­tor the con­di­tion of the pro­sthe­sis and ma­xi­mize its lifespan. 

The Na­tive Knee Tech­ni­que of­fers num­e­rous be­ne­fits for pa­ti­ents, in­clu­ding re­du­ced post­ope­ra­tive pain and fas­ter mo­bi­liza­tion. Thanks to the in­di­vi­dual re­con­s­truc­tion of the knee ana­tomy, this tech­ni­que al­lows for bet­ter mo­bi­lity and a more na­tu­ral fee­ling in the knee. Many pa­ti­ents re­port that af­ter sur­gery, they of­ten for­get they even have an ar­ti­fi­cial knee joint, as the func­tion­a­lity and sen­sa­tion are very si­mi­lar to those be­fore os­teo­ar­thri­tis. This si­gni­fi­cantly con­tri­bu­tes to an im­pro­ved qua­lity of life and pa­ti­ent satisfaction. 

The Na­tive Knee Tech­ni­que is par­ti­cu­larly sui­ta­ble for pa­ti­ents suf­fe­ring from knee os­teo­ar­thri­tis who wish to pre­serve their in­di­vi­dual mo­ve­ment pat­terns and knee ana­tomy as much as pos­si­ble. This tech­ni­que is ideal for pa­ti­ents see­king a knee re­pla­ce­ment that is not only pain-re­li­e­ving but also pre­ser­ves the na­tu­ral func­tion and feel of their ori­gi­nal knee. Th­rough pre­cise ad­apt­a­tion to in­di­vi­dual ana­tomy, the me­thod can also be ad­van­ta­ge­ous for pa­ti­ents who have achie­ved less sa­tis­fac­tory re­sults with con­ven­tio­nal knee prostheses.
